WebSound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air. Temperature … WebSound behaves differently in water than in air. Water is a liquid and non compressible. We tend to think of sound being 20-20,000Hz in air. That is because that is what we can hear. Bats and other nocturnal critters can extend that into the 100Khz plus range, which they mostly use for echolocation. In the water, sound waves go from about 10Hz ...

WebThe decibel value thus has a reference level of units "Volt/Pascal", or in underwater convention "V / μ Pa". A typical hydrophone may have a value of Mv peaking around 50 / μ V/Pa, but the corresponding decibel level then becomes -206 dB re 1 V / μ Pa. These extremely negative decibel levels can cause confusion, which is ironic given that the …
