Abstract
In one aspect, the disclosure features systems for providing auditory signals to a subject. The systems include a sensor front-end circuit configured to be connected to an acoustic sensor and to convert analog signals received from the acoustic sensor to digital electric signals. The systems further include a sound processor circuit configured to be connected to the sensor front-end circuit and receive the electric signals provided by the sensor front end circuit. The sound processor includes multiple filters that spectrally decompose the received electrical signals into multiple spectral channels during operation of the system. The multiple spectral channels include at least a low frequency channel and a high frequency channel and the sound processor circuit is configured to operate the low frequency channel at a sample rate lower than a sample rate of the high frequency channel.
