Compressional waves caused by colliding air molecules?
Yes indeed, Sound waves will have alternate compression and rarefaction pressures. The air pressure goes above and below the average air pressure.
A sound waves amplitude corresponds to the sounds what?
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
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".
How does the sound of a banjo travel through the air?
As vibrations, pressure waves.
Are sound waves the moving areas of high and low pressure?
Sound waves don't change with high or low pressure, but with temperature, because then the speed of sound is changing. Look ath the link: "Speed of Sound in Air and the effective Temperature".
How are sound waves sensed?
Sound is vibration that propagates to be a audible mechanical wave. It uses pressure and displacement, through air or water to be sensed whether by hearing or feeling.
What is downward displacement of air?
Downward displacement of air happens when you fill the upper part of a pressure chamber with steam. This causes the denser air below to move downward.
What is a positive displacement air compressor?
An air compressor which is used to compress air in a cylinder, that is reducing the volume and increasing the pressure of air is known as positive displacement air compressor. It is used for the compression process in IC engines.
Compressional waves caused by colliding air molecules?
Yes indeed, Sound waves will have alternate compression and rarefaction pressures. The air pressure goes above and below the average air pressure.
What part of a trumpet vierbrates to make a sound?
This is a matter of discussion. Your lips are used to set up a sinusoidal pressure wave in the trumpet, but nothing in the trumpet tubing vibrates to produce the sound. Modern testing shows that the pressure forms into "standing waves" which produce the sound when they hit the bell area where the standing waves are amplified to reproduce the pressure waves again.
What causes the sound that come from the voices?
Pressure waves in the air.
Why are sound waves known as pressure waves?
Because it is pressure that actually propagates through the medium. When air is the medium, air molecules are displaced outward and then back, in unison with the sound generating object. This 'wave' of pressure, much like a ripple on water, moves through the air outward from the source.

How is sound created on the guitar?
When a guitar string is plucked, it vibrates. The vibration of the string causes pressure waves in the air. The pressure waves are called "sound".
Sound waves travel through what layer of the atmospherer?
A sound wave is the rapid compression and expansion of air pressure that "waves" outward from where it first originated. As the pressure of the surrounding air decreases, the amplitude seemingly decreases. Sound waves travel through all layers of the atmosphere but do not travel through space where there is no air and zero pressure.
Is a standing wave a wave?
The modes of vibration associated with resonance in extended objects like strings and air columns have characteristic patterns called standing waves. Scroll down to related links and look at "Strings, standing waves and harmonics".
