In a multi-purpose centre designed to host cultural and social activities, including performances, conferences or exhibitions, the quality of the acoustics is very important. Acoustic upgrades in a recreational setting are necessary, for example, when public spaces have been renovated and converted for new uses, and may involve the installation of sound-absorbing panels that improve the acoustic comfort of users.
This case study presents acoustic correction measures applied to a multifunctional municipal hall around 380 m3in size.
As shown in the graph below, the sound level was reduced by installing 13 Silente 240x120x5 cm sound-absorbing panels suspended 30 cm from the ceiling, and 5 wall-mounted Silente panels, 3 of which are 240x120x5 cm in size and 2 of which are 120x120x5 cm in size. Completing the design are 4 free-standing D-Space partition panels measuring 120x160x5 cm.
| Average reverberation time without panels | Average reverberation time with panels |
| 2,93 s | 0,74 s |
The aims of the work were achieved, resulting in the reverberation time reducing from 2.93 s at an average of 250-2000 Hz to 0.74 s, and the sound level decreasing by 5.98 dB.
The acoustics in a multifunctional hall can be extremely complex, depending on the size and various ways in which the space can be configured, but with the right design, optimum sound quality can be achieved. Caruso Acoustic offers a wide range of sound-absorbing solutions that are highly customisable and respond effectively to various design requirements.
