Problems solved by technology

Undesirable acoustic feedback results when the microphone of one of the prostheses picks up mechanical vibrations from either of the two prostheses, and then the corresponding prosthesis produces an output based on those vibrations

Embodiment Construction

[0024] For purposes of illustration, this disclosure generally refers to vibration-based hearing prostheses. However, the embodiments and examples disclosed herein are equally applicable to other types of hearing prostheses now known or later developed. Furthermore, some disclosed aspects can be applied to other acoustic devices or sound processors not necessarily associated with a hearing prosthesis.

[0025] figure 1 is a block diagram illustrating a hearing prosthesis 101 . Hearing prosthesis 101 may be a bone-anchored hearing prosthesis or other vibration-based hearing prosthesis, an acoustic hearing aid, a cochlear implant, a direct acoustic stimulation device, an auditory brainstem implant, or any other type configured to receive and a hearing prosthesis processing at least one signal from an audio transducer of the prosthesis. Much of the discussion herein concerns vibration-based hearing prosthesis systems, including bilateral hearing prosthesis systems with both c...

Abstract

A hearing prosthesis system includes a processor arranged to communicate a stimulation signal to a vibration stimulator of a first hearing prosthesis. The processor receives an indication of a measured input signal from a first transducer of a second hearing prosthesis. A processor calculates a feedback associated with the stimulation. The processor may also be further configured to adjust a gain table or an input to a feedback reduction algorithm in response to the calculated feedback. Additionally, the processor of the hearing prosthesis system may also be arranged to communicate a second stimulation signal to a vibration stimulator of the second hearing prosthesis. The processor receives an indication of a measured input signal from the first hearing prosthesis. Further, the processor calculates a second feedback associated with the second stimulation.

Description

[0001] Cross References to Related Applications [0002] Priority is claimed to US Provisional Patent Application No. 61 / 787991, filed March 15, 2013, the entire contents of which are hereby incorporated by reference. Priority is also claimed to US Patent Application Serial No. 13 / 915,424, filed July 11, 2013, the entire contents of which are hereby incorporated by reference. Background technique [0003] Various types of hearing prostheses provide the ability to perceive sound to people with different types of hearing loss. Hearing loss may be conductive, sensorineural, or some combination of both. Conductive hearing loss usually results from dysfunction of any of the mechanisms that normally transmit sound waves through the outer ear, tympanic membrane, or earbones of the middle ear. Sensorineural hearing loss typically results from a malfunction of the inner ear, including the cochlea, where sound vibrations are converted into nerve signals, or any other part of the ear,...
