Technical Focus SOUND ABSORPTION
The surfaces of workplaces are usually made with hard and durable materials for easy cleaning and maintenance. This means that they reflect the sound. The sound absorption factor of the false ceiling is very important in achieving good acoustic comfort. The Proterceiling radiant panels can be perforated in design with open percentages and hole size on request. Furthermore, the panels can be equipped with high-performance acoustic veils and high-density acoustic insulation.
Compared to the systems with aluminum heat diffusers, the M Series copper heat exchanger occupies only a small part of the panel microperforation.
Case Study Classroom Fashion ResearchThe goal is to ensure a reverberation time of the room so that the word is intelligible, according to both the use of the premises and the current standards. While the reverberation time of the room to be treated can be estimate by mathematical calculations, for a more reliable prediction, we made on site measurement of the reverberation time ante operam. The measurements in classrooms (8,7x6x3,6h m) with no radiant ceiling were:
Reverberation time in octave frequency
Test values refer to a steel false ceiling with 1,8 mm hole size, 19% open area, suspended at 300 mm from the ceiling.
The results of the measurements carried out after the Vega Office radiant ceiling installation have highlighted how the reverberation time and the STI index ranged from just good to excellent:
