Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0022] The embodiment of the present invention is mainly to fabricate randomly distributed anechoic holes whose size continuously changes within a certain range on the acoustic lining substrate, so that the acoustic lining can act on noise sources with continuous frequency distribution and a wide frequency range, and achieve continuous frequency control. Noise reduction for distributed noise sources over a wide frequency range.
[0023] Fig. 4 is the schematic diagram of the structure of the broadband noise-reducing lining of the embodiment of the present invention, there are noise-eliminating holes 402 of different sizes on the sound-lining substrate 401; the noise-eliminating holes 402 are circular through holes with different diameters; The diameter ...
