OPTIMISATION STUDY FOR STRUCTURAL ACOUSTICAL CONTROL’CONFIGURATION ON THE FOKKER 100 USING RECIPROCAL TESTING

摘要

Interior noise redaction in aircraft is a topic on which a considerable research effort is spent. Active noise control is one of the main topics addressed to this purpose. In the previous years, an extensive evaluation was made of the possibilities of pure acoustical control configurations using loudspeakers. Commercial systems have been developed and are being used industrially. Recent research has been directed to apply structural secondary sources.This topic is for example addressed in the Brite Aeronautics project “ASANCA 2”.
