How is intensity related to loudness?
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
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 Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity

How is the loudness of a sound related to the amplitude?
Loudness is really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.
What machine measures sound intensity?
The instruments are variously known as sound level meters, noise meters, noise dosimeters, acoustic transducers, etc.
Is intensity a property of sound?
Sound intensity is a property of sound.
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
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.
