Abstract

PURPOSE: To ensure the clear listening of the voice or the like by measuring and detecting the temperature, the velocity and the direction of the wind via the thermometer and the wind meter and thus setting up the time difference to the broadcast signals to be supplied to each speaker.
CONSTITUTION: Both the temperature of the wind measured through thermometer 4 puls the velocity and the direction of the wind measured through wind meter 5 are converted into the electric signals via converter 6 and 7 respectively to be then supplied to control means 8. At the same time, the signals to be broadcasted through speakers 1 and 2 are also supplied to means 8 via microphone 9 and the like. At the control part, the broadcast signals are mixed with adjustment with the control electric signals based on the temperature, velocity and direction parameters of the wind each, and the time difference is set up for the broadcast signals to be supplied to each speaker. Thus, the voices sent through speaker 1 and 2 feature the proper time difference to avoid the nonaudible or hard-to-listening states.
