Perforated Flexible Membrane Insertion Influence on The Sound Absorption Performance of Cavity Backed Micro Perforated Panel
Harjana Harjana, Iwan Yahya
Sound absorption performance of cavity backed perforated panel on respect to the influence of flexible perforated membrane insertion was investigated by using a laboratory experiment. A layer of perforated flexible membrane was fitted inside the cavity backed MPP and the sound absorption coefficient...

Cavity Sound Pressure Enhancement of the Second Generation Power Generating Helmholtz Resonator with X-shaped Cavity Junction
Iwan Yahya, Harjana Harjana, Eqi Muqowi
Cavity sound pressure level is a very important measure when dealing with the design of resonator based power generating sound absorbers and sound diffusers. This paper presents results from experimental study of the performance of the second generation iARG-X2 power generating Helmholtz resonator. The...
