Abstract
The present disclosure relates to a hearable device, an integrated circuit, and a biological signal measurement system that enable realization of acquisition of a cleaner biological signal. A noise reduction unit executes noise reduction of a biological signal of a user measured by a biological sensor using an output signal from at least one of a microphone or an inertial sensor as a reference signal. The present disclosure can be applied to a hearable device such as a TWS earphone.
Claims20
A hearable device comprising:
- a microphone;
- an inertial sensor;
- a biological sensor that measures a biological signal of a user;
- and
- a noise reduction unit that executes noise reduction of the biological signal using an output signal from at least one of the microphone or the inertial sensor as a reference signal.
An integrated circuit comprising
- a noise reduction unit that executes noise reduction of a biological signal of a user measured by a biological sensor using an output signal from at least one of a microphone or an inertial Sensor provided in a hearable device as a reference signal.
A biological signal measurement system comprising:
- a hearable device;
- a noise reduction unit that executes noise reduction of a biological signal of a user measured by a biological sensor using an output signal from at least one of a microphone or an inertial sensor provided in the hearable device as a reference signal;
- a feature amount extraction unit that extracts a feature amount from the biological signal subjected to the noise reduction;
- and
- a user state estimation unit that estimates a state of the user on a basis of the extracted feature amount.
