Abstract
For testing a hearing device a hearing device set is proposed comprising at least one hearing device with at least one acoustical/electrical input converter, at least one electrical/acoustical output converter, at least one communication link tap at the outer surface of said device for wire-bound, optical, wireless or electromagnetic communication to the external, a packaging box for the device specifically conceived for holding the device therein, within said box an acoustical coupler with an acoustical input applicable to said acoustical output of said device and with an acoustical output applicable to the acoustical input of said device.
Claims23
A hearing device set comprising
- at least one hearing device with at least one acoustical/electrical input converter, at least one electrical/acoustical output converter, at least one communication link tap at an outer surface of said hearing device for wire-bound, optical, wireless or electromagnetic communication to an external of a computing unit,
- a packaging box for the hearing device adapted for holding the hearing device therein,
- within said box an acoustical coupler with an acoustical input applicable to an acoustical output of said hearing device and with an acoustical output applicable to an acoustical input of said hearing device.
Method for testing a hearing device with an input acoustical/electrical converter with an acoustical input, an output electrical/acoustical converter with an acoustical output, a computing unit with an input operationally connected to an output of said acoustical/electrical converter and with an output operationally connected to an input of said electrical/acoustical converter, comprising the steps of
- placing said hearing device in a packaging or storing box for the hearing device adapted for holding the hearing device therein, such that the acoustical output and the acoustical input of said hearing aid device being acoustically coupled;
- generating at least one initial electric drive signal representing an acoustical signal;
- driving said output converter for producing a corresponding acoustical signal being a function of said initial electric drive signal;
- tapping off a received electrical signal dependent from a signal at said output of said input converter, the input converter having received an acoustical input signal via the acoustical coupler from the acoustical output of said output converter;
- and
- determining from said received signal tapped off characteristic of signal transfer between said output converter and said input converter of said hearing aid device.
