Abstract

In a hearing aid system having at least one hearing aid (1; 31), the incorrect matching between the signal processing unit (7; 37) of the hearing aid (1; 31) and the used receiver (10; 40). So, the hearing aid system automatically recognizing the model of the used receiver and automatic matching of the signal processing in the hearing aid (1; 31) are suggested. Therefore, the incorrect manual matching is avoided.

Description

technical field

[0001] The invention relates to a hearing aid system comprising at least one hearing aid having an input converter for receiving an input signal and converting it into an input electrical signal, a signal processing unit for processing and amplifying the input electrical signal and emitting an output electrical signal , and a receiver that converts the output electrical signal into an output acoustic signal. Background technique

[0002] Hearing aids are available in different power levels. These hearing aids are distinguished in particular by the type of receiver used in each case, on which the maximum output power and the maximum sound pressure level that can be generated depend. In a hearing aid that can be worn behind the ear, the so-called RIC-BTE (Receiver-in-Canal-behind-the-Ear) hearing aid, the receiver is located in the earplug in the ear canal when the hearing aid is worn. Hearing aids with different performances can be produced in the earplugs o...
