A Study on the Sound Absorbing Performance of Parallel Perforated Plate Systems

  • 발행 : 2002.11.01

초록

An equivalent electroacoustic circuit approach of estimating the sound absorption coefficient for parallel perforated plate system is proposed. The proposed approach is validated by comparing the calculated absorption coefficients of a parallel single layer perforated plate system with the values measured by the two-microphone impedance tube method for various porosity and cavity depth.
