  • the selector is a potentiometer which controls the gain of an analog amplifier. In order to prevent penetration of moisture by the operating element, this is arranged liquid-tight on the outside of the housing part.
  • the axis of a potentiometer may be provided with an O-ring seal. Alternatively, slip ring seals or labyrinth seals are possible.
  • the selection device is a mechanical switch, its operating element can be sealed by means of a bellows. A pressure switch can be operated through an elastic housing part. Thus, the waterproofness of the hearing aid is not degraded by the external control. Nevertheless, the user gains in ease of use by being able to adapt his device to different operating conditions.
  • the hearing aid according to the invention has a third housing part which conducts an acoustic stimulus into the auditory canal of the user.
  • this may be a simple tube, which forwards the sound from a sound transducer integrated in the second housing part.
  • a sound transducer may be provided in the auditory canal of the user, which is electrically connected via the third housing part with the electronic component from the second housing part.
  • more electronic components are arranged in the third housing part.
  • a sound-permeable membrane at the top of the third housing part.
  • the tip is the one end of the housing part called, which is closest to the ear canal.
  • a membrane can be made, for example, from expanded polytetrafluoroethylene. This is permeable to sound waves, which are generated in the second or third housing part. Likewise, the membrane is permeable to gaseous water vapor. The penetration of liquid water, cerumen or sweat is reliably prevented. Thus, the third housing part remains clean and dry inside and the durability and reliability of the hearing aid is increased.
  • the hearing aid according to the invention can only generate noise as a tinnitus masker or, as an amplifier, record ambient noise through a microphone and release it back into the auditory canal of the user through a sound transducer.
  • a microphone opening is provided in one or more housing parts.
  • a microphone opening is provided in the second housing part.
  • the microphone opening is also sealed with a waterproof membrane.
  • these openings are also with a partially permeable membrane which allows air to penetrate and at the same time is impermeable to liquid water.
  • this membrane is preferably located substantially on the surface defined by the boundary line of the opening. As a result, the opening is closed with a taut membrane without bag-like protrusions of the membrane are present.
  • a further watertight membrane may be provided on the connecting surface between the first and the second housing part.
  • This may also consist of expanded polytetrafluoroethylene or, if the permeability to water vapor is secondary, of any other material.
