Sound is measured in decibels, dB.
Ten decibels (one Bel) sounds twice as loud as another sound.
One decibel is the amount of sound just distinguishably louder than another sound.
Named after A G Bell of telephone fame.

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 is the unit of sound intensity?
Decibel
How is the intensity of sound measure?
You take a measuring microphone with a sound pressure level meter.
A decibel is a unit used to measure the?
decibels measure the intensity of sound.
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.
What unit of sound loudness?
The unit of sound loudness is the decibel (dB). It is a logarithmic scale that measures the intensity or volume of sound.
What is the intensity of a sound wave called?
The intensity of a sound wave is called sound intensity. It measures the amount of energy transmitted by the sound wave per unit area. Sound intensity is measured in decibels (dB).
What is the SI and CGS unit of sound?
The SI unit of sound is the decibel (dB), which measures sound intensity. In the CGS system, the unit of sound is the bel (B), where 1 bel is equivalent to 10 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 is the unit of sound and light?
Several units are used, depending on what you want to measure. For example, in the case of sound, you can use units of energy, of intensity (energy/area), of wavelength, frequency, speed, and probably a few more.
What units are used to express sound intensity?
Sound intensity is often expressed in decibels (dB), which is a logarithmic unit that measures the ratio of a sound's intensity to a reference intensity. Alternatively, sound intensity can also be expressed in watts per square meter (W/m^2).
What is the unit of sound intensity measurement?
The unit of sound intensity measurement is the decibel (dB).
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
Is sound intensity measured by a unit called Hertz?
No, sound intensity is measured in decibels (dB), not Hertz. Hertz is a unit of frequency, which measures how many cycles of a wave occur per second, whereas decibels measure the intensity or loudness of a sound.
What is the unit of sound measurement used to quantify the intensity of sound waves?
The unit of sound measurement used to quantify the intensity of sound waves is decibels (dB).
What is the measurement unit of sound?
frequency or velocity of sound.add. One measures the intensity (loudness) of sound in decibels dB.Harmonic Distortion is a measure of the frequencies in the sound complex other than the fundamental or original notes.
What is the unit of sound intensity?
Decibel
