Hearing aid fitting procedure and processing based on subjective space representation

摘要

A system for hearing assistance devices to assist hearing aid fitting applied to individual differences in hearing impairment. The system is also usable for assisting fitting and use of hearing assistance devices for listeners of music. The method uses a subjective space approach to reduce the dimensionality of the fitting problem and a non-linear regression technology to interpolate among hearing aid parameter settings. This listener-driven method provides not only a technique for preferred aid fitting, but also information on individual differences and the effects of gain compensation on different musical styles.

1. A hearing assistance apparatus adapted to perform signal processing based on inputs from an input device, comprising:
a signal processor configured to execute a signal processing algorithm; and a controller configured to provide a plurality of parameters Z to the signal processing algorithm, the controller configured to receive N-dimensional coordinates from the input device and convert the N-dimensional coordinates into the plurality of parameters Z for the signal processing algorithm, wherein the N-dimensional coordinates represent organization of predetermined settings for the plurality of parameters Z in an N-dimensional space.
