| 发明名称 | Characteristic correcting device and characteristic correcting method | ||
| 摘要 | According to one embodiment, a characteristic correcting device includes: a correction filter configured to correct sound quality characteristics of a plurality of bands in a frequency range of an input signal based on a frequency characteristic which is set in advance to generate an output signal; an input module configured to input a surrounding sound signal of sound around an output device outputting the output signal; and an adjusting module configured to reduce the number of the bands of which the sound quality characteristics are to be corrected of the bands in the frequency range of the input signal in accordance with an increase in amplitude of the surrounding sound signal which is input. | ||

| 主权项 | 1. A characteristic correcting device comprising: a filter to correct sound quality characteristics of a plurality of bands in a frequency range of an input signal based on a frequency characteristic which is set in advance to generate an output signal; an input terminal to receive a surrounding sound signal of sound around an output device outputting the output signal; and a processing circuitry to reduce the number of the bands of which the sound quality characteristics are to be corrected of the bands in the frequency range of the input signal in accordance with an increase in amplitude of the surrounding sound signal which is input, and to reduce the number of the bands of which the sound quality characteristics are to be corrected of the bands in the frequency range of the input signal except a neighborhood of a resonance frequency of the output device. | ||
