Large room acoustics involve different spaces such as: concert halls, theaters, class rooms and churches.

Each one of this spaces can be quite complex and therefore require a computational model to study the acoustics inside the room.

We use CATT for room acoustics prediction and INSUL / SOUNDFLOW for sound transmission prediction of partitions. We also built property software of our own.

A computational model can predict the acoustics of large spaces dedicated to speech or music as shown below:

With this model it is possible to predict several parameters such as:

Reverberation Time extrapolated from T20 ,T30
Sound Pressure Level across the room
Clarity C50 and C80 and Definition D50
Lateral Fraction
Speech Intelligibility

These studies fall into two categories;

Existing spaces that want to know what type of treatment should be performed to improve indoor conditions
Future spaces that want to know what acoustic treatment should be implemented.

Modelling existing spaces

Ideally, client should measure the current room conditions
Execution of the 3D computational model with information of all surfaces of the room and their acoustic characteristics
The model predicts future parameters in different points of the room


Evaluate different acoustic treatment options
Combine the acoustic treatment part with the visual integration
Visualize the different acoustic parameters across space
Model determines the impact of future changes
