The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature. The ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude.
That means, the ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant.
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) only because of the changing temperature there.

What else can I help you with?
What is the effect of pressure and speed in sound waves?
Speed affects the frequency and pressure affects the wavelength.
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.
What is the speed of sound in m?
It's about 340 m/s. Temperature, pressure, and humidity all have an effect on the exact speed.
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.
What is the effects of variations of pressure on the speed of sound in gase?
The speed of sound in a gas is influenced by variations in pressure, but primarily depends on the gas's temperature and molecular composition. In an ideal gas, when pressure increases at a constant temperature, the speed of sound remains relatively unchanged because both density and stiffness increase proportionally. However, at constant pressure, an increase in temperature results in a higher speed of sound due to reduced density. Thus, while pressure changes alone have a limited direct effect, they interact with temperature to influence sound speed.
What happens to speed of sound in air when sound get louder?
The loudness of the sound has no effect on its speed.
What is the effect of pressure o the speed of sound?
The air pressure has no effect. The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature. The ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude. That means, the ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant. 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) only because of the changing temperature there.
How does air pressure change the effect of sound waves compression and rarefaction?
Air pressure does not affect transverse sound waves. The temperature is most important to do that. The speed of sound in air is determined by the air itself and is not dependent upon the amplitude, frequency, or wavlength of the sound. Look at the link: "Speed of Sound in Air and the effective Temperature".
Why is the speed of sound independent of pressure?
The speed of sound is independent of pressure because changes in pressure do not significantly affect the density of the medium through which sound waves travel. Sound waves rely on the elasticity and inertia of the medium, rather than its pressure, to propagate at a constant speed.
Did pressure greatly affect the peed of sound in the air?
No. Speed of sound is independent of pressure.
Does the speed of the sound change from medium to medium?
Dependence of the speed of sound on the properties of the medium: The speed of sound is variable and depends mainly on the temperature and the properties of the substance through of which the wave is traveling. For example, in low molecular weight gases, such as helium, sound propagates faster compared to heavier gases, such as xenon. In a given ideal gas the sound speed depends only on its temperature. At a constant temperature, the ideal gas pressure has no effect on the speed of sound, because pressure and density (also proportional to pressure) have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly. In non-ideal gases, such as a van der Waals gas, the proportionality is not exact, and there is a slight dependence on the gas pressure, even at a constant temperature. Humidity also has a small, but measurable effect on sound speed (increase of about 0.1% to 0.6%), because some oxygen and nitrogen molecules of the air are replaced by the lighter molecules of water.

What does high pressure do to sound?
High pressure can increase the speed of sound transmission and alter the frequency of sound waves. It can also affect the way sound is perceived by the human ear, potentially causing discomfort or distortion in hearing.
