The object is to ensure that device signals intended, for example, to inform hearing aid wearers about program changes or the end of a battery's life are perceived independently of ambient noise. Provision is therefore made, for instance, for reducing the level of the input signal with the aid of a gain adjuster ( 12 ) so that a device signal from a generator ( 4 ) driven via a control element ( 6 ) such as, for example, a program-changing switch, and via a control logic ( 5 ) can be perceived. Other possible solutions are to change the level of the device signal as a function of the level of the input signal or to mute the input signal while the device signal is fed out.
