Abstract

The invention aims to provide a loudspeaker array radiation automatic control method and device. The loudspeaker array radiation automatic control method comprises the steps that the moving speed of a person entering a loudspeaker array is collected; sound waves emitted by the loudspeaker array are controlled to move in the moving direction of the person entering the loudspeaker array according to the moving speed, and the moving speed of the sound waves emitted by the loudspeaker array is larger than the moving speed of the person entering the loudspeaker array; and when the loudspeaker array moves, an alarm is given. The sound wave emitted by the loudspeaker array is controlled to move towards the moving direction of the person entering the loudspeaker array according to the moving speed, the moving speed of the sound wave emitted by the loudspeaker array is greater than the moving speed of the person entering the loudspeaker array, and the alarm signal is emitted to remind the person that the person enters the dangerous area. Therefore, the use safety degree is improved.

Description

technical field [0001] The invention belongs to the field of directional loudspeaker equipment, and in particular relates to a loudspeaker array radiation automatic control method and device. Background technique [0002] Directional strong sound equipment is an efficient long-range sound wave directional emission device. It uses high sound pressure level transducer arrays to realize long-distance directional transmission of high-intensity sound waves, and effectively drives potential threats to birds through high-intensity noise stimulation. Leave. In addition, because the sound waves emitted by the strong sound directional equipment are directional, the sound in the forward area of ​​the equipment is clear and the attenuation is low, and the sound attenuation in the backward and surrounding areas is rapid, with little interference, and will not cause additional noise pollution to the airport. [0003] However, due to the high sound level and long distance of the direction...
