Ventilation System Noise Control Silencer Types

There are several ways our acoustic specialists provide ventilation system noise control in your facility. Using silencers is a common solution that may help reduce noise in your facility from industrial fans and ventilation equipment. There are several different types of silencers our engineers may choose from to keep noise at bay. Our experts can help you select the right solutions based on your facility’s unique needs. However, it can be helpful to know some general information about common types of ventilation silencers.

Silencers for Ventilation System Noise Control

Acoustic silencers are products that help reduce noise. For example, they can help control noise from ventilation systems, machinery, and other equipment in your facility. Reducing noise is necessary for many industrial spaces, as loud noise poses many dangers to your workers and their productivity. Silencers can help keep noise levels at optimal levels.

Silencers help with ventilation system noise control for successful work environments.

There are two main types of silencers for ventilation noise control: absorptive and reactive. These products use different methods for decreasing noise levels. In many cases, one type may work better than the other for noise control. Therefore, it’s necessary to choose the right product for your noise control needs. Silencers can help control noise from various sources, including fans, exhaust systems, and ventilation ducting.

Absorptive Silencers for Noise Control

Absorptive silencers provide ventilation system noise control solutions by absorbing sound waves. These ventilation silencers use porous or fibrous materials that absorb sound waves and transfer sound energy into heat energy through friction. This weakens the sound waves to reduce noise in your facility.

Absorptive ventilation silencers are best for higher frequency noises. Of course, each silencer is a little different. However, absorptive options are typically effective for sounds between 500 and 8,000 Hz. When you’re experiencing high frequency noises from ventilation systems or other equipment in your facility, our acoustic specialists can help determine whether absorptive silencers will work best for your needs. In addition, our team can identify the thickness of the acoustic material needed for proper noise reduction.

Reactive Silencers for Ventilation System Noise Control

Reactive silencers are another sound attenuation solution for your ventilation systems. These types of ventilation silencers use sound reflection properties for ventilation system noise control. Reactive silencers are typically made of several chambers and perforated tubes to reflect sound and change direction of sound waves. This is similar to how a car muffler works to reduce engine noises. Reactive silencers may reflect sound back to the noise source or scatter it to weaken the sound waves.

Reactive silencers are typically easier to clean than absorptive silencers, as they are generally made of non-porous materials. Also, they are frequently smaller than absorptive silencers. These silencers are typically best for low to medium frequency sounds and are often used for machinery that produce pure tones. Our ventilation specialists can help you determine when reactive silencers are the best solution for your facility’s noise issues.
