Embodiment Construction

[0054] As a conventional hearing aid, figure 1 The hearing aid 100 in includes a microphone 1 configured to receive an acoustic input signal 11 and convert the acoustic input signal 11 into an electrical input signal 12, an audiological signal connected to the microphone 1 and configured to process the electrical input signal 12 into a processed signal 18 A processing unit ("pre-processing") 8, an amplifier 9 connected to the audiological signal processing unit 8 and configured to amplify the processed signal 18 into an amplified signal 19, and connected to the amplifier 9 and configured to transform the amplified signal 19 A receiver (“speaker”) 10 for an acoustic output signal 20 .

[0055] Shown as a branch from the signal processing unit 8 is a howling detector 2 configured to detect the presence of feedback howling and to determine the frequency and amplitude (likely and duration) of the howling. Such as figure 1 As shown in , the processed signal 18 originating from ...

Abstract

The present application discloses a hearing aid comprising a feedback alarm. The hearing aid includes a microphone configured to receive a sound input signal and converting the sound input signal into an electric input signal; an audiological signal processing unit connected with the microphone and configured to process the the electric input signal into a processed signal; an amplifier connected with the audiological signal processing unit and configured to amplify the processed signal into an amplified signal; a receiver connected with the amplifier and configured to convert the amplified signal into a sound output signal; a howl detector connected with the signal processing unit and configured to detect the presence of a feedback howl originating from the hearing aid; an analyzer connected to the howl detector and configured to determine a first value indicative of whether or not the feedback howl detected is potentially audible to a person neighbouring the user of the hearing aid; and a trigger unit connected to the analyzer and configured to trigger a corrective action considering the first value.

Description

technical field [0001] The invention relates to hearing aids, in particular to a corresponding operating method of a hearing aid and to a corresponding computer program. Background technique [0002] It is often observed that a hearing aid user's hearing aid whistles for an extended period of time and is so loud that everyone around the user can hear it. Such howling or howling is caused by the insufficient feedback canceling capabilities of prior art hearing aids, and the situation can usually only be corrected by manual user action such as repositioning the hearing aid, or lowering the gain / volume. Since the user cannot hear the undesirable feedback, no action is taken until someone else brings the problem to the user's attention. This results in an annoying situation for friends, family, bystanders, and for the user himself. [0003] WO2011 / 026113A1 discloses a method and system for notifying a user of hearing aid feedback noise, including, for example, receiving an aco...
