The speed of sound is the distance that sound waves travel through a medium (such as air, water, or solid materials) in a given period of time. In general, the speed of sound varies depending on the medium through which it is traveling, as well as environmental conditions such as temperature and pressure. In air at sea level and at a temperature of about 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound is approximately 343 meters per second (1,125 feet per second).
