3D Acoustic Modelling
Acoustic modelling is a computer simulation process where
dimensional data, taken from real or proposed rooms, is used to create a 3D model in drawing software such as Sketchup or Autocad and then imported into specialised acoustic modelling applications like EASE, Catt Acoustic or Odeon.

Within the modelling software, acoustic data relating to the types of internal finish materials are applied to the model faces to provide predictions of reverberation time. Expected or measured ambient noise levels and actual reverb time obtained from a site visit can also be added to help create an accurate impression of an existing room. Where a room is at the design stage, construction materials and acoustic absorption coefficients can be entered into the model to create an accurate prediction of how the room or space will perform acoustically. This means it is possible to make adjustments to a room to help with audio or acoustic issues before it has left the drawing board.


At Soundscape, EASE 4.3 (and the additional AURA module) is used for audio system design and electro-acoustic modelling because it has the largest library of manufacturer sourced speaker data. This allows a more accurate representation of the proposed sound system, rather than having to use a generic version of a speaker system which can be the case in other software. Other packages do offer advantages to pure room acoustics prediction and modelling but that is a specialism best left to acoustic consultants. In an ideal world, a room would be designed and modelled by architects and acousticians and then presented to Soundscape for further electro-acoustic modelling and system design within EASE.


Once completed, the model can be used to predict the room reverberation time, sound coverage, sound pressure levels, speech intelligibility and other useful data that all helps towards providing a cost saving, risk-managed, audio system design solution that meets stakeholder performance expectations within a given budget.
