✦ Synopsis

The calculation of resonance and anti-resonance frequencies of a double layer microperforated sound absorption structure is studied, and simplified analytical formulae which will be very useful for the design and analysis of wide bandwidth double layer microperforated sound absorption structures are derived. The results obtained provide an effective method for the design of wide bandwidth microperforated panel silencers.
