摘要

Hearing protection comprises a mass-produced otoplasty (1) comprising a channel (2) containing an acoustic filter (3) with noise level-dependent damping properties. An independent claim is also included for hearing protection comprising a standard ear plug having a channel containing an acoustic filter with noise level-dependent damping properties. Preferred Features: An additional filter (4) can be inserted in the channel for protection against constant noise.
