IDENTIFICATION OF ACOUSTIC SOURCE STRENGTH WITHOUT PRIORLY KNOWING THE NUMBER AND LOCATIONS OF THE SOURCES

摘要

The identification of the strength of acoustic sources is a fundamental problem in noise control. This subject has been investigated extensively, and many different methods have been proposed in the past. However, most of the methods assumed that the number and locations of the sources were known. In this work, an identification procedure was dereloped without knowing the number and locations of the sources in advance. The simulated results demonstrate that the proposed procedure is very efficiency and the identification results are also accurate enough for practical engineering application.
