Abstract
In an exemplary embodiment, the signals to be transmitted are converted into electric signals and resolved into a multiplicity of frequency bands by means of filters. The signals coming from the filters are then employed for the modulation of tone signals. Finally, original tones are supplied to the person hard of hearing together with the modulated tones as the auditory signal. To this end, the disclosure provides that the resolution ensues into at least three frequency bands and that the frequencies of the modulated tones are adapted to the residual frequency band of the person hard of hearing and that all of the signals to be transmitted are transmitted together with the modulated tones and that the ratio of the loudness of the original tones and that of the modulated tones is set at a ratio which is useful for the person hard of hearing. For transmission to the person hard of hearing, standard earpieces can be employed or implanted devices with direct electric transmission of the signals to the auditory nerves. Disclosed methods and devices are particularly employable as a hearing aid device for persons who are very hard of hearing or who have total hearing impairment.
