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 one output converter.

The invention shall now be described in more details and referring to examples and with the help of figures.
The figures show by examples:
FIG. 1 wind spectra in dependency on wind direction;
In FIG. 1 there is shown wind noise spectral characteristic for a wind speed of 10 m/s at an individual head with no hair. Therefrom it might be seen that wind noise spectrum varies significantly as wind direction alters with respect to a device registering such noise. Nevertheless, wind noise spectrum is band-limited.
In FIG. 1 there is further schematically introduced the approximate frequency band for human speech fundamental pitch.
