Abstract
An ear-worn device includes: a microphone that obtains a sound and outputs a first sound signal of the sound obtained; a DSP that performs determination regarding an S/N ratio of the first sound signal, determination regarding a bandwidth with respect to a peak frequency in a power spectrum of the sound, and determination of whether the sound contains human voice, and outputs a second sound signal based on the first sound signal when the DSP determines that at least one of the S/N ratio or the bandwidth satisfies a predetermined requirement and the sound contains human voice; a loudspeaker that outputs a reproduced sound based on the second sound signal output; and a housing that contains the microphone, the DSP, and the loudspeaker.
