# What is the formulae for finding amplitude of sound?

###### Wiki User

Amplitude= velocity/frequency

Sound velocity is known for many materials, e.g., air

The frequency changes, according with: high voice - high frequency (low

amplitude) and vice versa

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 &minus; the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement &xi;, 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 &Delta; 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?"

The amplitude(a) is the height of a crest or the depth of a trough measured from the undisturbed position of what is carrying the wave. +++ There isn't a formula as such, just the definition the first answer gives, though there are formulae for the amplitude related to other values in specific circumstances.

The amplitude is related to the loudness of the sound.

There is not only "one" amplitude. There is an amplitude of particle displacement &xi;, or displacement amplitude, an amplitude of sound pressure p or pressure amplitude, an amplitude of sound particle velocity v, or particle velocity amplitude, an amplitude of pressure gradient &Delta; p, or pressure gradient amplitude. If the "sound" inceases, the "amplitude" also increases.

Amplitude is typically represented as being the "height" of a sound wave. A sound that is louder will have a greater amplitude than a quieter sound.

The amplitude of a sound wave is a measure of its loudness. A loud sound will have a higher amplitude.

Amplitude is the maximum displacement of a wave. The amplitude determine the loudness of the sound

Loudness is a function of the sound wave's amplitude of the sound pressure.Amplitude is the volume of the sound (how loud it is).

The amplitude of a sound corresponds to its loudness so an increase in amplitude will correspond to a louder sound.

The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.

As we increase the amplitude then intensity of sound increases. The physical term is intensity. Practically we mean it as loudness. More amplitude then loud sound. If amplitude is less then sound is so soft.

The amplitude of a sound wave is interpreted as volume.

More amplitude means more loudness of the sound.

Amplitude relates to sound by being a height of the wave

The amplitude of the sound waves will be largerbecause the larger the amplitude the louderthe sound.

Amplitude is the maximum extent of vibration of a body from its mean position. The amplitude of a sound wave indicates the loudness of the sound.

When you increase the amplitude in sound it makes the sound louder. When you increase the amplitude in light it makes the light's intensity brighter.

The greater the amplitude of a sound wave the louder the sound.
