When measuring an impulse response, it is possible to reduce the effect of ambient noise by measuring at a high sound pressure. However, the nonlinear distortion of a loudspeaker occurs during measurement at a high sound pressure. In this study, we first measured the nonlinear distortion of an impulse response at a high sound pressure that exceeded the rating of the measuring equipment. Harmonic distortion and fundamental wave distortion were observed as nonlinear distortion. However, we showed that it is possible to calculate room acoustic characteristics while avoiding the effect of distortion by using a signal, such as Log-SS, that can separate harmonic distortion. We also examined the possible problems occurring in measurement at a high sound pressure. |
