A hearing device is physically adjusted to suit a hearing device wearer. A position sensor of the hearing device is used to ascertain a characteristic measure of a current actual wearing position of the hearing device. The characteristic measure of the actual wearing position is then taken as a basis for ascertaining a discrepancy between the actual wearing position and a prescribed desired wearing position. On the basis of this discrepancy, an instruction is output to the hearing device wearer to adjust the receiver connector based on the ascertained discrepancy.

Techniques used to selectively amplify audio signals are described herein in connection with audio amplification electronic devices, such as hearing aids, including over-the-ear hearing aids. A device and its operation are described to facilitate setting low and high tone/volume controls separately, using at least two selection mechanisms. In one aspect, a first selection mechanism includes a pitch frequency control rocker switch and the second selection mechanism includes a bass frequency control rocker switch disposed separately. In one aspect, the bass frequency control rocker switch causes a processor to bias the frequency response of the sound amplifier for frequencies below 1 kHz. In another aspect, the pitch frequency control rocker switch causes a processor to bias the frequency response of the hearing for frequencies above 1 kHz. In another aspect, the selection mechanism involves the separate attenuation of treble and bass adjustments in response to a user selection of a rocker switch setting for each adjustment.
