Ballesta® Hushtal Ultra-Microporous High-Efficiency Acoustic Ceiling System
Product Description
Academician Ma Dayou's paper "Theory and Design of Microperforated Panel Sound-Absorbing Structures", published in *Science China* in 1975, marked an important chapter in the history of China's acoustic technology innovation and initiated the widespread application of microperforated sound absorbers. In 1992, an article titled *A Chinese Engineer Drilled Thousands of Holes in the German Parliament Building* in Germany's *Bild* newspaper started a milestone where China's scientific achievements gained widespread international recognition and became a new research hotspot in fiber-free sound-absorbing materials. For this, Mr. Ma was awarded the ALFA Prize for fiber-free sound-absorbing materials by the Fraunhofer Institute for Building Physics in Germany in 1997.
When the diameter of the perforations in common perforated panels is controlled to less than 1mm, a microperforated panel is formed. At this point, the microperforated panel itself "has sufficient acoustic resistance and, at the same time, sufficiently low mass reactance, forming a broadband sound absorber without the need to add any porous materials". With the development and improvement of materials and perforation processing technologies, as well as its sound absorption characteristics of being broadband, efficient, clean and environmentally friendly, microperforated panel sound absorption structures are widely used in wall and ceiling decorations in numerous places.
Where can Ballesta® Hushtal Ultra-Microporous High-Efficiency Acoustic Ceiling System be applied?
1. Places with high requirements for both sound absorption and aesthetics, such as high-end office buildings, libraries, art galleries, exhibition halls, lecture halls, as well as theaters, concert halls, gymnasiums, bank business halls, hospitals, and ceiling places;
2. Spaces with a large flow of people, such as ceiling places in airport waiting halls, subway stations, railway station halls, and internal spaces of ships;
3. Spaces with cleanliness requirements, such as ceiling places in precision electronics workshops, pharmaceutical and biochemical product workshops, cigarette factory rolling and packaging workshops, food processing workshops, etc.
