1. A hearing aid device, comprising:
- at least one input transducer configured to acquire an input signal and transduce it into an electrical signal;
a detector for detecting a line signal that deflects an electron beam generated in an image tube output by a screen device that is devoid of any information encoded specifically for the hearing aid device;
a signal processing unit configured to process and amplify the electrical signal, the signal processing unit being adaptable to different auditory situations by at least one adjustable parameter that can be automatically adjusted dependent on the line signal, wherein one of the auditory situations is a display auditory situation and is selected whenever the hearing aid device is in the presence of a powered display and is deselected when the hearing aid device is not in the presence of a powered display; and
an output transducer to transduce the processed electrical signal into an acoustic or mechanical output signal.

Abstract
The correct recognition of the auditory situation “television” often poses a problem for hearing aid devices with automatic situation recognition, since a plurality of real situations are simulated by the television audio signal. To correctly recognize the situation “television”, the invention therefore provides to detect a line signal with a particular line signal frequency output by the television device, and given the existence of such a line signal to automatically implement the auditory situation “television”.
