Webment accurately. In this paper we consider the estimation of room geometry from room impulse responses as that facilitates a quick and practical measurement. The room impulse response, the transfer function between the sound source and the listener, characterises the acoustics environ-ment of a room. It is composed of direct-direction sound, early WebSound travels through time, and the way we perceive sound changes through time. Both of these factors need to be included in any evaluation of how a room sounds. Digging Deeper: ETC and the Impulse Window Sound never happens in an instant; by definition, sound is change over time.
