If the temperature goes down, the speed of sound goes also down.
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.

What happen to the speed of sound as temperature increases?
Scroll down to related links and look at "Speed of sound - Wikipedia". Look at the table with "speed of sound c".
As air becomes warmer how does the speed of sound in air change?
If the temperature goes down, the speed of sound goes also down. 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.
Discuss effect of temperature on the velocity of sound?
Scroll down to related links and look at "Speed of sound - Wikipedia". There is a table of the effects of the temperature on sound. Don't say "velocity of sound", call it "speed of sound".
How fast is the speed of sound at an elevation of 20000 feet?
Forget the altitude. Care about the temperature!The speed of sound is dependent on the temperature and not on the air pressure of the altitude. At 20 degrees celsius or 68 degrees Fahrenheit the speed of sound is 343 m/s or 1236.3 km/h or 1126.7 ft/s or 667.1 knots.Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".Here is an easy calculator if you know the temperature. Do not care about the altitude!Scroll down to related links and look at "Calculation of the Speed of sound in air and the important temperature".Asume a temperature of -70 degrees Celsius for a height of 44,000 feet.
Do sound travels at low temperature?
Yes, but the speed of sound is slower then. The formula to find the speed of sound in air is as follows: c = 331 m/s + 0.6 m/s * T (°C) c is the speed of sound and T is the temperature of the air. One thing to keep in mind is that this formula finds the average speed of sound for any given temperature. The pitch of woodwind instruments and pipe organs goes down, when the temperature goes down.
What is the velocity of sound at sea?
Do you mean speed of sound at sea level? Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".
What is the speed of sound in air at sea level?
The speed of sound has nothing to do with the sound pressure, like "at sea level" or on top of a mountain. But the speed of sound has very much to do with temperature. Scroll down to related links and look at "Calculation of the Speed of Sound".
How does temperature affect the speed of sound through a material?
Temperature affects the speed of sound through material by kinetic energy. The more molecules the higher temperatures will have more energy.
Do sound waves increase or decrease above sea level?
The sound has really nothing to do with sea level, but changes with temperature alone. The speed of sound goes up when the temperature goes up and goes down when the temperature goes down. The frequency of sound columns, like of woodwinds or of church organs changes with temperature. If the temperature increases, the frequency increases also.
What affects the speed of sound through air?
It is an amazing fact that the speed of sound in air is a function of temperature only. Even very large pressure changes produce only very small changes in the speed of sound. The speed of sound in air is determined by the air itself. It is not dependent upon the sound amplitude, frequency or wavelength. Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".
Speed of sound in air at sea level?
The speed of sound in air changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary. Look at the link: "Speed of Sound in Air and the effective Temperature":
What Factors determinethe speed of sound?
The speed of sound changes only with temperature. The altitude and the atmospheric pressure has no influence. Usually the temperature goes down with higher altitude. Notice: The speed of sound changes with temperature and 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.
