What You Need To Know About Acoustic Silencers
Turbines, blowers, vacuum pumps, compressors and motors create a high volume of noise through their duct systems. And this can provide a serious issue to the health of both employees and personnel and nearby residents. Due to this, legal provisions are imposed in Australia regarding limitations on the production of industrial noise.
A manufacturer may face legal action if they fail to amend to what their local state requires in terms of industrial noise. This being the case, acoustic silencers should be deployed and constructed rightfully.
There is a wide range of acoustic silencers available to minimise the noise to acceptable levels. Let’s explore some of the options here: http://www.aletek.com.au/diesel-silencer-muffler
Industrial blower silencers
This type of acoustic silencer minimises the noise level from industrial blowers, vacuum pumps and compressors. They are intended for use as discharge or inlet and are utilised to give the optimal reduction of rotary or reciprocating positive displacement vacuum pumps or blowers and reciprocating compressors.
Industrial vent silencers
This can minimise the high volume of noise radiating from the vents, pressure vessel blow downs and steam outlets. It features a concentric absorptive section and a blast chamber to slow down the discharge.
This type of acoustic silencers uses resonance to attain high attenuation at frequencies between low to middle. They are regularly used on compressors, blowers and engine exhaust. Reactive mufflers are mainly suitable for applications like on food processes where permeable infill resources or materials are not allowed.
These offer a huge amount of sound reduction over a wide middle to high-frequency range. Absorptive mufflers feature a straight through design to lessen back pressure. The high-temperature option of this acoustic silencer made it a good option for engine exhaust.
Lined/Combination reactive mufflers
These acoustic silencers are a combination of an absorptive muffler and a reactive muffler set in one package. These provide a very high sound decrease on a broad frequency range and they are specially made for inlets and outlets of the blower.
There are many services around Australia that can deliver to different manufacturers’ requirements. When looking for one, it is highly recommended that you seek a free consultation with an acoustic engineer to ensure that you will get exactly what your company requires. Most of the time their service and assessment come free of charge. You need to ask though whether it is non-obligatory as some may require you to hire their complete service to claim free assessment.
You can consider the company’s experience in terms of providing acoustic silencer application. Those that have the most experience can understand effectively the specific requirement your company requires to comply with your state law provisions.
More than just the silencing, the design is also a critical consideration to take, as this takes into account the back pressure and air volume flow. It is also required that the acoustic silencer will not in any way affect your industrial process. Most of the time the company advise a custom-made option to ensure that they can construct exactly what is needed.
Before coming up with an agreement or a deal, it is necessary that you check on the noise control guarantee they can provide, as this guarantee can assure you that the acoustic silencers installed can meet your business specific requirements.
