Abstract
A sound enhancement system is configured such that sound emitting and collecting apparatusestoare connected to each other via a transmission line LT. The sound emitting and collecting apparatusestoare grouped into a master and a slave. The master sound emitting and collecting apparatusgenerates a reference clock signal to be supplied to slave sound emitting and collecting apparatusesto. The slave sound emitting and collecting apparatusestoform a sound collection beam signal in synchronization with the reference clock signal, and then output the resulting signal to the master sound emitting and collecting apparatuswithout performing acoustic coupling suppressing process. The master sound emitting and collecting apparatuscollectively executes the acoustic coupling suppressing process to each sound collection beam signal to produce a sound emitting signal. The master sound emitting and collecting apparatusoutputs the sound emitting signal to the slave sound emitting and collecting apparatusesto, each of which emits sound based on the sound emitting signal.
