What should be your ultimate target level? The answer is, to a large degree, tied to the system that will be used to deliver the music to the consumer. If you’re mastering strictly for CD, start by setting your final limiter’s output ceiling to -0.2 or -0.1 dBFS (never to 0.0, or intersample peaks can sneak through and cause distortion on consumer playback devices).

The following decibel levels of common noise sources are typical, but will vary. Noise levels above 140dBA can cause damage to hearing after just one exposure.

The average person can hear sounds down to about 0 dB, the level of rustling leaves. Some people with very good hearing can hear sounds down to -15 dB. If a

A power level of 0 dBm corresponds to one milliwatt, and 1 dBm is one decibel greater (about 1.259 mW).

That is, the threshold of hearing is 0 decibels. Maximum Permitted Noise Level.

Max decibel level




The bel, upon which the decibel is based, is named for Alexander Graham Bell, the inventor of the telephone. The decibel level of a sound having the threshold intensity of 10 −12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of hearing is 0 decibels.

In Europe, most television networks set this maximum peak level at -9 dBFS.

(a) Protection against the effects of noise exposure shall be provided when the sound levels exceed those shown in Table N-1 of this section when measured on  

The table below can be used as a guide to maximum acceptable sound pressure levels in rooms with different types of activities. 2018-03-13 Each line by itself represents 100% of the allowable noise dose per 24-hour day. In other words, if you've already experienced 15 minutes at 100 dBA, you're "done for the day," and the remainder of your 24-hour period should have NO exposure above 85 dBA, and preferably should be below 70 dBA. Different levels are used for other platforms such as cinemas, DVDs, radio, video games etc. The Maximum Peak Level refers to the absolute highest level of a signal. In Europe, most television networks set this maximum peak level at -9 dBFS.

It has a clever in-built mechanism that reduces its own sensitivity as the sound level rises and it also has the remarkable ability to handle an enormous range of sound power levels. Auto Decibel Database 2018-06-07 · Decibel levels are important to you because they tell you how loud or quiet a sound is and this is very important as if something is too loud it can damage your hearing permanently. We usually measure how loud sound is through the use of a measure called the decibel, one decibel being one tenth of a bel, a very infrequently used measure. The decibel level of a sound having the threshold intensity of 10 −12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of hearing is 0 decibels.
