AI Technical Summary

Technical Problem

Users face a burden when trying to listen to amplitude-modulated acoustic signals, as they can interfere with surrounding sounds, making it difficult to concentrate or be aware of environmental noises, and may not be appealing in certain situations.

Method used

A signal processing device integrated into an earphone with a microphone that acquires and modulates input acoustic signals to generate an output signal with a volume intensity corresponding to gamma wave frequencies, allowing users to listen to sounds for cognitive function improvement without playing back audio content, while reducing noise interference.

Benefits of technology

Enables users to promote listening to amplitude-modulated acoustic signals, reducing the burden and allowing improved cognitive function by inducing gamma waves in the brain, even in noisy environments, without the need to play back audio content.

Abstract

A signal processing device according to one embodiment of the present disclosure comprises: an acquisition means for acquiring an input acoustic signal based on a sound picked up by a microphone disposed in the vicinity of a user's ear; a generation means for generating an output acoustic signal having a variable volume corresponding to the frequency of a gamma wave by performing modulation processing, including amplitude modulation, on the input acoustic signal acquired by the acquisition means; and an output means for outputting the output acoustic signal generated by the generation means to a speaker from which a sound is emitted toward the user's ear.
