about Tianyi decorative acoustic absorption panel
Tianyi decorative acoustic absorption panel is made of polyester fibres, being hot pressed, with the function of permeability and various density. A famous acoustic professor of Shanghai Tongji University has described this product like this, " The polyester fibred coustic absorption panels is an up to date interior decorative material which combines both acoustic absorption and thermal insulation.
Tianyi decorative acoustic absorption panel is of very good acoustic absorption characteristics. Table 1 shows the acoustic absorption rates, this test was done by The Acoustic Institute of Tongji University, by way of acoustic reverberation room testing, testing panel sized in 9mm thick, 2.25kg weight. The test data proved, that "the performance of polyester fibre acoustic absorption decorative panel is over A grade acoustic absorption material standard, when it is installed by 50MM cavity; When cavity reached at 200mm, from 100-5, 000Hz, the acoustic absorption rate showed high value. The result is, this kind of material can be used for full frequency acoustic absorption matrial. "
Characters of Tianyi decorative acoustic absorption panel
Besides, Tianyi decorative acoustic absorption panel is of the following advantages.
1. Tianyi decorative acoustic absorption panel has vaiouse color options, like red, green, blue, white, orange, purple, tan, black, etc. And is of flat or texturer surfaces, no longer needs additional surface decorative material.

Applications of Tianyi decorative acoustic absorption panel
Tianyi decorative acoustic absorption panel can be used for interio wall or ceiling decoration material, is applicable to show rooms, concert halls, movie theaters, meeting rooms, dancing halls, stadiums, conference rooms, classrooms, etc., better to control the reverberation time, to obtain qualified acoustics result. It is also good for the waiting hall at airports, train station, shopping centres, exhibition hall, hotel lobby, hotel restaurants, library, reading room, open-style office, and etc. Public venues, to reduce noisy reverberation, to provide more quiet environment. Of course, it can be also used for acoustic absorption at factories and generator rooms.
