Abstract:The basic theory of Micro-perforated panel absorber is introduced in this paper. Effect of sound absorption characteristics of parameters on the Micro-perforated panel absorber is analyzed deeply through the MATLAB simulation. And a simulation design system of micro-perforated panel absorber is developed based on MATLAB and LABVIEW code, which can design the micro-perforated panel absorber structure according to the requirements of the specific e
