If you work in an environment where there are frequent loud noises then you should
strongly consider having ear plugs to prevent hearing loss and chronic ringing. Many musicians that play in band or manage bands have hearing loss or tinnitus due to the loud sounds coming out of the speakers within close proximity to their ear drums. You'll notice that people who work at airports are always equipped with ear muffs, primarily because of the loud noises from the planes taking off. Loud noises are the leading tinnitus causes because most people do not wear protective gear in their ears when they should be. Using an ounce of prevention will keep you from having to deal a chronis problem that could greatly disrupt your life.
