Formula for speed of sound c = 331 + 0.6 × ϑ
Ï‘ = 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 ratio p_ / Ï is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air Ï 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 or elevation) only because of the changing temperature there!

What else can I help you with?
What are the factors that affect the velocity of sound in a gas?
The velocity of sound in a gas is affected by factors such as the temperature, pressure, and density of the gas. In general, sound travels faster in gases with higher temperatures, higher pressures, and lower densities.
When was Velocity of Sound created?
Velocity of Sound was created on 2002-10-08.
Is velocity of ultrasonic sound depends on density?
No, the velocity of ultrasonic sound in a medium is primarily influenced by the elasticity and the compressibility of the medium. Density does not have a direct impact on the velocity of ultrasonic sound but can indirectly affect it through its relationship with the elastic and compressible properties of the medium.
Why velocity of sound depend upon nature of medium?
The velocity of sound depends on the nature of the medium because the properties of the medium, such as its density and elasticity, determine how quickly sound waves can travel through it. In general, sound travels faster in solids than in liquids, and faster in liquids than in gases, because solids have higher density and elasticity compared to liquids and gases. Additionally, the temperature of the medium can also affect the velocity of sound.
Does velocity effect rate of fall?
That's like asking "Does the loudness of a sound affect its amplitude ?", or"Does the number marked on the tag affect the item's price ?"The rate of fall IS the magnitude of the velocity.

What three things affect the frequency of a sound wave?
The three things that affect the frequency of a sound wave are the source of the sound (vibration frequency), the medium through which the sound wave is traveling (speed of sound in the medium), and the relative motion between the source of the sound and the observer (Doppler effect).
What is the approximate velocity of the sound in air?
the velocity of sound in the air is 300m/s

Stream velocity does it have anything to do with discharge of stream or stream elevation?
Stream discharge physically depends on two factors: stream cross-sectional area and velocity. Area is composed of width and depth. Q (flow) = vel x width x depth. Stream elevation change, or how steep a stream is, will affect the velocity. Higher sloping streams (like those with few meanders) will travel faster than sinuous, snaking streams that have a lower elevation drop per length of stream.
Is velocity of ultrasonic sound depends on density?

Density does not have a direct impact on the velocity of ultrasonic sound but can indirectly affect it through its relationship with the elastic and compressible properties of the medium.

Is Sound listen greater in solids or in air?
Sound velocity is greatest in solids, and the solid with the highest velocity of sound is metallic Beryllium.
Give the effect of density on velocity of sound?
As density increases, the velocity of sound increases because there are more particles for the sound wave to travel through. Conversely, if the density decreases, the velocity of sound will also decrease because there are fewer particles for the sound wave to travel through.
The velocity of a sound wave travel though the air is approximately?
Velocity of sound in air is 324m/s.
