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!

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.
Velocity of sound in Acetone is about 1174 m/s
the velocity of sound in the air is 300m/s
Velocity of Sound was created on 2002-10-08.
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.

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.

as density of medium increase velocity of sound decreases.
Sound velocity is greatest in solids, and the solid with the highest velocity of sound is metallic Beryllium.
Velocity of sound in air is 324m/s.
