Title:
BROADCAST UNIT AND VOICE OUTPUT CONTROL METHOD FOR THE SAME
Document Type and Number:
Japanese Patent JP2014232976
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform effective sound volume control even when a plurality of systems for controlling the output sound volume of a speaker depending on the magnitude of a noise are adjacently installed.SOLUTION: In a broadcast unit, a synthesis section generates a composite correction signal from a signal indicating the output sound volume of the broadcast unit, and a signal indicating the output sound volume of another unit and input via a communication line. A sound volume correction signal generation section generates a sound volume correction signal from the composite correction signal and a signal indicating detected sound volume detected by a microphone. The output sound volume is controlled by a broadcast signal amplifier and the sound volume correction signal.
