Problems solved by technology

However, the effect of feedback reduction is limited because the sound quality of a typical telephone is not optimal for hearing aid applications, and speech intelligibility is further reduced by small amplification or limited bandwidth

Embodiment Construction

[0022] The examples described in detail below represent preferred embodiments of the invention.

[0023] figure 2 The illustrated communication system according to the invention comprises a mobile radiotelephone 10 as a telephone device and a hearing aid 11 (here a behind-the-ear hearing aid) as a hearing device. Even if a mobile phone is selected as the telephone device in the example, a landline phone such as a wired or cordless phone may be used as the telephone device. Likewise, instead of a behind-the-ear hearing aid, an in-the-ear hearing aid or, if necessary, a headset or headphones can be used as the hearing device.

[0024] The hearing aid 11 basically possesses the same signal processing components as the hearing aid in FIG. 1 . See the description of FIG. 1 in this regard. but for clarity in figure 2 Only the microphone 12 and the signal processing device 13 are shown in . The microphone 12 receives ambient sound, converts it into a corresponding electrical sig...

Abstract

A communications system is configured to reduce the risk of feedback artifacts and contains a telephone device and a listening device. Accordingly, the communication system is thus provided, in which the signal processing in the telephone device is tuned to the listening device and the listening device is configured to process the voice and data signal inversely to the signal processing. Before the acoustic signal is transmitted from the telephone to the listening device, a frequency compression can thus be carried out, and in the listening device an inverse frequency compression can be carried out. This reduces feedback artifacts.

Description

technical field [0001] The invention relates to a communication system with a telephone device for carrying out telephone conversations and a hearing device for wearing in or on the ear and for outputting stimuli perceptible via the auditory organs, wherein useful signals are in the telephone device It undergoes signal processing and is transmitted on the acoustic path to the hearing device. Furthermore, the invention relates to a method for transmitting a useful signal over an acoustic path from a telephone device to a hearing device. Background technique [0002] Hearing device is understood here to be any sound output device or other device which outputs stimuli perceivable by the auditory organs which can be worn in or on the ear, in particular hearing aids, headsets, head-mounted Headphones, wait. Furthermore, a telephone device is here to be understood as any telephone device, in particular a mobile radiotelephone, a cordless telephone, a corded telephone, etc. [0...
