What is the approximate speed of sound in the air?

Answer 1

The speed of sound, through air, at STP is: 331 m/s.

Related Information:

The speed of sound changes, most with temperature, slightly with humidity, and slightly with atmospheric pressure because air is not an ideal gas. Pressure has no effect on sound speed in an ideal gas.

The speed of sound in dry air, at 20 degrees Celsius (68 degrees Fahrenheit), is 343 meters per second, or 1126 feet per second.

Answer 2

Notice: The speed of sound changes with temperatureand

a little bit with humidity − but not with air pressure (atmospheric pressure).

The words "sound pressure at sea level" are incorrect and misleading.

The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second.

Answer 3

the speed of sound in air varies depending on temperature, altitude and air density. it is between about 300-350 m/s. it's faster in higher temperatures and lower air density.

Answer 4

Speed of sound in air is c ≈ 331 + 0.6 × T.

T = Temperature in °C.

Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

Answer 5

The speed of sound in air at room temperature is approximately 343 meters per second or 1,235 kilometers per hour. It can vary slightly depending on factors like temperature and humidity.

Answer 6

Approximately 770 miles per hour.
