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.
What else can I help you with?
Make a sentence with the word noise?
Take that noise outside, Private! What was that noise? Noise is unwanted sound.
How do you spell a licking sound?

The meaning of the word silence?
1. The condition or quality of being or keeping still and silent.2. The absence of sound; stillness.3. A period of time without speech or noise.4. Refusal or failure to speak out.absence of any sound or noise; stillness
What is the sound level of the noise measured at 42 dB?
The sound level of the noise measured at 42 dB is considered moderate and is similar to the noise level of a quiet library.
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 loud is the noise level when the sound is measured at 55db?
At 55 decibels, the noise level is considered moderate and similar to a quiet conversation or background music.
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 a noise level of 65 decibels measured for?
A noise level of 65 decibels is equivalent to the sound of a normal conversation or background music in a restaurant. It is also the recommended noise level for a comfortable working environment.
What is the maximum allowable noise level in a residential area, measured in decibels, with 55 dB sound being the threshold for acceptable noise levels?
The maximum allowable noise level in a residential area is typically around 55 decibels. This is considered the threshold for acceptable noise levels in residential areas.
What is a noise level of 70 decibels measured for?
A noise level of 70 decibels is equivalent to the sound of a vacuum cleaner or a busy street. It can be considered moderately loud and may be disruptive to some activities requiring concentration or quiet environments.
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?
Sound level meters Loudness meters Noise dosimeter
What equipment is used to measured sound?
sound level meter
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.
