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.

How many times louder is a sound wave with a intensity of 83db than a sound wave with an intensity of 70db?
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
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 scientific definition for intensity?
Intensity is proportional to the square of the amplitude of vibration in case of mechanical wave such as sound waves But in case of light which is electromagnetic in nature, the intensity is the number of photons crossing unit area in one second
What is the scientific definition of the word volume?
the magnitude or intensity of a certain sound

Measure of sound?
Sound intensity is measured in a increment called a decibel, and its characteristics are decribed in terms of its frequency , wavelength, and amplitude.
What is the name of sound intensity?
Sound intensity is mesured in decibels !
Sound intensity decreases when what decreases?
