Research on detection architecture and measurement method of stage machinery noise

With the prosperity of culture market and the construction of performing places such as theatre and opera house, stage machinery is indispensable to show the expression of stage better, measurement and evaluation of the noise generated by stage machinery has also been the object concerned by more and more people. After a large number of analysis and extensive research, in this paper, we present that the detection architecture of stage machinery noise should be composed of background noise, noise in auditorium and machine-side noise, and detail the measurement method of each part, which provides a theory and measurement basis of machine-side noise and auditorium noise evaluation and control, lay a foundation further of stage machinery measurement and control standards.
