Decibel from A to Z. This is a brief list of things you should keep in mind about decibel: There is more than one kind of decibel. In fact, there’s a bunch. The dB has no embedded unit. Meaning that this unit alone doesn’t represent anything.

Continued exposure to noise above 85 dBA (adjusted decibels) over time will for Occupational Safety and Health, the maximum exposure time at 85 dBA is 

For those of you who know me, you probably know how big of a Rolling Stones fan I am (Drove to Columbus, Ohio a couple weeks ago and was reaaallly close to driving to Pittsburgh this morning too)! The maximal possible volume level we can obtain from sliding the volume control to more than 100% is approx. 153% above the normal peak limit. Provided we had set the ALSA volume with alsamixer to 100 these 100% are the level above which audio will be clipped or distorted.

SAFE & UNSAFE DECIBELS. The National Institute of Occupational Safety (NIOSH) states that for a 115 decibel (dB) sound, the exposure limit is just 28 seconds. Exposure to noise louder than the Environmental Protection Agency (EPA) safe noise level of 70 dB over 24 hours will damage hearing.

When the space shuttle took off the crackling sound was not the mics or recordings clipping, it was the air clipping. The air becomes less and less linear in its transmission of sound with increasing levels. There is the limit of the sound level of around 140 decibels. Some persons survive a louder level and some survive a smaller level. 2.
