Acoustic comfort is essential for clear listening in conference spaces, especially at medium and long distances. This case study presents an acoustic upgrade performed in a rectangular conference room with a total volume of about 1073 m³.
In the design phase, the space’s specific functional requirements were assessed, which revealed an average reverberation time (RT) of 3.60 seconds in the unoccupied room, a value too high to ensure clear speech intelligibility.
The simulation using Caruso Acoustic products showed that installing 32 Silente sound-absorbing panels (16 elements of 240x120x5 cm suspended 30 cm from the ceiling and 16 elements of the same size mounted on the wall) resulted in an effective reduction in reverberation time from 3.60 s to 1.20 s. This also led to a 4.76 dB reduction in overall sound level.
Proper arrangement of the sound-absorbing material was key to achieving this result: a combination of ceiling-hung and wall-mounted panels ensured even sound distribution, improving sound clarity throughout the room.
This intervention demonstrates how studying the environment and employing targeted design are crucial for optimal acoustic comfort in large conference rooms.
