How it works

A noise barrier is a solid structure that intercepts and reduces sound. Certain materials like solid metal can reflect sound waves and enhance the sound. Noise absorbing walls, on the other hand, effectively reduce noise. Our standard 70mm panel wall can reduce up to 28 decibels, and our double panel wall will reduce up to 39 decibels of sound.

Human perception
of sound

With each ten decibels increase, the sound is doubled. For example, 60 decibels to 70 decibels sounds twice as loud to the human ear. Our acoustic wall system works effectively to reduce sound. Consult with a BelAire expert to create maximum sound reduction for your property.
