Exposure to high noise is a significant health hazard and as such there are regulatory requirements for control on noise or atleast workers' exposure to noise within the prescribed limits.
What I'm confused about is the exposure limit v/s noise level. Here's an example to clarify my question - if the noise level is 95 dBA, the maximum prescribed limit for human exposure is 4 Hrs. I'm not sure of the exact meaning of this requirement and thus have the following queries:
a) Is it permissible for a worker to work for 4 hours a day at 95 dBA without hearing protectors?
b) Is it permissible for a worker to work for 4 hours at 110 dBA with hearing protectors that provide 15 dBA noise attenuation?
c) or after using the above said hearing protectors, can a worker be made to work for 8 hours in a 95 dBA noise environment?
Before putting up here, I went through the noise rules, searched the internet and other resources but the confusion still prevails.
Request your opinions/comments on the interpretation of this regulatory requirement.
Thanks.
