Sound corrector, sound measurement device, sound reproducer, sound correction method, and sound measurement method

A sound measurement device comprising:

• a signal outputter configured to output a measurement signal to measure acoustical properties of an object to be measured;
• a response signal receiver configured to receive a response signal reflected from the object;
• a frequency specifier configured to specify a resonant frequency at a resonance peak from the response signal;
• a coefficient specifier configured to specify a correction coefficient of a correction filter for reducing the resonant frequency based on the resonant frequency;
• and
• a coefficient outputter configured to output the correction coefficient.

A sound correction method applied to a sound corrector, the sound correction method comprising:

• a signal outputter outputting a measurement signal to measure acoustical properties of an object to be measured;
• a response signal receiver receiving a response signal from the object in response to the measurement signal;
• a frequency specifier specifying a resonant frequency at a resonance peak from the response signal;
• a coefficient specifier specifying a correction coefficient of a correction filter for reducing the resonant frequency based on the resonant frequency;
• a filter performing filtering on an output signal to be output to the object using the correction filter with the correction coefficient;
• and
• an outputter outputting the output signal to the object.
