ABSTRACT:
A method for manufacturing an acoustical device, especially a hearing device. A device casing is provided with an acoustical/electrical input converter arrangement with an electric output. An audio signal processing unit establishes audio signal processing of the device according to individual needs and/or purpose of the device. At least one electrical/mechanical output converter is provided. A filter arrangement with adjustable high-pass characteristic has a control input for the characteristic. The following operational connections are established: between the output of the input converter arrangement and the input of the filter arrangement, between the output of the filter arrangement and the control input, between said output of the filter arrangement and the input of the processing unit, between the output of the processing unit and the input of the at least once output converter.
