Do you hear that?
Metal shops in the film industry generally have average sound levels of 89 dBA; you should be wearing Class C hearing protection
Class C earplugs or earmuffs will provide enough protection for average sound levels in a metal shop. For louder work, such as cutting, welding, drilling, hammering etc, consider wearing Class A or B hearing protection. For noise above 110 dBA (roughly, the sound level of a power saw) consider wearing earmuffs (Class B) and earplugs (Class A) together.
