Classrooms, particularly in kindergartens and primary schools, pose significant acoustic challenges. Inadequate control of reverberation and background noise can hinder concentration and learning, leading to stress and fatigue for both students and teachers.
This case study examines a primary school classroom with a volume of 123 m³. The simulation involved the installation of Silente sound-absorbing panels, specifically the following types:
- 8 Silente panels measuring 120×120×5 cm, mounted on the ceiling;
- 2 Silente panels measuring 240x120x5 cm, mounted on the ceiling;
- 2 Silente panels measuring 120x60x5 cm, mounted to the wall;
- 1 Silente panel measuring 240x60x5 cm, mounted to the wall.
Before the intervention, the classroom had an average reverberation time (Rt) of 1.59 seconds—above the recommended threshold for educational environments. Following the installation of the sound-absorbing panels, the average Rt decreased to 0.57 seconds, accompanied by a 4.42 dB reduction in sound levels.
Effective acoustic design significantly enhances sound quality, supporting improved learning and communication. Furthermore, the ability to customize the panels with colours and printed designs not only improves the aesthetic appeal of the space but also helps create an environment that fosters children’s development and well-being.
