![]() ![]() For example, the sound travels in water 4.3 times faster than in air, in glass 13 times faster than in air, and in diamond, it travels 35 times faster than in air. It travels faster in liquids and even faster in solids. Therefore, the entry of both temperature and unit designation is required for the calculation. It is inversely proportional to the frequency of the wave if we assume that the wave is moving at a fixed speed.Īt 20 ☌ or 68 ☏, the sound is traveling in dry air at about 343 meters per second or 1125 feet per second or a 1 kilometer per approximately 3 seconds. The density of the air is dependent on the temperature of the air. ![]() The wavelength is the distance over which the wave’s shape repeats. The period is the duration of time in one vibration or cycle and is measured in seconds. Speed of Sound in Air is Calculated by performing the square root of product of coefficient of adiabatic expression and pressure of gas divided by density of. The number of these vibrations per second is called the frequency, which is measured in hertz. Speed of sound temperature calculator - Check with our speed of sound calculator how the speed of sound in water or air changes with temperature. Measuring the speed of sound in air Aim To measure the speed of sound. Therapeutic ultrasound 6 - Non-destructive testing and medical ultrasound diagnostics 7 - Acoustic microscopy 8 - Infrasound 9 - Human hearing range 10 - Ultrasound The speed of sound in air, at sea level, at a temperature of 21 and under normal atmospheric conditions, is 341 m·s 1. 767.3 miles per hour (mph), 12.79 miles per minute (mi/min), 0.2131 miles per second (mi/s). ![]() This also equates to 1235 km/h, 767 mph, 1125 feet per second (ft/s), or 666 knots. 1 - Earthquakes, lightning and nuclear detonation detection 2 - Acoustic sound 3 - Animal hearing 4. In SI units with dry air at 20C (68F), the speed of sound c is 343 meters per second (m/s). ![]()
