Hearing aid in which signal processing is controlled based on a correlation between multiple input signals
First Claim
1. A hearing aid to be worn by a user for auditory compensation, said hearing aid comprising:
- a first microphone which converts a sound transmitted through air to a first input signal;
a second microphone which converts a sound transmitted through a body of the user to a second input signal;
an intention identification unit configured to determine a threshold such that the threshold is greater when a loudness of a noise detected from the first input signal is greater;
a hearing-aid processing control unit configured to generate control information for controlling signal processing, based on the second input signal when a correlation value between the first input signal and the second input signal is smaller than the threshold;
a hearing-aid signal processing unit configured to generate an output signal from the first input signal according to the generated control information, when said hearing-aid processing control unit generates the control information; and
an output unit configured to output, as a sound, the output signal generated by said hearing-aid signal processing unit.

Abstract
The user'"'"'s personal intention is conveyed to a hearing aid using a method that does not place heavy physical and psychological loads. A hearing aid to be worn by a user for auditory compensation comprises: at least one microphone which converts a sound to an input signal; a hearing-aid signal processing unit configured to generate an output signal from the input signal; a receiver which outputs, as a sound, the output signal generated by the hearing-aid signal processing unit; and a hearing-aid processing control unit configured to generate control information for controlling signal processing, based on a non-audible sound which is made by the user and is hard to hear from outside, wherein, when the hearing-aid processing control unit generates the control information, the hearing-aid signal processing unit is configured to generate the output signal according to the generated control information.
