Our company uses professional acoustical software to predict the acoustical conditions inside room be it a concert hall, church, recording studio or home cinema.
Our software of preference is CATT/TUCT, which has been widely referred and ranked as one of the best prediction tools used is room acoustics.
Acoustical modelling means we need to draw a 3D model of the space being studied and
define the characteristics of every surface of the room as well as the sound source being used and location of possible receivers.
Such tools are important and much more accurate than typical numerical prediction such as Sabine or Eyring formulas because:
1 – It is possible to take in account the charateristics of the sound source
2 – It is possible to place the sound source and the receiver on any location inside the room
3 – Diffusion if used in room is defined in CATT which it is impossible to do with standard prediction methods.
One of the most known acoustical parameters to be studied in room acoustics is the Reverberation Time, defined as the required time for sound to be decreased by 60 dB. There are however other important acoustical parameters such as Clarity and Definition Index, Speech Intelligibility, Lateral Energy which can only be predict using computational modelling tools.
Acoustical modelling is a “hard” tool to learn with countless parameters. We have years of expertise using CATT/TUCT
For small room acoustics and particularly for control rooms we may also use a particular software that can predict the room modes of non-rectangular rooms if required.
This software ABEC allows to evaluate the sound pressure levels due to room modes at low frequencies as it can be observed below
