What is temperature pressure?
Notice for musicians and technicians (not for physics professors):
The speed of sound 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. The temperature indication, however, is absolutely necessary. The changing of atmospheric pressure does not change the sound of Musical Instruments in a concert hall or in a room.

What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
Is sound produced when there are increases in pressure or oscillations in pressure?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with 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".
What is the effect of temperature on velocity of sound?
Formula for speed of sound c = 331 + 0.6 × ϑ ϑ = temperature in degrees celsius. At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s. 1 °C change of temperature is equal to 60 cm/s change of speed of sound. The speed of sound 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. The changing of atmospheric pressure does not change the sound of musical instruments in a concert hall or in a room. Look at link: "Temperature Dependence of Physical Entities".
What is the speed of sound at standard temperature and pressure?
330 m/s
Speed of sound in miles per second?
About 0.213 in air at standard temperature and pressure.
What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
What is the relationship of speed of sound to the atmospheric pressure?
There is a relationsship of speed of sound to the temperature but not to the atmospheric pressure.
Is sound produced when there are increases in pressure or oscillations in pressure?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
How did pressure effects the sound when temperature is constant?
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
About how fast is the speed of sound in air?
The speed of sound 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.Formula for speed of sound c = 331 + 0.6 × ϑϑ = temperature in degrees celsius.At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s.1 °C change of temperature is equal to 60 cm/s change of speed of sound. When calculating the speed of sound forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height or elevation) only because of the changing temperature there!Look at the link: "Speed of Sound in Air and the effective Temperature".
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.
How does pressure affect sound wave propagation?
Only the temperature is changing the speed of sound.
What is the speed of sound in medium as the pressure of medium increase?
The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure). Speed of sound c = 331.3 + 0.606 × ϑ At the temperature ϑ = 20°C the speed of sound is c ≈ 331 + (0.6 × 20) = 343 m/s.
