Definitions

  • the present invention relates to a hearing aid according to the Preamble of claim 1.
  • Hearing aids have a sound entry opening for recording of ambient sounds and a sound outlet for Delivery of the ambient sounds processed in the hearing aid. It is of the utmost importance that the Surrounding sounds in no way disturbing noises are superimposed, which subsequently like ambient sounds be treated. Annoying noises can The reason for this is that air currents on edges on or tear off near the hearing aid (demolition problem) or that air currents with different Speeds and / or directions in the area immediately in front of the microphone membrane cause this is moved (gradient problem). These two The causes mentioned can also occur in combination.
  • cover element which glued over the sound inlet opening of a hearing aid becomes.
  • the known cover element consists of several Layers that are glued together at the edges and that consist of porous materials, which are prevented is said to be on the edges of the inlet opening as a result of interfering noises occur when air currents break off.
  • EP-0 310 866 discloses that the Sound outlet opening to prevent the entry of Ear wax (cerumen) in the hearing aid with a Cover element, using a microporous material is proposed.
  • the Sound entry opening then covered with a cover element should be, provided it is an in-the-ear hearing aid (ITE hearing aid) acts, because obviously only exists then there is a risk of ear wax getting into the hearing aid arrives when it is placed in the ear. Measures for Reduction of annoying noises are from this Document cannot be removed. It is alone here to avoid pollution of hearing aids.
  • the present invention is therefore the object based on specifying a hearing aid in which the Noise is reduced.
  • the invention has the following advantages: Integration of at least one cover element in the hearing aid itself and the flush arrangement of the Cover element in the hearing aid housing edges are avoided, which are otherwise a source of noise, with which the Demolition problem is taken into account. At the same time but also the gradient problem is taken into account, by the cover element made of a porous, preferably made of is made of an open porous material and a certain Has thickness.
  • material for the Cover elements an open-pored polyethylene is particularly suitable.
