Feature and transmission quality demonstration method for hearing aids

摘要

The method involves setting several hearing aids (2,2',2") in operation together at the same time in a region with equal operating conditions. A monitoring member is set on at least one ear of a hearing aid user. A given hearing aid is selected and monitored with the monitor member by the user. A suitable hearing aid has several hearing aid holders each having an adaptor member which can be coupled to a sound exit channel of the operable hearing aid. Each hearing aid may also have a sound pick up of an electroacoustic apparatus. The monitor member may be connected to the electroacoustic apparatus which may be activated by at least one operable switching element.
