The information you need for an acoustic assessment

It’s our job to supply measures that lower the noise level in industrial settings. Said measures come in the form of our silencers. One other word we have for them is attenuator. Whatever it is you end up calling them, rest assured that they’ll serve your needs well.
When it comes to silencers, you must carry out an important procedure; an acoustic assessment of a ductwork run. This allows you to determine which silencer would be ideal for the situation. These tests have to be very accurate. As a result you must have the right information.


Firstly you must know what the reverberation time is. This is capable of altering the overall sound pressure. When the reverb time is low, so too will be the donation to the general sound level. It’s the opposite with high RTs.


While reverberation is crucial you also need to know the amount of absorption in a room. It can have a huge influence on the reverb and noise. It’s best to seek advice or consult a guide here so you get the rate right.

Distance to the listener

Another detail you need to be aware of is the distance to the listener. Measure from the source of the sound to the people who will be hearing the noise. Normally, with a ceiling mounted grille that has a 2.8m room height, you usually calculate this as 1.0m. Sometimes, this can change between sites because of the atmosphere. It shall also depend on the closeness of separate noise sensitive locales on site. This could include an office space.
At Ventx, we can offer our customers a host of interesting silencer and attenuator designs. This includes our direct in-line models. They create a minimum degree of pressure loss but achieve the necessary attenuation with an absorptive section.
If you want to know more about our solutions, please call us. We offer products for a wide array of different settings and always achieve the greatest results.
