Long Range Acoustic Hailing System

DSPPA Long Range Acoustic Hailing System is a breakthrough hailing and warning, directed acoustic device designed to communicate with authority and exceptionally high intelligibility.
What makes the DSPPA product unique is its ability to transmit messages with exceptional voice intellgibility and tonal clarity in a highly directional beam, even with significant ambient noise. The directionality of the acoustic hailing device reduces the risk of exposing nearby personnel or peripheral bystanders to harmful audio levels. DSPPA Speakers can be used in all weathers by the high quality materials.
