ABSTRACT OF THE DISCLOSURE The invention relates to a hearing aid with a housing insertable into the auditory canal, wherein the housing contains at least a microphone, an amplifier, an earpiece and a power source. In instruments of this kind it has turned out to be desirable to have, in addition to the usual volume control, an additional control by means of which the way the incoming sound signals are influenced by the amplifier (i.e. its characteristic) can be adapted to individual hearing impairments. For this purpose the invention provides in the space housing the battery a pitch control in such a manner that its actuating member can be operated at least when the power source is removed from the instrument. This makes it possible to reduce the space requirement for the pitch control so that even hearing aids insertable into the auditory canal can contain such an additional control.
