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.
What is the speed of sound at sea level on a standard day?
The speed of sound is normally calculated using the values of a "standard atmospheric day." A "standard atmospheric day" refers to a sea level pressure of 29.92 in-Hg (1013.2 mb) and a temperature of 15°C (59°F). At standard day values, the speed of sound is 761 mph. Other speeds, such as those presented below, use values other than those relating to a "standard atmospheric day." They are not incorrect, they are simply based on values other than a "standard atmospheric day."The speed of sound is 343 m/s or 1126.547 ft/s (768.095 mph) at a temperature of 20°C or 68°F.The speed of sound has nothing to do with the atmospheric pressure at sea level, but the temperature is very important.Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure".The air pressure and the air density are proportional to each other at the same temperature.The speed of sound c depends on the temperature of air and not on the air pressure!The humidity of air has some negligible effect on the speed of sound. The air pressureand the density of air (air density) are proportional to each other at the same temperature.It applies always p / ρ = constant. rho is the density ρ and p is the sound pressure.Notice: The speed of sound is alike on a mountain top as well as at sea level with the same air temperature.Google is not correct (look at the following link):http://www.google.com/search?q=speed+of+sound+at+sea+levelHere is the answer of Google: "Speed of sound at sea level = 340.29 m/s".This is no good answer, because they forgot to tell us the temperature,and the atmospheric pressure "at sea level" has no sense.The speed of sound in air is determined by the air itself. It is not dependent upon the sound amplitude, frequency or wavelength.
What is the speed of sound?
The speed of sound is the velocity of sound through a mechanical (elastic) medium (such as air, water, concrete, etc.). It will vary as the medium through which it travels varies. In general, the speed of sound is faster in liquids and even faster in solids.In air, the speed of sound has little to do with the atmospheric pressure "at sea level" or with the humidity, but the temperature is very important. Therefore we can set aside questions of altitude and humidity.The speed of sound in air is 343 m/s or 1126.547 ft/s (768.095 mph) at a temperature of 20°C or 68°FThe air pressure and the air density are proportional to each other at the same temperature.Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure" and "Calculation of the speed of sound".The speed of sound at sea level is equal to 340.29 metres per second.343 meters/second (1,125 ft/s) or 1,236 kilometers/hour (768 mph).This speed is variable, dependent on the air density (elevation), temperature, and humidity.Notice: The speed of sound changes with temperature anda 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 at 20 degrees Celsius (68 degrees Fahrenheit) is 343 meters per second.Speed of sound is 331m/s in Air Medium. It varies from medium to medium. It is highest in some crystals.340.29 m / sspeed of sound at sea level = 340.29 m/sIt is hard to be too precise as the speed of sound is affected by humidity. Over land the speed of sound is 331.3 m/s but slightly higher when the air is wet. Generally, the difference in seconds between the lightning and the sound of thunder is divided by 3 to get the distance of the lightning strike in kilometres.
What is the spead of sound at sea level called?
Forget the sea level. The speed of sound is dependent on the temperature and not on the air pressure. 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.

What is the speed of sound as it passes through air?
The speed of sound is dependent on the temperature and not on the air pressure. 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".At room temperature (20°C, 68° F) the speed of sound is 343 meters per second, 767 miles per hour, or 0.213 miles per second.Sound waves must have matter and/or molecules to travel. Where there is no matter, such as in outer space, sound cannot travel.At room temperature (20°C, 68° F) the speed of sound is 343 meters per second, 767 miles per hour, or 0.213 miles per second.Sound waves must have matter and/or molecules to travel. Where there is no matter, such as in outer space, sound cannot travel.At 20 degrees Celsius the sound travels in air 343.4 meters per second. That means in 1 second the sound travels 343.3 meters. In 2.912 milliseconds the sound travels 1 meter.Well it is really dependent on the temperature of the air, but in this case we will assume the standard temperature ( 20 degrees C) it travels at 343 meters per second.Through air, sound waves travel at 343 m/s
What is the speed of sound in a second?

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":
How fast does sound travel in a canyon?
The sound speed depends on the property of the material where sound travels, not from the far surrounding. Thus, if sound travels in air, the fact that it is in a canyon or not has no impact. Sound speed on the contrary depends on temperature and ono the presence of solutes in the gas (in the case of air for example on the air humidity). Sound speed in dry air at 20°C is 343.2 meters per second (1,126 ft/s).

Velocity in sound waves?
Usually we talk about speed of sound. Speed is the rate of change of distance with time. Velocity is a measure of both speed and direction of a moving object. Velocity is the rate of change of displacement with time. Speed is a distance an object goes, velocity is measurment of speed AND direction. Speed of sound at 20 degrees Celsius (68 degrees Fahrenheit) is 343 meters per second.
Two planes are flying at the speed of sound Plane X is flying at an altitude of 6000 feet and plane Y is flying at an altitude of 15000 feet which is flying faster?
As altitude increases (to about 35,000 ft) air density, pressure and temperature all drop. As density decreases speed of sound increases, but with drop in pressure it drops; these two practically cancel each other out. As temperature drops, speed of sound drops. Thus at 15,000 ft the speed of sound is slower than at 6,000 ft so plane X is flying faster than plane Y.
