Sound Reception Systems
Acoustical electronic navigational aid to enable the officer on the watch to hear warning signals from other vessels inside a totally enclosed bridge in order to perform the look-out function as required under COLREG 1972. The SRD 414/2 receives sound signals from all directions in the audio band 70 Hz to 820 Hz , reproduces the incoming sound signals inside the bridge, indicates the approximate direction of the incoming sound, and suppresses unwanted background noise thus allowing reception of meaningful sounds only.
