The indoor impulse is used to estimate the indoor acoustic characteristic. The impulse response is the function that shows the acoustic propagation from the sound source to the microphone. And it contains important information of the indoor acoustic characteristic.The indoor impulse response is divided into the frame of the length of the fixed time. Attractor is composed by affine-transformation of each frame.
The frame which makes the Hausdorff distance becomes the shortest between the standard frame and attractor is decided. The above defined a self similarity structural analysis of the indoor impulse response.
Distribute of the frame which makes the Hausdorff distance becomes the shortest is concentrating at time zone.It is a characteristic of the impulse response analyzed by a self similarity structure.The relativity frequency distributed change is confirmed with the change of the indoor environment by using discriminant function. |
