Abstract: Acoustic metasurface is a kind of ultra-thin planar structure composed of artificial micro-units,
which has important application prospects in acoustic field control, noise control, and many other acoustic
fields. In this paper, the noise spectrum and mode amplitude of a single-stage fan compressor at 2100 r/min
is taken as the input condition, and a broadband noise reduction liner is designed based on the acoustic
metasurface theory. The noise reduction characteristics of the metasurface noise reduction liner in the pipeline
are studied, and the noise reduction characteristics are verified on the single-stage fan compressor test platform.
The results show that the noise reduction lining structure has a good noise reduction effect under the design
condition (2100 r/min), basically consistent with the design value, and in the wide band (300–6000 Hz) noise
reduction effect is obvious, the total sound pressure level reduction more than 12.6 dB, has a good wide band
noise reduction ability. In addition, in the off-design condition, the noise reduction structure also has a good
noise reduction effect, which demonstrates its wideband noise reduction capability under multiple operating
conditions.
