The Speed of Sound Calculator calculates the speed of sound in both air and water, taking temperature into account. To find speed quickly, simply enter the input temperature in the appropriate areas and click the calculate button.
Speed of Sound Calculator: Do you find it difficult to solve issues that need you to determine the speed of sound in air and water given certain temperatures? Don't worry; the Speed of Sound Calculator can give you all of the necessary information. Learn how to use simple formulas to compute the speed of sound in both air and water. You'll also study the relationship between sound speed and temperature in the following lessons.
Air is an ideal gas, the formula for estimating sound speed in air is as follows c = √(γ * R * T / M)
We can simplify the formula by putting the value in the air c_air = 331.3 * √(1 + T/273.15) [m/s] for T in °C
Have you noticed anything intriguing? The speed of sound in a gas is only affected by two constants - R and temperature - and not by air pressure or density, as some people believe. The speed of sound is also affected by air humidity, but the effect is so minor that it can be overlooked.
The most commonly cited value is 1482 m/s (at 20°C); nevertheless, there is no simple formula for the speed of sound in water.
Many writers used experimental data to construct equations, but the equations are difficult and always include higher-order polynomials and a large number of coefficients. The information in our calculator for water speed comes from charts of sound speed in the water. In sonar research and acoustical oceanography, the speed of sound in water is an essential characteristic. However, because the speed of sound changes with salinity, the formula for seawater is significantly more complicated.

Let's see how sound travels in cold water - like very cold water - as a result of winter swimming activities.
1. What is the sound speed in kilometres per hour?
The speed of sound at sea level on Earth is 761.2 mph (1,225 km/h) at a temperature of 59 degrees Fahrenheit (15 degrees Celsius). Sound travels slower in colder air because gas molecules move more slowly at lower temperatures; sound travels quicker through warmer air.
2. What is the speed of sound in a vacuum?
n a vacuum, the speed of sound is zero metres per second since there are no particles present. As a result, the vacuum speed of sound waves will be zero.
3. What time of day does sound travel at its fastest?
The sun heats the earth's surface during the day, warming the air near the ground. Warmer air allows sound to travel faster. As a result, sound travels quicker toward the ground in the air. At night, the situation is reversed.
4. Is the speed of sound affected by the temperature of the air?
Yes, according to Kim Strong, a physics professor at the University of Toronto, sound travels quicker when the air is hotter. At 25 degrees Celsius, sound travels at a speed of 1,246 kilometres per hour.
5. Is it true that all sound travels at the same rate?
The speed of sound does not always remain constant. In solids, sound travels quicker, but in liquids or gases, it travels slower. Two qualities of matter influence the velocity of a sound wave: elastic properties and density.
