It is an unwanted or disturbing sound, but noise is an often overlooked source of environmental stress that can disrupt our everyday life and lead to serious health conditions.

In the built environment, specifers considering acoustic materials are looking to solve a noise problem. In the final part of a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, provides some guidance on material selection and suitability, and armed with all the relevant information, the specification of the right acoustic product.

 

Step 9 - Investigate material performances and suitability

Once Steps 1-8 have been explored, identified and understood, it would then require the selection of a material or combination of materials to use, with relevant criteria. This will involve research – most likely online – with manufacturer’s product literature being a good starting point. This information should not always be taken at face value. Differing methods of testing, which can produce variations in declared performance as well as clever wording like ‘up to x dB’ or ‘x dB at 4000Hz’, may be potentially confusing or misleading.  In addition to manufacturer’s product literature, look for test reports and investigate the material’s properties. Is it open cell? Does it contain high mass? How does it compare with the performance of similar products from other manufacturers?

An important consideration when investigating a potential material: is it practical to use in the application intended? Is there any evidence of its previous use and results in this application? What about customer feedback? Will it help in all points concluded in Steps 1-8 or will you require additional complimentary products? How does it perform in other disciplines, such as fire, movement or airtightness etc?  If in doubt, speak with a competent technical engineer, either independent or from the manufacturer. Include sketches, performance criteria etc, as the more information you provide, the better the guidance received back.

Step 10 - Specify the product

You now understand the source, the requirement from the receiver, how the sound travels between the two, what the design requirements are and their restraints. You have identified the areas to be enhanced acoustically and what is required from the detail to be compliant. You have understood the implications of placing materials, what the properties are required from them, and have investigated suitable materials and researched their suitability in the application. You have possibly sought additional confirmation from a technical source and been provided with guidance on materials to use and the method of installation to comply with the acoustic criteria and any other factors required.  So now you can specify, add to drawings, and define the installation.

Many people consider acoustics to be a ‘black art’, but by taking on board these 10 steps to acoustic specification, it’s possible to find the most compatible acoustic solution and one that will ensure a building’s interior sound environment is at an acceptable level.

It’s a given we live in a relatively noisy world and many of us like to sound-off about problems with noise pollution in our day-to-day life.

When it comes to buildings and the specification of an acoustic material, then chances are you are looking to solve a noise problem. In the fourth in a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, provides some insight into the effects of material placement and how acoustic materials fall into one of three camps - isolation, absorption and sound barrier.

Step 7 - Understand the effects of material placement

The placing of an acoustic material in a particular area may have differing effects. For example, the placement of a high-mass board around a noise source (acoustic enclosure) will increase the sound levels of the noise source while the mass board will reduce this increased level.  In other words, if a machine had measured levels at 500mm away of 60dB(A) and at 2000mm away of 54dB(A), the installation of a high- mass enclosure spaced on all sides and top at 1m away, would likely increase the level at 500mm away to 63dB(A) or higher due to sound reverberation inside the enclosure. Therefore, a material with a performance of say 20dB Rw would not reduce the level at 2000mm away from 54dB(A) to 34dB(A). It would instead be likely to be closer to 39dB(A) and only a 15dB drop, called an ‘Insertion Loss’. The use of a sound absorbing layer inside the enclosure would reduce the reverberant sound energy and therefore improve the performance of the enclosure.

If a material has an acoustic performance of 20dB Rw, the addition of a second layer directly to the first would not increase the performance to 40dB Rw. It would, based on the ‘Mass Law’, be only 26dB Rw. However, if the two layers were spaced apart, the improvement would be greater than the 6dB for doubling of the mass. The larger the gap, the better the improvement, but as with the enclosure above, the void between the layers is susceptible to sound energy build up due to the reverberations, so again, the use of a sound absorbing layer in-between would help. A good example of this is a plasterboard partition where more layers of board, thicker studs and the use of a mineral wool in the middle all effect the performance of the partition.

Step 8 - Material types, isolation, absorption, sound barrier

Acoustic materials generally fall into three types or categories, a) Isolation b) Absorption c) Sound Barrier.

Isolation materials are generally soft and resilient, such as cork, rubber etc, and are effectively used to break the connectivity of two rigid elements, thus reducing the structural sound transmission via this path. An example would be a shower pump where rotational elements in the pump cause vibrations in the pump housing, which if mechanically fixed to a floor, will transmit these vibrations into the floor. These in turn will radiate noise into the air like a speaker. The use of flexible rubber isolation pads between the pump and floor will significantly reduce this effect.

Absorption products are generally open cell structure materials (for porous absorbers) and reduce the amount of sound energy that is reflected off the surface. Typical materials would include mineral wool and acoustic foams. The sound energy an object emits is a combination of its sound power with direct sound transmission and the reflected sound transmission. For instance, if a mobile phone is playing music from its speaker in open parkland, the noise level will be one level. If it’s moved into a reflective hard surface area, such as a bathroom, and placed on a hard surface at the same volume, the noise level would be significantly higher. Introduction of absorption products into the room would reduce the reverberated sound energy and thus reduce the noise level.

Sound barriers are used to reduce airborne sound energy passing directly through a material or construction and are largely controlled by the mass of the material. A sound barrier would typically have a high mass - solid without open cells - such as a steel plate, plasterboard, barrier mats etc. The use of sound barriers between the noise source and the receiver can typically be in the form of an enclosure, wall or barrier. A typical example would be a stud partition splitting a room in two where the thicker the partition and more layers of plasterboard either side would increase the overall acoustic performance. Single homogenous panels are typically controlled by the ‘Mass Law’ of acoustics, where every doubling of the mass increases the sound reduction index by 6dB. Twin layer systems, such as a partition, with two mass lines and a separating gap (the larger the better) will outperform a single layer material of the same mass. The void between mass layers should be filled with an absorption material to reduce sound pressure build up inside the cavity due to reverberations. 

In my next blog, I’ll look at how specifiers need to investigate material performances and suitability and when armed with all the relevant information will be able to specify the right acoustic product.

We all like a bit of peace and quiet, but sound is all around us every day of our lives, and when it’s unwanted we call it ‘noise’. This can have an impact on our well-being and our level of performance when we are working.

If you are considering the specification of an acoustic material, then chances are you looking to solve a ‘noise’ problem.  In the third in a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, stresses the importance of design restraints and raises the question of what areas to treat - steps 5 and 6 to acoustic specification to mitigate against noise.

Step 5 - Understand the design restraints

When considering the specification of any acoustic material, other factors will invariably need to be considered. A building, for example, would need to have a number of attributes; light, air movement, fire safety, access, aesthetics and functionality to name but a few. For example, adding four layers of plasterboard to a window would make an excellent choice from an acoustic perspective, but very bad from a functionality perspective as there would no longer be a window, we would have a loss of light and visibility.  Therefore, the choice of what to use and the limits of its effectiveness would need to be balanced with these and other design factors and  restraints.  This may seem obvious, but specification of a treatment or material that is not acceptable to the client or architect is a waste.

Step 6 - Identify the areas to treat

Identification of the source and receiver, all possible sound paths along with understanding the design restraints should enable you to identify the areas that need to be treated and how they can be treated whilst maintaining the original design intent.

The old saying ‘a chain is only as strong as its weakest link’ is very apt in acoustic specification. There is absolutely no point in treating one area if for any reason another area of weakness cannot be uprated.  For example, a wall may have a very high acoustic performance, but within the wall there could be a window and a door, both of which offer low acoustic performance. You would therefore need to acoustically enhance both the window and the door. If you only uprated the door, the window would be the ‘performance limiting factor’ and the overall difference would be negligible despite time and money being spent on the door. Ultimately, it’s always best practice to acoustically treat the lowest-performing element or area.

In my next blog, I’ll provide some insight into the effects of material placement and how acoustic materials fall into one of three camps - isolation, absorption and sound barrier.

In the second in a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, looks at sound paths and unravels the complexities of acoustic criteria - steps 3 and 4 to acoustic specification to mitigate against noise.

While it is difficult today to escape sound completely, we experience a wide range of sounds in our day-to-day life and when it is unwanted, we classify it as ‘noise’. If you are considering the specification of an acoustic material, then chances are you have a ‘noise’ problem. In the second in a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, looks at sound paths and unravels the complexities of acoustic criteria - steps 3 and 4 to acoustic specification to mitigate against noise.

Step 3 - Identify the sound path / paths

More often than not, it is not possible to reduce the noise at source or insulate the receiver. When this is the case, the only option is to consider how the sound energy travels from the source to the receiver and by what mechanisms. Is it airborne, impact, structure-born sound transmission, a direct sound path or a flanking sound path (indirect)?

Only once the source, the receiver and the possible sound paths are understood, can a possible solution be considered to mitigate against it and therefore reduce the noise levels transmitted. An example would be a building façade, where the source may be a busy road, airport or railway line. The receiver would be the rooms inside and the path elements would be the façade and its acoustic properties.

In very simple terms, if the receiver was an office, internal desired noise levels may be 45dB(A), but an apartment may be 35dB(A). If you then know what the noise level of the source is, say for example, a road with noise levels of 70dB(A), then you would need the façade to reduce the sound by 25dB for an office, or 35dB for an apartment. Based on an allowance of 5dB difference between laboratory versus site measured values, the façade performance would likely be 30dB Rw for an office, or 40dB Rw for an apartment.

Step 4 - Understand the acoustic criteria

There are many references to the dB, such as ‘Rw’, ‘Dnf,w’, ‘LnT,w’, ‘DnT,w’ ‘Dne,w’ ‘Leq’ ‘Lmax’, to name but a few. It is very important to understand the differences between these as they are not numerically comparable. Stating a dB requirement is not enough. This is like degrees in temperature with 0 degrees Celsius, 32 degrees Fahrenheit, 273 degrees Kelvin and 427.67 degrees Rankine all being the same temperature. So if you say 300 degrees or 45dB it is not enough information. 45dB what?

Commonly used in high rise façade buildings in reference to airborne sound insulation is ‘Rw’, ‘Dnf,w’ and ‘DnT,w’. An Rw value is a laboratory test value for the direct sound transmission of a building component or construction, such as a floor, wall, door, glass etc. A Dnf,w value is also a laboratory test value for the flanking sound transmission of a system, such as a Raised Access Floor, Suspended Ceiling System, Façade System etc. A DnT,w is a final site measured value for ‘room-to-room’ or ‘floor-to-floor’ sound transmission and includes both direct and flanking sound transmission, airborne and structure born.

In my next blog, I’ll look into the design restraints when it comes to acoustic material and how you should always look to treat the lowest performing element.

In the first in a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, examines the source and the receiver, the first two steps to acoustic specification to mitigate against noise.

What is the definition of ‘noise’? It is simply unwanted sound and more often than not it will not only be an irritation but also a health and safety issue. If you are considering the specification of an acoustic material, then chances are you have a ‘noise’ problem. In the first in a series of blogs, Mike Carrick AMIOA, Head of Acoustics at Siderise Group, examines the source and the receiver, the first two steps to acoustic specification to mitigate against noise.

Step 1 - Understand the source

Whatever the source is, it will have a noise level,so the first thing to do is to ascertain that level, either by field instruments using a sound level meter or by manufacturers’ data if the source is a machine or similar. Ideally the data should be presented in Octave Bands or 1/3rd Octave Bands. Otherwise a single numerical value in dB(A), which will refer to either Sound Power (LW) or Sound Pressure (LP).

How does the source emit the sound energy? Is it airborne sound, structure-borne sound or a combination of both? Voices are generally airborne while a hammer hitting an object is generally impact/structure borne. A pump or speaker will generally be both airborne and structure borne, caused by vibrations transmitting through a rigid material. Whatever the source, the percentage attributed to each method will vary.

Step 2 - Understand the receiver

The receiver is quite simply the person or persons who hears the noise and finds it unacceptable.

In some instances, the remedial action would be to reduce the noise at source either by turning the volume down on a radio, or enclose the source with sound insulating materials. For example a pump could be mounted on rubber anti-vibration mats and enclosed with a combination of high mass and sound absorbent linings. Sometimes this is not possible due to the size of source and the practicality, as well as the need to feed the source with air or material etc.

If reducing noise at source is not possible, then it may be possible to insulate the receiver. A good example of this would be an acoustic control room in a noisy factory. This is where the workers are in a relatively small insulated room, or noise haven, inside a larger factory, providing protection from the harsh noise of machinery.

In my next blog, I’ll look at identifying the sound path and consider how sound energy travels from the source to the receiver. I’ll also lift the lid on acoustic terminology and bring some light to this dark art.

Graham Laws, Business Development Officer - "Acoustics is widely recognised as a complex and demanding subject. For Motoryacht engine rooms in particular, understanding the relevant acoustic issues can be extremely challenging".

Acoustics is widely recognised as a complex and demanding subject. For Marine craft engine rooms in particular, understanding the relevant acoustic issues can be extremely challenging.

An important objective for the boat builder is to achieve a condition where engine noise is controlled to the point where it does not become obtrusive within the recreation or accommodation areas of the boat. The ideal target is inaudibility.

The problem is that, as engines become more powerful, the noise they create increases. This results in ever increasing levels of noise pollution for the occupants and for anyone else in the near vicinity.

The drive for increased speed and power means the boat designer is always looking to reduce weight in the boat. Unfortunately, losing weight from the shell and dividing structures reduces the ability of these elements to stop noise. The surface mass of these structures is of primary importance in containing noise within the engine room and away from sensitive areas.

It is a simple fact that a marine engine is always going to create a high level of noise. The boat builder can do little to about this. However, measures can be taken to significantly reduce the level of noise escaping from the engine room. Of course an important issue for the builder is - what level of cost is associated with these corrective actions? In order to answer this question a basic understanding of the important principles and acoustic treatments is necessary - then a value engineering exercise can be undertaken.

Vibration Isolation

Firstly ensure correctly specified anti-vibration mountings are employed for the engine, generator/s and other vibrating equipment. Where possible, flexible connectors and isolated drive couplings should be incorporated.

Sound Insulation

Ensure that the enclosing structures forming the engine room / housing are free of gaps or apertures. The importance of these potential 'leakage' paths cannot be over emphasised. A single small hole can dramatically reduce the acoustic effectiveness of a bulkhead. A large aperture can almost entirely eliminate its sound reducing capability. If through air movement is required, then employ the minimum number of apertures for the purpose and design them in such away as to allow an air passage whilst attenuating noise. The techniques for doing this include: forcing the air through 2 or more bends; passing the air down a long thin duct lined with sound absorbing foam (or better containing foam splitters); or the use of proprietary products such as silencers or acoustic louvres. 

Once sound leakage has been addressed, it follows that noise break-out from the engine room must now arise from sound transmission through the enclosing structures (bulkheads, decks, etc.). To obtain further improvements it is necessary to apply treatments to these elements to improve their Sound Reduction Index (ability to reduce sound transmission). For lightweight structures this would normally consist of adding further mass in the form of a flexible 'spaced layer barrier' material. The term 'spaced' means that the heavy layer component is held away from the original substrate by means of an integral resilient isolation layer. The resultant twin wall system gives an improved performance over direct application of the barrier to the background surface. The thickness of the isolation layer is important. The greater the thickness the more substantial is the improvement.

A further advantage of some flexible limp high-mass barriers is that they substantially lessen the effect of 'Coincidence Dip'. This is a phenomenon associated with rigid sheet materials whereby at a certain frequency range there is a pronounced dip in their Sound Reduction Index (sound can pass through more easily at these frequencies).

Sound Absorption

Significant improvements in sound break-out from an engine room can be obtained by lining the internal surfaces of the room with a sound absorbent material. This has the effect of reducing the Sound Pressure Level within the engine room. In consequence sound levels outside will drop by a corresponding degree. The reduction in the internal SPL arises as a result of suppressing the 'reflected sound field' (noise that has bounced off one or more internal surfaces of the room).

The level of improvement obtained by absorption treatments is dependent on two factors. Firstly, what proportion of the internal surface area of the room is to be treated (the greater the proportion the better the results). Secondly, the ability of the material to absorb sound, referred to as the material's 'Sound Absorption Coefficient'.

The Sound Absorption Coefficient is effected not only by the nature of the material but also by its thickness. Thicker absorbent materials generally have improved performance, particularly in the low-frequency range.

Significant care should be exercised in selecting the right sound absorption material.

Sound absorbent materials invariably have an open cellular structure. Consequently, they tend to be relatively susceptible to damage, cannot easily be cleaned and can absorb liquids such as fuel or oil. These shortcomings are normally overcome by using a material with an applied facing. Unfortunately, the wrong selection of facing can substantially reduce the materials Sound Absorption Coefficient in the frequency range of interest.

Additionally, there is an increasing requirement for the material to have a high level of fire resistance. Also, light reflection characteristics, aesthetic qualities and ease of installation should also be carefully evaluated.

Damping / anti-drumming

Structures formed from rigid materials can be excited by vibration or airborne sound into acting as sound radiating surfaces. The direct application of specially formulated thin anti-drumming materials can substantially reduce these additional noise sources. Also, many of the flexible acoustic barriers and composite materials offer useful dampening properties.

The Composite Solution

One extremely practical and cost effective solution to the applied treatments previously described is a multi-function composite material. These products are specially formulated to provide the three important acoustic characteristics, plus the necessary practical properties from a single lining material.

A typical composite specification would comprise: a fire resistant foam base isolation layer, a limp heavy layer barrier, a fire resistant foam sound absorption layer and a wipeable oil and fuel resistant facing.

There are a number of different protective/decorative facings now available. Most of these will to some extent impair the Sound Absorption Coefficient of the sound absorbent foam (particularly in the higher frequencies). However, some specially developed facings can actually enhance sound absorption (particularly in the more problematic low and mid-frequency ranges associated with marine engines).

With so many factors to consider it is hardly surprising that many boat builders fail to adhere to the following checklist for optimised noise control:

  1. Employ effective engine anti-vibration mountings & associated isolation measures.
  2. Fully enclose the engine room if possible. Seal all possible sound leakage points. Incorporate sound attenuated air movement apertures.
  3. Improve the sound reduction performance of lightweight engine room structures using flexible spaced barriers. Use the thickest practical isolation layer thickness.
  4. Apply sound absorption linings to as many of the engine room surfaces as possible. Select a material employing an applied facing enhancing sound absorption in the frequency range of the greatest interest.

A Systematic Approach

There are two key questions first to be asked:

  • How much of a noise problem do I have?
  • Do I need to meet a specified noise level or do I just want the boat to be as quiet as possible to improve its commercial appeal?

The answers to these questions whilst not substantially influencing the approach will obviously alter the level and cost of the acoustic treatment finally undertaken.

The normal step by step assessment process can be divided into two main areas:

Basic Design Concepts

All too often many acoustic problems arise simply through inadequacies at the initial design stage. A comprehensive list of all potential areas to assess is not practical here but the following specific tips may prove of assistance.

As previously highlighted specify adequate anti-vibration measures for the engine, generator, etc. Remember that any connecting rigid pipes should ideally incorporate flexible connectors as these also represent potential routes for vibration transfer.

Consider air movement points into the engine room at any early stage. Provide sufficient room to provide sound attenuating measures such as extended lined ducts or silencers.

Review carefully the design of the dividing structures forming the engine room. Frequently these comprise a single sheet material attached to stiffeners. Consider the possibility of converting these to partition type elements i.e. twin sheet materials with an intervening airspace. Use a sound absorbing infill material in the void (there are now some very low weight materials for this purpose). Remember a partition construction will always outperform a single sheet solution of the same total mass.

Consider door / hatch positioning, their construction and incorporate an effective gasket / sealing system.

Allow sufficient room to permit the application of sound absorbent or composite linings to the internal surfaces of the engine room.

Remedial / material solutions

Assuming that all possible enhancements associated with initial design have been investigated, further improvements would now arise from the use of specialist acoustic materials. This is equally the case for instances where changes to the basic design are not possible (such as a refurbishment project).

Engine rooms / housings can be broadly categorised into the following types. The material approach for each would generally be different.

1. Those having a high sound leakage potential i.e. the enclosing structure has open apertures that cannot practically be sealed or closed.

2. No leakage potential i.e. a fully sealed enclosure (would normally therefore include sound attenuated air vents). 

The above groups can be further sub-divided into 2 types:

  •  Those without a neighbouring 'sound sensitive area'.
  •  Those with a dividing structure immediately adjoining a 'sound sensitive area'. The typical material approach associated with the above 4 possibilities is as follows:

1/A. Generally, sound absorption treatments only are employed. This is because noise break-out is predominantly arising from 'leakage' from apertures. There is in consequence little to be gained from the use of barrier or barrier composite products. However, if there is any suspicion that any of the enclosing elements may be 'drumming or panting' (normally this would occur with lightweight rigid materials), then utilising materials with dampening properties would be prudent. These might be either a multi-function absorption / barrier composite or an absorption / dampening layer composite.

 1/B. As 1/A except that the particular enclosing element/s directly adjoining the sensitive area (bulkhead, deck, etc.) should be treated with a multi-function absorption / barrier composite.

2/A. The use of multi-function absorption / barrier composites will generally show significant improvements in this type of enclosure. Their use may be either general or cost restricted to enclosing elements of weaker acoustic performance (normally the lightest constructions).

2/B. As 2/A except that the particular dividing element directly adjoining the sensitive area should be treated with a multi-function absorption / barrier composite having a high SRI improvement potential.

Material Selection

The process of selecting the optimum material/s may be simplified by the use of material profile charts. These profiles provide a quick means of visually assessing and comparing materials with reference to a range of specific characteristics. We provide materials profile charts against the following set of performance variables:

Sound Absorption: At Low, mid and high frequencies

SRI improvement: Ability of the material to improve the SRI (Sound Reduction Index) of lightweight sheet substrates such as thin metal, plywood or GRP. The exact increase will change dependent on the particular substrate. The value is based on the average improvement for 0.7mm steel and 12mm plywood.

Dampening: As for SRI improvement, dampening performance is greatly effected by the substrate material. The result is consequently an assessed guide value for a typical range of common marine substrate materials.

Fire Resistance.

Ease of Installation: An assessed value based on the requirement to use a separate adhesive and / or mechanical fixings. Self-adhesive backed products will record a high value.
