Abstract:
    A sound measuring apparatus includes an impulse response obtaining section obtaining an impulse response, a positive transform section performing a positive transform on the impulse response obtained by the impulse response obtaining section, a filter low-pass filtering the response waveform on which the positive transform was performed by the positive transform section, a frequency characteristic obtaining section obtaining a frequency characteristic of the impulse response obtained by the impulse response obtaining section, a filter characteristic setting section setting a filter characteristic of the low-pass filter so as to be variable depending upon the frequency characteristic obtained by the frequency characteristic obtaining section, and a measurement result obtaining section obtaining a measurement result about a predetermined measurement item based on the waveform obtained by the low-pass filter.
