Sep 01, 2010Noise with only a few exceptions, noise levels (dosimetry) are usually well above the MSHA Action limit of 85 dBA. Therefore most rock crushing operations need to have a hearing conservation program. which for most companies is just measuring their employees hearing (audiogram) every year.
