Level of safety. Decibels (Approximate). Noise ordinances are noise regulations which limit the allowable noise level(s) The maximum allowable noise levels are typically higher during daytime hours The standards permit the highest noise levels in industrial areas and are most stringent in residential areas.

For a pure tone, the Peak will be 3 dB above the Maximum Sound Level. For varying signals there can be a huge difference and there is no way to calculate the Peak from the Max or any other measurement. Unlike the Sound Level and the Leq, the Peak measurement is usually C-Weighted rather than A-Weighted. So -10 dBFS means a level that is 10 decibels lower than the maximum level your system can handle. Different video and audio services have different rules on what dBFS level should be adhered. For example, it is common for television channels to use -18 dBFS for their content (i.e. 18 decibels below the maximum 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.

But what is audible distortion? Traditionally, the threshold has been a total harmonic distortion (THD) of only 0.5%.

The decibel unit can also be combined with a reference level, often indicated via a suffix, to create an absolute unit of electric power. For example, it can be combined with "m" for "milliwatt" to produce the "dBm". A power level of 0 dBm corresponds to one milliwatt, and 1 dBm is one decibel greater (about 1.259 mW).

With its ingenious internal mechanisms and physiology, the human ear can adjust its sensitivity to increasing sound levels and handle a vast array of sound power levels.

There’s a lot of debate online about the right way to level audio, but there’s one thing that everyone can agree on: you should never go above 0db. Even though your NLE may allow you to raise your audio levels all the way up to 6db, it’s advised by virtually everyone that you should keep your audio below 0db. What Decibel Levels Mean Understanding safe vs. dangerous decibel levels can be easier when you know how decibel measurement works.
