A bel. Or a decibel which is an exponential measure such that 10 dB is one tenth as loud as 1 B.

Sound is a messure in what unit?

sound is measured in decibles


How is the intensity of sound measure?

You take a measuring microphone with a sound pressure level meter.


What is the unit for measuring the relative intensity or loudness of sound?

Loudness N is measured in in sones.Loudness level LN is measured in in phons.Sound pressure level is measured in dBSPL, where the reference level of 0 dBSPL is the threshold of hearing.The ear drums and the microphones are only sensitve to the sound pressure.We measure the sound pressure with a sound level meter.Loudness is affected by sound pressure, frequency and its bandwidth, and duration (time).Usually sound is measured in Decibels.


Unit of sound intensity?

The unit of sound intensity I is watts per meter squared (W/m²). Sound intensity is a sound energy quantity. Sound pressure deviations are moving our eardrums. The unit of sound pressure p is pascals (Pa) or newton per meter squared (N/m²). Sound pressure is a sound field quantity. Another answer: The most common unit of sound intensity is the decibel (dB). Reply: No! We got the sound intensity measured in W/m² and the sound intensity level we measure in decibels (dB). The question was "sound intensity".


What unit of measurement is used to compare the intensities of different sounds?

The unit is the decibel, based on a larger unit called a bel. The decibel is measured as a magnitude on a logarithmic scale, and has no dimension as such. An increase in the numerical value therefore indicates an exponential (logarithmic) increase in the actual intensity or power. Example : an increase of 3 dB is approximately twice the power, an increase of 10 dB is 10 times the power, and an increase of 20 dB is 100 times the power.
