How is sound level measured. At what level does sound become noise?

Sound level is measured in decibels (dB) by a sound pressure level meter (SPL meter).
There isn't really a specific level at which "sound" becomes "noise." "Noise" is a somewhat subjective term for "sound that I do not want to hear"; for example, if rap music is at all audible, I personally consider it "noise" though my son does not.
In signal processing, "noise" means "anything that is not a deliberate signal" and generally has a significantly lowerdB level than the signal does.

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.

How is noise measured?
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.
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.
Is sound produced by changes in force's pressure's and velocity?
Sound and noise are sound pressure variations measured by an SPL meter. SPL = Sound Pressure Level.
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.
What instrument measures noise level?

What distance is loudness of sound measured?
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
What is the unit for the for the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
What determines the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
