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.

∙ 14y agoNotice: 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.

∙ 13y agothe 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.

∙ 12y agoSpeed 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.

How does the speed of sound in air compare to the speed of sound in solid?
The speed of sound in a solid is faster than the speed of sound in air.
Which is faster the speed of sound or the speed of air?
The speed of sound depends on the air factors around it
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases
Which is faster the speed of sound in air or the speed of light in air?
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Why is the speed of sound in air faster than the speed of sound in solid?
its not
When the temperature is 25 degrees Celsius what is the approximate velocity of a sound wave traveling through the air?
The approximate speed of sound in air at 25°C is 346.45 m/s².
What speed does sound travel through a gas?
Sound travels through each medium (and each gas) at different velocities.In air, sound travels at an approximate speed of 330 m/s.Factors such as temperature and humidity also affect the speed of sound.
How does the speed of sound in air compare to the speed of sound in solid?
The speed of sound in a solid is faster than the speed of sound in air.
How does the speed of sound in steel compare with the speed of sound in air?
The speed of sound in steel is faster than the speed of sound in air.
What is the approximate velocity of the sound in air?
the velocity of sound in the air is 300m/s
What is the approximate velocity of sound in the air?
the velocity of sound in the air is 300m/s
The pitch of a sound is determined by its wavelength and what?
only wavelengthActually, since ultimately the pitch we hear depends on the frequency, and the frequency is equal to the speed of sound divided by the wavelength, the pitch depends on both the wavelength and the speed of sound. The speed of sound in air depends on the temperature of the air. An approximate formula for calculating the speed of sound (credit Wikipedia) is:cair = 20.0457 x sqrt( T ) m/swhere T is the kelvin temperature.

Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Why is the speed of sound in nitrogen similar to the speed of sound in air?
This is because air is 78% nitrogen.
The speed of sound in a solid is what than the speed of sound in air?
greater
