In this work, we report the exotic acoustic transmission behavior through hard plates perforated with a quasiperiodic array of subwavelength apertures. The phenomenon is verified to be originated from the coherent diffraction induced by the long-range order of the system. The experimental results agree well with the numerical ones. We also present comparative studies on the periodical and random systems to reveal the intrinsic physics in a universal way.
