Application in large transport terminals
Long-range loudspeaking equipment has a set of functions required to transmit information over large areas under conditions of high noise level.

The same difficulties occur in sea ports when a ship goes in a narrow passage, moors, etc. Application of conventional loudspeaking devices does not always thrive.
