Simulation Study on Sound Propagation in Short Cabin Pipelines
With the localization of aviation aircraft,the problem of aircraft engine noise has gradually attracted people's attention.Short cabin noise not only affects passengers' flying experience,but also poses safety hazards to normal flight.Therefore,it is urgent to solve the problem of short cabin noise reduction.Firstly,the basic work and current status of noise reduction research on short cabins at home and abroad were summarized,and the theoretical basis for sound propagation in short cabin pipelines was introduced.Secondly,combining the calculation and experiment of sound propagation inside pipelines,examples of simulation using software at home and abroad were listed.Finally,prospects for future research directions in this field were proposed in order to provide empirical guidance for related research.
