Abstract

PURPOSE:To prevent sound interference in a concert hall, by transmitting sound signals such as music on a weak electromagnetic wave, receiving the said electromagnetic wave with a receiver of each listner, so that each listner can enjoy the music with a headphone. CONSTITUTION:On a stage 2 of a concert hall, a tape player 3 and a record player 4 are provided, electric signal from them and an audio signal from a commentator are mixed with a mixer 7 and are supplied to a transmitter 10, where an electromagnetic wave with a prescribed frequency and a weak output is transmitted from an antenna 10(15muV/100m). On the other hand, each listner carries its receiver 13, takes a seat as the desires, the said transmitted electromagnetic waves are received to enjoy the music with a headphone 13a. An electric field strength monitoring device 14 is provided around the concert hall, if the electric field is a prescribed value or over, an output adjusting device 15 is controlled to lower the transmission output.
