Noise levels of sound in the air are measured by a sound pressure level meter (SPL meter).
Noise levels in an electronic circuit are measured by a volt meter.

If you're asking for literally "how" it's measured, there are sound meters that basically use a microphone to turn sound into an electrical impulse, and then measure that. Properly calibrated, these read out the sound pressure level (usually, as mentioned above, in dB).

What noise is measured in?
Decibels
Is noise pollution measured in decibels?
Yes it is.
Is noise a source of pollution?
yes, and it is measured in decibels
The amount of thermal noise is measured by?
Decible(dB)
What is a noise level of 65 decibels measured for?
Normal speech
How do you measure the noise of a fan?
The noise of a fan can be measured in decibels using a sound pressure level meter. Knowing the level of noise allows people to classify as pollution or conducive.
A vessel may not be operated on Washington waters if when measured from the shore it produces a noise level over what decibel level?
A vessel may not be operated on Washington waters if, when measured from the shore, it produces a noise level over 75 decibels.
Systolic is measured at which korotkoff?
The systolic pressure is measured at the first Karotkoff sound (stage I), it is the first tapping noise that you hear with a stethoscope when taking a manual blood pressure.
A noise level of 65 decibels is measured for?
A noise level that measures 65 decibels is for a normal conversation on the noise scale. On this scale, 0 decibel is the threshold of hearing and 140 decibels is a jet plane at a distance of about 50 meters away.
How is sound level measured. At what level does sound become noise?
Sound level is measured in decibels (dB) using a sound level meter. Sound becomes noise when it is unwanted or excessive, typically around 85 dB for prolonged exposure or 120 dB for instant damage. Noise can also be subjective, as what is considered noise can vary from person to person.
What does CINR mean?
Carrier to Interference plus Noise Ratio, it's a measure of "true" signal strength at a receiver. In SNR, simply the signal strength to noise is measured; in CINR, distortions caused by interference patterns is also taken into account.
What is the name of the instrument used to measure noise pollution?
Air pollution may be due to:particulate matter by different sizesodourhazegaseous substancesThese materials can be measured by various monitors using samples taken at the site and measured by:local sensors/monitorslight absorption and refractionhuman observation (organoleptic observation) by trained observersNoise pollution involves sound measurement of:continuous noisesimpact frequenciespeak frequency identification
