There are many national level noise pollution rules that exist. And it provides the minimum basis for protecting the workers from harmful noise. However, those directives talk about the lower & upper action values as well as limit values. Besides, these are done based on daily or weekly personal noise exposure levels. And the continuous C-weighted peak sound level. However, there is a need for the risk assessment to identify the people prone to exposure to noises. So, whether the workers are exposed to noises above the lower or upper action values. And whether the work locations or tasks are prone to their exposure. Thus, that’s how the ear protector should be provided to the one who needs it.
