AN INTERCHANGEABLE ACOUSTIC SYSTEM FOR A HEARING AID, AND A HEARING AID

摘要

An acoustic system ( 3 ) for a hearing aid is adapted for conducting sound from an output transducer in the hearing aid housing to an ear of a user. The acoustic system ( 3 ) comprises an encoding ( 8, 9 ) indicating acoustical properties of the acoustic system ( 3 ). Hereby the electronics of the hearing aid can identify the type of acoustic system attached to the hearing aid housing. The invention further provides a hearing aid with an acoustic system.
