Exposure to loud noise can cause permanent hearing damage.
Damage can involve loss of hearing ability and people may also suffer a permanent sensation of noises or ringing in the ears, known as ´tinnitus´.

Factors that contribute to hearing damage are:
Action levels are values of ´daily personal exposure to noise (LEP,d)´ which depend on working area noise levels and exposure times. The first action level is 85 dB(A),LEP,d and the second action level is 90 dB(A),LEP,d. Some common levels for concrete activities are given below.
