Sound field measuring method and sound field measuring device |
摘要 |
A sound field measuring device according to the present invention uses a measurement signal which has at least one change point and whose frequency spectrum has a shape corresponding to a shape of a frequency spectrum of a background noise. This enables a sound field measurement, which is for measuring an impulse response or transfer function of a sound field space which is a linear time-invariant system to be measured, to be performed with a high S/N ratio over a wide frequency band.
