I've been required of late to work in an industrial environment.
It's loud. Extremely so. Despite supposedly having ear defenders supplied, I've so far had to supply my own. The only good ones I have are 3Ms with an integrated FM radio, which are forbidden, even with the radio off! My other ones just arent "quiet" enough to be able to hear speech.
Anybody had experience with any "active" noise supressing/cancelling type muffs that have a battery type circuit to reduce machinery noise. It's in a poultry slaughterhouse, which has multiple machines, motors, pumps, production lines and the like creating a constant noise.
From what little I've been able to glean from the interweb, most of these active defenders guard against loud intermittent noises such as gunshots. Does anybody know or have experience of the type that suppresses noise over a preset db. threshold, but allow lesser levels (i.e. speech) through?
Any personal experiences, or a guide to further reading or research sites would be greatly appreciated. I should also add that whatever is recommended should be sufficiently robust to withstand moderate levels of heat, humidity, water splash and freezing cold in operation.
