The maximum allowable sound from airflow

Ventx focuses on supplying first-rate industrial silencers for all of our clients. As the name implies, you use them to create quieter workplaces. We ensure we only use the finest materials for our products. This helps them to withstand the impact of thermal shock. They prove very useful whenever a gas vent is giving you grief.
Silencer installation is something that requires you to think of many things. One of the most important details is the maximum permitted airflow fabricated noise.
For most installations, a worry for silencer airflow noise isn’t necessary. This is because it doesn’t add to the universal system noises. This is especially true if it is near the noise’s source. In addition, there cannot be immoderate pressure drops.


It’s wise to assess the sound from airflow if the silencer’s static pressure dips pass 0.35″. You should also inspect it if the noise criterion is lower than RC-35(N). You may have put your silencer in or near the occupied space. If so, you’ll need to evaluate the airflow produced sounds here.
There’s one way of calculating the total acceptable silencer produced noise. You can use this method when the silencer is near or in the filled space. Deduct 5dB per octave from the room sound criterion spectrum.
Something we don’t recommend is picking silencers with pressure drops that top 0.35″. You need to be careful if your noise criterion is lower than RC-35(N) too. If it is, speak with a HVAC noise control specialist.
At Ventx, we provide multiple silencer designs, catering for any kind of gas vent or other noisy system. Our control valve silencers are some of the most popular. They ease the pressure of the gas flow. At the same time, they absorb a large amount of the noise that’s present.
