Embodiment Construction

[0014] Binaural hearing aids have two earphones, one for each ear. Some of these devices use binaural microphone algorithms, such as beamforming, to improve performance. Binaural microphone algorithms are discussed in US Patent Application 14 / 618,889, entitled "Conversation Assistance System," the disclosure of which is incorporated herein by reference. When only one earphone is in the ear, the input to the binaural microphone algorithm (e.g., beamforming for directional processing) changes because the microphone of the earphone not in the ear is no longer pointing in the same direction as the other microphones (e.g., the binaural viewing direction of the microphone array), and they are no longer in the same plane or position relative to the microphones of the headset in the ear. As a result, any processing using the microphones from both sides for the earphone in the ear is degraded.

Abstract

A method of operating a hearing aid system (10) comprising a binaural hearing device having first and second earphones (16, 18) each adapted to be worn on On, on or in one ear (17, 19). Each earphone (16, 18) has an electro-acoustic transducer that converts an input electrical audio signal intended for the ear into sound and at least one microphone that converts the sound into an electrical microphone output signal. A hearing aid system (10) is adapted to process microphone output signals from two earphones to generate electrical audio signals for driving transducers of the two earphones. In the event that one of the earphones (18) is detected not on, on or in the ear, and in response, processing of at least one of the microphone output signals producing an audio signal is modified.

Description

technical field [0001] The present disclosure relates to hearing aid systems. Background technique [0002] Some binaural hearing aid systems have two earbuds (or other types of headphones that deliver sound to the ears), one for each ear. Each headset has one or more microphones. The microphones on both ears can be used together to improve the performance of the system, for example through binaural beamforming. However, some users prefer single-ear devices due to reduced stigma, ease of communicating social availability, having only one-sided hearing loss, or other motivations. In a system where the two earphones are connected in some way (either physically with a wire or through wireless communication), a user who prefers to use only one earphone may leave the other earphone against the neck or shoulder, or conceal it under a shirt Either placed in a pocket, or placed in a storage case, or "parked" to the neck piece (which is part of the system) via a magnet, mechanical...
