摘要： The present application discloses methods, systems, and hearing prostheses for reducing wind noise and/or thermal noise in an audio signal transmitted to the user of a hearing prosthesis. A method in accordance with the present disclosure includes utilizing delay-sum beamforming to improve the signal-to-noise ratio in an audio signal that contains wind noise and/or thermal noise. In the presence of at least one of wind noise and thermal noise, amplitudes and phases of at least two input signals are matched. The two signals are then added together, resulting in an average improvement in the signal-to-noise ratio of the signal transmitted to the user of about 3 dB.

摘要： Methods and systems are disclosed for rate matching in a stimulating medical device, such as a cochlear implant or an auditory brain stimulator. In embodiments, the stimulating medical device applies a fast Fourier transform (FFT) at an analysis rate to the received signal to obtain a plurality frequency bin output signals. The stimulating medical device then applies a rate matching through interpolation function to the frequency bin output signals to match the stimulation rate for the stimulating medical device. This rate matching through interpolation function may apply a common interpolation filter to each frequency bin output to obtain a plurality of outputs distributed in time across the time period between executions of the FFT. The values of the frequency bin output signals at the time most closely matching the time for which stimulation is to be applied may then be selected and used in applying the stimulation.
