'''Diavik Airport''' {{Airport codes|||CDK2}}, is a private aerodrome in the [[Northwest Territories]], [[Canada]] that serves the [[Diavik Diamond Mine]]. It's situated in a busy area due to the closeness of [[Ekati Airport]]. Prior permission is required to land except in the case of an emergency.

'''dB(SPL)''' is an abbreviation for [[decibel]]s [[sound pressure level]]. It is sound output expressed purely as a pressure (force/area). It is used primarily by [[car stereo competitions]] to see whose can generate the "loudest" (more pressure) sound in closed car interior. They are measuring sound pressure. A [[sound engineer]] for a [[rock concert]] measures dB(watt) = dB(w) = dB(swl) and may increase power so the sound is still loud very far away.

Say they both generate an enormous 1000 acoustic watts = 150 dB(w). In a [[car stereo]] this is a painful level of about 165 dB(p). This same 1000 acoustic watts in a large [[stadium]] it is "diluted" to a nice but loud level of 100 dB(p). So depending on the environment the various sound dB levels change "BY THEMSELVES".

==References==

Sound can be a pressure; dB(p) or a watt dB(w) or a velocity dB(v).

*{{CFS}}

Conveniently, they are very closely equal and interchangeable below 120 dB. Above 120 dB it should be expressed as a pressure dB(p) or a sound wattage dB(w). 95% of all sound meters measure pressure. Special Computer controlled sound meters or programs may give you a dB(watt) level they can be found at: http://www.makeitlouder.com/Computer%20Software.html
