Sound intensity or acoustic intensity (I) is defined as the sound power Pac per unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity.

What is volume mean in music?
Intensity of sound
Is intensity a property of sound?
Sound intensity is a property of sound.
What happens to the volume of a sound wave as its amplitude decrease?
You mean by the word 'volume' the intensity of sound wave. Intensity is directly proportional to the square of the amplitude.
What is the name of sound intensity?
Sound intensity is mesured in decibels !
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
Intensity of a sound?
Sound intensity or acoustic intensity(I) is defined as the sound power Pacper unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What is intensity of sound?
The sound intensity I or acoustic intensity is defined as the sound power per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What describes the intensity of sound?
Sound intensity or acoustic intensity is defined as the sound per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
What is intensity in sound?
Sound intensity (I) is a sound energy quantity in oposite to sound pressure (p), which is a sound field quantity. I = p². Sound intensity or acoustic intensity I is defined as the sound power Pac per unit area A. That is: I = Pac / A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What is the meaning of intensity in sound?
The sound intensity I or acoustic intensity is defined as the sound power per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location.
What is meant by the intensity of a sound?
The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity.
What is the minimum intensity a sound can have?
The minimum of sound intensity can be theoretically as low as zero decibels. But you seem to mean what the human threshold of hearing is. That reference sound intensity is 10^−12 W/m² equal to 0 dB sound intensity level. Our eardrums are moved by the sound pressure. The reference sound pressure at the human threshold of hearing is po = 20 µPa equal to 0 dB sound pressure level (SPL).
