What is the noise pollution level in India?
Noise pollution levels differ from city to city & town to town
What is transistor noise?
http://www.vias.org/transistor_basics/transistor_basics_04_05_03.html The minimum signal that can be applied to a transistor is limited by the internal noise generated by the transistor. Since the transistor does not require cathode heating (one of the major noise sources in the vacuum tubes), it is inherently capable of operating at lower noise levels than its vacuum tube brother. At present, the junction transistor is equal to the vacuum tube, insofar as its noise characteristics are concerned. The noise level of the point-contact types is between 15 and 30 db higher. see the website, there is a lot more. do more research for certainty.
How does white noise work?
Life is full of disruptive sounds and noises, such as honking car horns, barking dogs, noisy neighbors, annoying snoring and screaming sirens. Unlike playing music in such instances, white noise does not add to the clamor of noise. Instead, white noise contains equal frequencies of all sounds. Research has shown that a steady, monotonous stream of the same peaceful sound, such as white noise, can filter and mask distracting noises. The same soothing sonic benefits of white noise are quite effective in creating the right ambience for both parent and child to enable a safe yet natural sleep. Among their recommendations for alleviating tinnitus symptoms, many audiologists and the American Academy of Otolaryngology - Head and Neck Surgery suggest masking the ringing sound: play a competing sound at a constant low level, such white noise, to mask the tinnitus and make it less noticeable. The Hyperacusis Network notes that "White noise contains all frequencies, and therefore very gently stimulates all the nerve cells in the these subconscious networks, allowing them to be more easily programmed, or reset, so that tinnitus signals are no longer detected. It also reduces the contrast between tinnitus and otherwise total silence." Fromhttp://www.PureWhiteNoise.com
What are the similarities between noise and music?
They both make a sound. Music is set up and sounds put together and it flows. Noise is annoiseing. Was that a good joke?

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.
What is the level of noise that affect hearing?
85 decibels.
What is a noise level of 65 decibels measured for?
Normal speech
At what noise level and your ability to hear be affected?
85 decibels.
At what noise level is your hearing negatively affected?
85 decibels
What is the measurement unit for noise level when rating coolers if you were in an office building and needed a very quiet system what would be an acceptable noise level?
Decibels.
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.
What noise is measured in?
Decibels
What is the unit of noise and music?
The unit for noise is decibels
How many decibels make up noise?
It depends on what organism is hearing the noise. For us humans, that would be 0 decibels.
What is the equivalent db level when listening to earphone or headphone volume?
dB is short for Decibel, or one tenth of a bel. Bels and decibels are unlike any other measurement, because an addition of ten means double the loudness of the noise. For example: 60 decibels is the noise generated from a regular conversation, however, 70 decibels is double the noise; and 80 is double that.
Define noise figure?
A noise figure is a scale of decibels.
