Scene Demand
As office buildings are places where people work, they must always provide a quiet environment; sound should be transmitted clearly, without echoes; at the same time, the sound insulation between different rooms must be sufficient to ensure that conversations cannot be overheard through the walls.The standard approach is to install perforated ceiling panels lined with sound-absorbing paper to create a peaceful and quiet public environment, whilst fitting sound-insulating felt to office partition walls to enhance sound insulation between rooms.Various sounds are generated in office areas through staff interactions, meeting discussions and the operation of air-conditioning systems. As the space is open and airy, sound tends to spread and cause interference, which not only reduces concentration whilst working but also affects the clarity of conference calls. Perforated suspended ceilings combined with acoustic nonwoven minimise indoor reflected noise; sound-absorbing foam pads absorb high-frequency, fine-grained noise; and sound-insulating felt blocks sound transmission interference between floors and adjacent cubicles, effectively controlling indoor noise levels to create a quiet and efficient acoustic office environment.
Typical Acoustic Design
The ceiling is constructed using perforated panels, with silence tech acoustic nonwoven backed onto the rear of the panels. The standard perforation rate is 10–30 per cent, which absorbs mid- to high-frequency sound waves and reduces echoes.
Silence Tech soundproofing felt and acoustic foam are used between office walls to enhance the walls’ sound insulation properties, further improving the quiet and comfortable working environment.
In the case of larger meeting rooms, in addition to sound insulation, it is also necessary to address the issue of reverberation. By incorporating wall structures with built-in Silence Tech acoustic materials, the reverberation time within the meeting room can be effectively reduced, thereby resolving the problem of echoes.
