Abstract

A signal processing device according to an embodiment includes a measurement signal generation unit that generates a first measurement signal and outputs the signal to headphones, a sound pickup signal acquisition unit that acquires a first sound pickup signal obtained by picking up the first measurement signal by a microphone, a signal analysis unit that calculates a frequency response of the first sound pickup signal, a fit determination unit that determine a fit of the headphones by comparing a response value of the frequency response in a specified frequency band with a reference value, and a display unit that outputs gradual results of the determination in accordance with a percentage of the response value with respect to the reference value.
