(oceanservice.noaa.gov/facts/sound.html) states sound travels about 1,480 m/s in water versus about 343 m/s in air, because water is denser and far less compressible than air, allowing pressure waves to propagate faster., noaa national ocean service, how far does sound travel in the ocean? https://oceanservice.noaa.gov/facts/sound.html, noaa national weather service / britannica acoustics reference: speed of sound in water (~1480 m/s) is roughly 4.3x the speed of sound in air (~343 m/s), noaa national weather service / general physics reference: sound speed in air at 20c is ~343 m/s, while sound speed in fresh water at 20c is ~1482 m/s, roughly 4.3x faster due to water's higher bulk modulus and density ratio., noaa national weather service / general physics reference: speed of sound in air ~343 m/s at 20°c vs. speed of sound in water ~1480 m/s at 20°c, noaa national weather service / nist physical reference data: speed of sound in air at 20°c is ~343 m/s, and speed of sound in fresh water at 20°c is ~1480 m/s (standard acoustics physics references, e.g. nist speed of sound tables and noaa ocean acoustics fact sheet), noaa national weather service jetstream - speed of sound (https://www.weather.gov/jetstream/sound): 'sound travels faster in water than in air... in dry air at 20°c, sound travels at 343 m/s, while in fresh water at 20°c it travels at about 1,480 m/s.', noaa national weather service, 'speed of sound': sound travels at approximately 343 m/s in air (20°c) and approximately 1480 m/s in water, confirming sound travels faster in water than in air., noaa ocean explorer / nist physical acoustics reference: speed of sound in water is approximately 1480 m/s versus approximately 343 m/s in air at 20°c, because water's much higher bulk modulus more than offsets its higher density in the formula v = sqrt(b/rho), oceanservice.noaa.gov, pmel.noaa.gov, sanctuaries.noaa.gov, standard physics reference (e.g. nist/crc handbook of chemistry and physics, speed of sound tables): speed of sound in water at 20c is approximately 1480 m/s, versus approximately 343 m/s in air at 20c, so sound travels faster in water than in air., standard physics reference values (e.g. nist/crc handbook of chemistry and physics): speed of sound in dry air at 20c, sea level is ~343 m/s; speed of sound in fresh water at 20c is ~1480 m/s. 1480 > 343, so sound travels faster in water than in air., standard physics reference values for speed of sound: ~343 m/s in air at 20°c vs ~1480 m/s in fresh water at 20°c (e.g., nist/crc handbook of chemistry and physics acoustic property tables), confirming sound travels faster in water than in air.
