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. So we measure the sound with a SPL meter (Sound Pressure Level).

The intensity of light waves is a measure of what?
The intensity of light waves is a measure of the energy that is carried by the waves. Light waves are electromagnetic waves.
What is DBI in?
DBI refers to a decibil level, which is used to measure the power and intensity of sound waves.
The measure of a waves intensity?
The measure of the intensity of a wave is referred to as its amplitude.
What decreases when the intensity of sound decreases?
The amplitude of the sound waves decreases as the intensity decreases.
What causes sound waves?
intensity
A measure of a waves energy?
Intensity
How the term intensity decibel and amplitude are related?
They are all measueres of sound waves. Amplitude is the term for the maximum difference in pressures between the peaks and troughs of a sound wave. Intensity is a measure of the energy content of a wave, and is proportional to amplitude squared. The decibel is an anthropic (based on human senses) measure of sound intensity, proportional to the logarithm of intensity.
What is the measure of the intensity in sound waves?
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 (measured in W/m²). Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity (measured in pascals Pa). So we measure the sound with a SPL meter (Sound Pressure Level) in decibels.
What is intensity as it relates to sound waves?
Amplitude.
What machine is used to measure sound waves?
what machine can be used to measure sound waves
What is the amplitude of a sound wave a measure of?
The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.
How loud a sound seems is determined by what measurement of the sound waves?
Loudness is determined by the amplitude of the sound waves.
