摘要： A system and method for generating a beamforming signal is disclosed. A beam forming signal is generated by disposing a first microphone and a second microphone in horizontal coplanar alignment. The first and second microphones are used to detect a known signal to generate a first response and a second response. The first response is processed along a first signal path communicatively linked to the first microphone, and the second response is processed along a second signal path communicatively linked to the second microphone. The first and second responses are matched, and the matched responses are combined to generate the beamforming signal on a combined signal path.

摘要： A method and system for implementing an acoustical front end customization are disclosed. The customization is implemented to optimize the sound level for each individual cochlear implant user. A known audio signal is generated using a sound source and captured by a microphone system. The captured sound signal is sampled at one or more locations along the signal processing pathway, and a spectrum is determined for the sampled signal and the known signal. A ratio of the two spectrums is related to the undesired transformation of the sampled signal, and a digital filter is designed based on the ratio to filter out the undesired transformation.

摘要： An exemplary system includes an electro-acoustic stimulation (EAS) subsystem and a volume control subsystem communicatively coupled to the EAS subsystem. The EAS subsystem is configured to direct a cochlear implant to apply electrical stimulation representative of audio content included in a first frequency band to a patient and to direct a receiver to apply acoustic stimulation representative of audio content included in a second frequency band to the patient. The volume control subsystem is configured to facilitate independent control of a volume associated with the electrical stimulation and a volume associated with the acoustic stimulation. Corresponding systems, devices, and methods are also disclosed.

摘要： Methods and systems for normalizing a spectral profile corresponding to an audio signal include detecting a spectral profile of an incoming audio signal and comparing the spectral profile of the incoming audio signal to a reference spectral profile. The methods further include using the comparison to determine an adjusted spectral profile that more closely matches the reference spectral profile than does the spectral profile of the incoming audio signal and applying electrical stimulation representative of the adjusted spectral profile to a cochlear implant patient.
