Project: Open-plan call centre
Room size: 162 m³
Acoustic Problem: high reverberation times resulting in mental fatigue for employees
Environment liveability, quality of speech intelligibility and adequate levels of privacy are essential elements for the correct acoustic treatment of call centre offices.
The proposed acoustic correction project refers to a call centre environment with 16 workstations. The office area covers 60 square meters with a volume of 162 m³. The reverberation time calculated before the proposed work is 2.10 s at an average of 250-2000 Hz (frequencies involved in speaking), therefore inadequate for any type of work activity. Given the type of room and its size, achieving a reverberation time ranging between 0.40 s and 0.60 s has been set as a goal. Based on acoustic calculations carried out, we can achieve a reverberation time of 0.52 s at an average of 250-2000 Hz by installing 8 Silente suspended sound-absorbing panels and 20 Scriba desk panels.
| Average reverberation time without panels | Average reverberation time with panels |
| 2,10 s | 0,52 s |
The combination of these two products perfectly meets the specific project requirements. In fact, the Silente suspended panel permits to freely modulate the distance of the panels from the ceiling, thus effectively intercepting both the direct and the reflected sound. The two-sided Scriba desk panel, on the other hand, is designed to be easily installed on horizontal surfaces by means of a special clamping system or sustained by its base, therefore enabling the separation of each employee’s operating area, improving privacy.
The proposed acoustic treatment allowed to decrease the reverberation times inside the room, improving the general livability of the work space by diversifying and distributing the sound-absorbing material uniformly over the entire work area.
