It allows for the release of overpressure in the event of an explosion while attenuating the noise generated.
Acoustic Explosion Vent: Safety and Sound Attenuation in Case of Decompression
Écib designs acoustic explosion vents to limit noise propagation during emergency decompressions while ensuring facility safety.

Why install an acoustic explosion vent on your sensitive equipment?
An acoustic explosion vent is a technical device designed to rapidly release internal overpressure (due to an explosion or degassing) while significantly reducing the acoustic impact of this decompression.
At Écib, we design and manufacture custom acoustic explosion vents, tailored to the safety and acoustic performance requirements of the chemical, pharmaceutical, petrochemical, food processing, and waste treatment industries.
These devices consist of:
-
decompression panels calibrated to yield at a defined pressure threshold,
-
one or more high-performance silencers to limit the noise emitted upon activation,
-
an integrated structure that may include sensors, hatches, or a resistant enclosure.
The objective is twofold: to protect installations from overpressure while limiting noise exposure for operators, nearby residents, or equipment. Écib vents can attenuate decompression noise by up to 40 dB, while complying with regulatory requirements (ATEX, ISO, CE, etc.).
Our teams support your projects from risk assessment through to on-site installation and acoustic validation.
Frequently asked questions about acoustic explosion vents
