How fast does it travel? Sound travels about 1500 meters per second in seawater. That's approximately 15 football fields end-to-end in one second. Sound travels much more slowly in air, at about 340 meters per second, only 3 football fields a second. Unfortunately, the answer is really not quite that simple. The speed of sound in seawater is not a constant value.
The actual speed of sound varies depending on the altitude above sea level because sound travels at slightly different speeds at different temperatures and the temperature varies according to altitude. At sea level, the speed of sound is about 761 miles per hour (1,225 kilometers per hour). At 20,000 feet (6,096 meters), the speed of sound is 660 miles per hour (1,062 kilometers per hour). The speed of sound is commonly refered to as Mach 1, named after the 19th century Austrian physicist Ernst Mach [for biographical details click here].
