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.

∙ 13y agoIn SI units with dry air at 20°C (68 °F), the speed of sound c is 343 m/s.
This also equates to 1235 km/h, 767 mph, 1125 feet per second (ft/s), or 666 knots.
There is no special name for the speed of sound at graound level, because the ground level and every other air pressure high up in the mountain has nothing to do with the speed of sound.

The temperature is important for the speed of sound.
At 20° Celsius the speed of sound is 343 m/s.

What is the Velocity of air at sea level?
The speed of sound in air has really nothing to do with the sea level and its atmospheric pressure. Speed of sound is dependent on the temperature. Look at the link: "Speed of Sound in Air and the effective Temperature".
How fast is the speed of sound on land?
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.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.
What is the speed of the wave called?
There is no special name for the speed of sound at sea level, because the sea level and every other air pressure high up in the mountain has nothing to do with the speed of sound. Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".There is no special name for it.By the way, the speed of sound has nothing to do with the sea level.The speed of sound has much to do with the temperature.At 20° Celsius the speed of sound is 343 m/s.
Does sound travels faster through air?
sound travels faster through water. it is also affected by temperature and sea level. the speed of sound or mach 1 is reached roughly around 744 MPH plus the Mass of the object that is traveling at that speed.
What factors affect the speed of sound in air?
The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.5 feet per second. 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.
What is the speed of sound at sea level for Tucson?
The speed of sound has neither to do with the sea level nor with Tucson. Speed of sound has mainly to do with the temperature of the air. Look at the link: "Speed of Sound in Air and the effective Temperature".
What is the Velocity of air at sea level?
The speed of sound in air has really nothing to do with the sea level and its atmospheric pressure. Speed of sound is dependent on the temperature. Look at the link: "Speed of Sound in Air and the effective Temperature".
The speed of sound in air is always close to?
The speed of sound at sea level is approximately 750 mph.
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 do the speed of light and the speed of sound compare through air?
The speed of light through air at sea level is roughly881 thousand times the speed of sound.
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".
State the speed of sound?
The speed of sound at sea level is 340.29 miles per second.
What is mach2?
Mach 1 is the relative speed of sound through air. Relative because the speed of sound varies with air density. At sea level the speed of sound is about 740 miles per hour. Mach 2 is then twice the speed of sound.
What is the equivalent estimate to the speed of sound?
The speed of sound is 331 metres per second at zero degree centigrade and at sea level (air pressure and temperature affect the speed of sound).
What is the speed of light and sound in mph?
Speed of light (in vacuum)= approx 671,000,000 mph.Speed of sound (in air at sea level) = approx 760 mph.
What is the average speed for a sound wave at sea level?
The speed of sound has nothing to do with the sea level. It has much to do with the temperature. At 20°C the speed of sound is 343 m/s.
How fast is the speed of sound at sea level?
761.207 mph at sea level.
