Abstract
A transfer function calculation unit is configured to calculate a transfer function from a sound source installed in a predetermined target direction to each microphone of a microphone array, and a determination unit is configured to determine whether or not the microphone array is normal on the basis of a difference amount between a transfer function to each microphone and a predetermined ideal transfer function to each microphone.
Claims7
A test device, comprising:
- a transfer function calculation unit configured to calculate a transfer function from a sound source installed in a predetermined target direction to each microphone of a microphone array;
