A micro-perforated panel itself has a rather low sound absorption. However, the sound absorption drastically increases at the resonance frequencies if an air layer exist between the micro-perforated panel and the rigid backing material. Two analytical models,the shunt lumped and the distributed models analogous to an equivalent electric circuit, are available to account for the sound absorption characteristics.

The micro perforation is applied to real wood veneers and is only visible from nearby. Leeyin micro perforated mdf board gives a good sound absorption over a wide range of frequencies. Apart from being almost invisible, the micro perforated mdf board from Guangzhou Liyin Building Material Co., Ltd. provides a perforation pattern all the way out to the edges (no frame). Due to this, the installation will appear more homogeneous.

Installation:

with our light steel keel or wooden keel or nail gun.

Application:

The wooden acoustic panel is suitable to use in any project that needs acoustical solutions, such as concert hall, theater, school, airport ects.
