PROBLEM TO BE SOLVED: To provide a method, a device and a program for removing impulse response noise capable of removing non-signal noise included in measured impulse responses.SOLUTION: The method for removing impulse response noise includes: a non-signal noise detection step of detecting non-signal noise from a non-signal response beforehand measured in measurement space for measuring impulse responses; a probability density function calculation step of calculating a probability density function of the non-signal noise on the basis of the average and the variance of the non-signal noise; a confidence interval calculation step of calculating the range of amplitude indicating a predetermined confidence interval, on the basis of the probability density function; an average calculation step of calculating the average of beforehand measured multiple impulse responses; a non-response interval detection step of detecting amplitude included in the range of the amplitude of the confidence interval, among the average amplitude of the impulse responses, and detecting an interval including the detected amplitude as a non-response interval; and a non-response interval removal step of removing the non-response interval from the beforehand measured impulse responses. |
