The Sound Field Distribution Problem of Room Equalization

The success of room equalizing depends on the soiution at several dltierent problems.A central problem is the sensitivity of the system to changes In the position at the sound source as well as the receiver.The position at the sound source and the receiver is crucial to the performance of a room equating system.Using computer simulations and physlml measurements.the distribution of the low frequency sound eld is analyzed.A special analysis was car-led out to explore theuse of 2 microphone positions around the listenan position.This lead to the conclusion.that the position sesitivity is less when using 2 microphone positions compared to 1 microphone position.' _ vamplitude responses simulated in the +10 cm and -10 cm positions.
