How to measure green function experimentally in a room in the field of acoustics?
Give an impulse (like a clap or bomb) and measure the pressure. This will give the green function, is it correct?
Raja Kumar: The acoustic Green's function can be measured experimentally in a room using a device with two matched microphones mounted in a tube driven by a loudspeaker, combined with another microphone that represents the observation point. This method allows determining the complex ratio of the sound pressure at a given position to the volume acceleration of a monopole at another position.
What is matched microphones?
Do you mean characteristic impedance of microphones are same ?
Do another microphone for measuring also need to be of same type or class specification?
