What is Ultra-high Frequency Long-range Acoustic Hailing Device?
It is a special acoustic equipment generating ultra-high sound pressure, mainly used for long-distance voice broadcast, directional acoustic deterrence and safety warning in special scenarios.
• Ultra-high Sound Pressure Level: Its output sound pressure far exceeds ordinary speakers, generally above 120dB and over 150dB at close range.
• High Directivity: Highly concentrated sound energy forms narrow acoustic beam to realize precise long-distance projection and reduce diffusion loss.
• Special Application: Besides information broadcasting, it is widely applied in non-lethal crowd dispersion, crowd control and regional security management.
