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".

∙ 12y agoSound waves are a little part of the atmospheric pressure in air.
The instantaneous sound pressure is the deviation from the local ambient pressure po caused by a sound wave at a given location and given instant in time.

∙ 13y agoUsual variation in air pressure does not change the audibility of sound.

of the sound's source. It's not affected by air pressure.

When cycling what forces can effect you?
tension , compression and friction
What effect temperature have on tire behaviour?
i can effect the pressure and make gripping difficult
How do particles change over time?
this is bcos,they get constantly subjected to friction,pressure,temperature which has drastic effect on their size and shape and after a long period of time their properties get changed.
What effect does cold air have on air pressure?
Cold air increases air pressure
What is the effect on pressure of doubling the surface area on which a force is being exerted?
pressure will be halved
What is the area of compression and rarefaction?
Compression is a Pushing Force whereas Rarefaction is a Pulling Force[Compression is the point when the most force is being applied to a molecule&Rarefaction is the point when the least force is applied].Compression happens when particles are forced/pressed together.Rarefaction is just the opposite,it occurs when particles are given extra space&allowed to expand.Compression&Rarefaction are Effects the wave causes.If you look at any normal visual representation of a Sound Wave,the humps above the middle line are called Compressions,the humps below are called Rarefactions.
What physical effect can change the boiling of substance?
Pressure
How does barometric pressure change effect wind speed?
cause.
What is refrigeration effect?
When you plot a system on a mollier diagram it the point between the pressure drop and the bottom of the compression line, measured in BTU/LB. Also known as the Net Refrigeration Effect.
Can low compression affect timing?
No. Low compression does not effect timing but timing can affect compression.
What is the effect of temperature change on the pressure of a contained gas?
When temperature increases, pressure also increases.
Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
No.
What is tension and compression?
Tension and compression takes place when an object has a force on another object. The tension is when the force is causing a pulling effect on part of the object. The compression is when the force is causing a contracting effect on part of the object.
In the body what kind of change in the cardiovascular system would have the same effect as pressure?
Retention of water.
How does someones blood pressure stay the same with out eating?
Eating does not typically have any effect on blood pressure. So there shouldn't be any change.
Why does CPR have to be done on the floor?
CPR has to be done on a hard surface or else the pressure of the compression continues through the body and into the soft surface beneath (such as a bed), which has no effect on circulating blood or oxygen.
How do you measure pressure and what effect does it have on our weather?
on a pressure meter it has no effect
