Deep sound channel definition
WebThe SOFAR channel (short for Sound Frequency and Ranging channel), or deep sound channel (DSC), [1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before … WebDeep Sound Channel (DSC), also called the . Sound Fixing and Ranging (SOFAR) Channel. The channeling occurs because a sound wave turns, or is refracted, when one …
