The sound trap absorbs noise in the air ducts, while the silencer reduces noise emissions in the flow or exhaust.
Acoustic silencers / Sound traps: solutions for attenuating ventilation and process noise
At Écib, we offer acoustic silencers, also known as sound traps, designed to effectively reduce noise generated by air flows and industrial equipment. These devices are essential for improving acoustic comfort in a variety of environments, from industrial buildings to ventilation systems and specific processes.
Sound traps and acoustic silencers: what are the differences, what applications?
What is an acoustic silencer?
An acoustic silencer, or sound trap, is a device designed to attenuate noise by absorbing sound waves while allowing air or gases to circulate. It generally consists of a rigid casing containing absorbent materials, such as mineral wool, which dissipate acoustic energy in the form of heat as the airflow passes through.
Current applications
Our acoustic silencers are suitable for a variety of applications, including :
-
Ventilation, air conditioning and heating (HVAC) networks
-
Technical room air intakes and exhausts
-
Pressurized air ducts
-
Heat engine exhausts
-
Industrial equipment such as compressors, chillers, cooling towers, etc.
They are custom-designed to meet the specific requirements of each project, taking into account acoustic and aeraulic objectives.
Our solutions
We offer a complete range of acoustic silencers to suit different needs:
-
Parallel baffle silencers: ideal for rectangular cross-sections, they are composed of absorbing baffles arranged in parallel, providing effective noise attenuation while ensuring low pressure drop.
-
Circular silencers: suitable for circular-section ducts, they offer optimum sound absorption thanks to their special design, which sometimes includes a central sound-absorbing bulb.
-
Reactive silencers: using the principle of destructive interference, they are particularly effective at attenuating low frequencies, especially in internal combustion engine exhaust systems.
Each solution is designed to integrate perfectly with your installation, while respecting space, acoustic performance and airflow constraints.
Frequently asked questions about sound traps and acoustic silencers
What's the difference between a sound trap and an acoustic silencer?
When should a sound trap be used?
When an air flow must pass through a wall, a roof or a casing while remaining silent.
Are acoustic silencers standardized?
Yes, they meet criteria for pressure drop, attenuation and compatibility with HVAC networks.
Can the two be combined in the same installation?
Yes, they are often used together in complex or acoustically demanding systems.
