Design of Multiple Parallel-Arranged Perforated Panel Absorbers for Low Frequency Sound Absorption
A particular structure that consists of four parallel-arranged perforated panel absorbers (PPAs) is proposed for the low frequency sound absorption within a constraint space. The apertures of the perforated panels are set to ≥1.5 mm, and the number of orifices is much less and therefore easier to be...
