During consultancy various acoustic models are used to predict the acoustical behavior of materials, rooms and buildings. More frequently new materials and constructions are proposed by architects and interior designers. In many cases, the acoustic performance of these materials is unknown and has to be predicted. Room acoustical parameters can be predicted using a geometric model using image source modeling and ray tracing.
Sound insulation of materials
We can estimate the sound insulation of various types of materials and constructions with the program BASlab.
Sound insulation between rooms
We can estimate the sound transmission from room to room using the program BASluco.
Sound absorption of materials
We can estimate the sound absorption of materials using the program
WINFLAG and
BASabs.
Room acoustical predictions of rooms
For the modelling of reverberation time in rooms with a more common geometry, the
software program
SABIN is used. In case more detailed analyses are necessary the program
CATT Acoustics, Acoustics is used, a program based on image source modeling and ray tracing in a geometric model of the room. 3D models in AutoCAD or Sketch up can be transferred to CATT Acoustics by the SU˛CATT plug-in.
office is used in CATT acoustics to
predict speech intelligibility.
is made with the use of the
program WINFLAG.
