![]() ![]() ![]() The better agreement of our results with those of Wilson may be fortuitous since our measurements were made relative to his pure‐water data. Over the oceanic range our results agree on the average with the work of Wilson to 0.3 msec −1 (maximum deviation 0.6 msec −1), and with the work of Del Grosso to 0.5 msec −1 (maximum deviation 0.9 msec −1). Sound 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. Our results agree with the work of Wilson on the average to 0.36 msec −1 over the range of 5 to 40 o/oo salinity, 0° to 30☌, and 0 to 1000 bars. where the speed of sound in seawater (C) is in meters per second, temperature (T) is in degrees Celsius, salinity (S) is in parts per thousand (), and depth (Z). Sound travels much more slowly in air, at about 340 meters per second, only 3 soccer fields a second. The speed of sound in water is almost 1500 meters per second, or over 3000mph.

That's approximately 15 soccer fields end-to-end in one second. This equation has been combined with the refitted high‐pressure pure‐water sound‐speed equation of Wilson, Chen and Millero, and the 1‐atm seawater sound‐speed data of Millero and Kubinski to calculate the speeds of sound for seawater at various salinities, temperatures, and pressures. How fast does it travel Sound travels about 1500 meters per second in seawater. It increases about 4.5 metres (about 15 feet) per second per each 1 C increase in temperature and 1.3 metres (about 4 feet) per second per each 1 psu increase in salinity. Calculates the speed of sound in seawater using the computationally efficient 75-term expression for specific volume in. The effect of pressure on the relative speeds of sound, ( U P− U P H 2O) ‐ U O− U O H 2O), have been fitted to an equation of the form (with a standard deviation of 0.19 msec −1) ( U P− U P H 2O) ‐ ( U O− U O H 2O) = A S (°/oo)+ B S (°/oo) 3/2 + C S (°/oo) 2, where U and U H 2 0 are the speeds of sound in seawater and pure water, respectively superscripts P and O are used to denote applied pressure P and O (1 atm) A, B, and C are temperature‐ and pressure‐dependent parameters S ( o/oo) is the salinity in parts per thousand. In the oceans the speed of sound varies between 1,450 and 1,570 metres (about 4,760 to 5,150 feet) per second. The speed of sound in standard seawater (diluted with pure water and evaporated) have been measured relative to pure water with a Nusonics single‐transducer sound velocimeter as a function of salinity (5–40°/00), temperature 0°–40☌, and applied pressure (0–1000 bars). ![]()
