A hearing prosthesis, the hearing prosthesis including a plurality of sound capture devices and a determinator configured to generate a parameter indicative of an orientation of the plurality of sound capture devices relative to a reference, wherein the hearing prosthesis is configured to adjust a direction of focus of the hearing prosthesis based on at least the parameter.
Methods and systems for assessing insertion position of hearing instrument
A speaker of a hearing instrument generates a sound that includes a range of frequencies. Furthermore, a microphone of the hearing instrument measures an acoustic response to the sound. A processing system classifies, based on the acoustic response to the sound, a depth of insertion of an in-ear assembly of the hearing instrument into an ear canal of a user. Additionally, the processing system generates an indication based on the depth of insertion of the in-ear assembly of the hearing instrument into the ear canal of the user.
Hearing assistance device with an accelerometer
A hearing assistance device is discussed that has one or more accelerometers, a user interface, and optionally a left/right determination module is configured to receive input data from the one or more accelerometers from user actions causing control signals as sensed by the accelerometers to trigger a program change for an audio configuration for the device selected from a group consisting of a change in amplification/volume control, a change in a mute mode, a change of a hear loss profile loaded into that hearing assistance device, and a change in a play-pause mode.
SYSTEMS AND METHODS FOR HEARING ASSISTANCE
Audio content captured by a plurality of microphones associated with a device, such as a hearing device, may be received. It may be determined that a first portion of the audio content is associated with a first microphone of the plurality of microphones. The first microphone may be a unidirectional microphone. Audio indicative of the first portion may be generated and sent to the device for output. It may be determined that a second portion of the audio content is associated with a second, different microphone of the plurality of microphones. The second microphone may be an omnidirectional microphone. Audio indicative of the second portion may be generated and sent to the device for output.
Hearing device comprising a microphone adapted to be located at or in the ear canal of a user
