This article reports that Qinetiq Ltd., the technology developer, spun out of the Defense Evaluation and Research Agency, is to provide predictive acoustic modeling for the United States plane maker Boeing Co. for its 7E7 Dreamliner. The aim of the work is a quieter cabin environment, achieved at acceptable weight and cost. Qinetiq claims it has unique capabilities in this area due to its many years of research into attenuation of sound and vibration through complex structures such as aircraft. Qinetiq's extensive experimental facilities include anechoic chambers, reverberant rooms and a transmission suite.
