基于正则化声压匹配法的舱室声场复现
Cabin Sound Field Reproduction Based on Pressure Matching Method Combining Regularization Technique
摘要
Abstract
Aircraft noise control,sound quality design and other researches require lots of acoustic field experiments carried out in the cabin.However,the real aircraft flights are too expensive to be frequently performed in the study.Reproducing the sound field in an experimental cabin is very important and valuable to reduce research costs and carry out repeatable experiments.In this paper,a multi-target point sound field reproduction algorithm based on the classical sound pressure matching method is established.to improve the accuracy in the real environment where there is obvious noise,and the regularization technique is introduced into the method.The reproduction system is built in an experimental aircraft cabin environment.The reproduction experiments show that the algorithm can reproduce the target frequency response curve at multiple points in the specified cabin with a relative error of less than 5%in a wide frequency range.The method has good prospects in the aircraft cabin acoustic environment reproduction applications.关键词
