The noise of machinery or equipment is a technical characteristic generally declared in terms of acoustic power (power level in dB in relation to a reference acoustic power of 10-12 watt). In Europe, this declaration of power is often imposed by regulation.

Objectives

Develop a primary reference source to disseminate the acoustic power unit
