Ensuring an acoustically comfortable environment within a school canteen is essential to promote the well-being of students and staff. In large spaces, where background noise and reverberation can compromise the quality of the acoustics, a specific and targeted intervention is indispensable.
The canteen in the case study has a total volume of 683 m³ and presented an average reverberation time (RT) of 2.66 seconds, a high value that contributed to creating a noisy environment.
To enhance the acoustics, 31 Silente sound-absorbing panels, each measuring 120x120x5 cm, were installed, suitable for application on both walls and ceilings. The panels are available both in a wall panel version, mounted using an installation kit with track and custom-cut bars, and in a ceiling-hung version with adjustable cables, allowing for flexible configurations by experimenting with different alignments and heights. This versatility enables the panels to be integrated in a flexible and functional way, addressing the specific needs of school settings.
The following graph shows an improvement in acoustic comfort: the average reverberation time decreases from 2.66 seconds to 1.18 seconds and the sound level is reduced by 3.51 dB.
These results demonstrate how the use of Silente panels with ceiling, wall or combined application can make the school canteen environment more comfortable and functional.
