Modern architecture and design is increasingly using more materials for an industrial feel such as steel, concrete and glass to meet the demands current design trends of open space facilities. These hard surfaces reflect sound and contribute to an increase in noise levels and a decrease in productive environments. Au.diMicro micro perforated timber acoustic panels counteract the noise and the unpleasant effects on staff, students and visitors.
Au.diMicro consists of tiny micro perforations that are 0.5mm diameter to absorb noise and reduce the sound reverberation in the space, achieving an NRC value as high as 0.85, as tested by CSIRO.
Au.diMicro provides unmatched acoustic absorption while preserving the aesthetics of the timber face. The tiny perforations become invisible from a few steps away. The sound penetrates the panel through the multitude of micro perforations on the surface which acts as an Air Flow Resistance Layer to degrade reverberation. This is assisted by friction and heat loss via the tiny perforations as sound waves endeavour to penetrate the surface.
Sound is further channelled into the larger perforations located in the core of the panel where the second layer of air flow resistance – Atkar’s Sonus 2.0 integrated Acoustic Backing (SAB) – further enhances the sound absorption properties of the panel.
How does sound absorption work?
The aim of a sound absorber is to convert acoustic energy into heat energy. When the air molecules penetrate the micro perforated face, the friction between the oscillating air and the surface of the panel dissolves the acoustic energy.
Why do Architects love micro perforated panels?
The main reason micro perforated panels have become so popular among architects and designers is that they have excellent sound absorption performance but without the drawbacks of a porous material. Au.diMicro provides a surface that looks like a solid material, so can be suitable for use in certain environments as the perforations are too small for particles to enter. The solid timber aesthetics, available in a range of colours, adds to the popularity of Au.diMicro.
“Wooden micro-perforated panels (WMPP) possess excellent sound
absorption characteristics. For the demands of different projects,
selecting different structure parameters of WMPP, the
best optimization of the structure can be obtained. Because of
this WMPP structure has a good decorative effect; it is expected
to play a greater role in the architectural and the
acoustical design.”SHENG Shengwo & MO Fangshuo, Institute of Acoustics
