Abstract
The invention relates to a hearing aid comprising an acoustic input aperture (SE) and an acoustic output aperture (SA), and a cover element (DE) covering the acoustic input aperture (SE). In the invention, the cover element (DE) is received in the hearing-aid housing and its surface is flush with that of said housing and said cover element is made of an open-pore material. The invention offers the advantage that on account of integrating the cover element (DE) into the hearing aid, spurious acoustic signals caused by air motion cannot arise at the hearing aid.
