Protecting your hearing with Noise Reducing barriers


An acoustic enclosure can range in size from:

a small box or cover, to confine and absorb noise; to,
to a tractor cab or large machine enclosure, which isolates the operator from the noise.

Important Points to Watch

The wall material needs to be heavy enough to isolate the required amount of sound.
Use an absorbing layer on the inside to reduce sound build-up, (reverberation).
Seal off any gaps or openings by block off pieces (eg strips of rubber) and gunned sealant, or flexible flaps where openings are necessary.
Make sure any doors, hatches or removable panels have full seals on each contacting edge.
Make sure that the enclosure is not touching any vibrating part of the machine, or it may vibrate as well. Isolate any pipework which penetrates the enclosure by sealing the gap with a soft sealant.
Donít forget the machine (and you) will need ventilation. Provide silenced airflow ductwork.
