A method for determining the equivalent level of noise generated by a system of sources in an enclosure

This paper proposes and subsequently verifies a method for determining the equivalent noise level Leg of noise in an enclosure. This method requires the identification of "elementary signals" related to single "acoustic events" and measurements permitting the calculation of numerical values of some parameters (xi for each of these signals. This methods permits the determination of the values of Leg for any time interval when the value of ai and the number of "elementary signals" reaching the observation point are known.
