As these pictures attest – we put quite a bit of detail into the room models we build.
That detail extended to careful inclusion of scattering data according to the shape and size of each surface using the in-built scattering wizard. Absorption coefficients were selected from the Ease database and the authors collected information.
A test loudspeaker and listener seat were installed in the model at the same locations as a balloon burst and test microphone were placed in the real space.
The Impulse response was generated in the model using the Aura routine and exported as a plain wav file. There are a number of formats available including Binaural Impulse Response – here we show the *.wav file opened in a free editor package.
We can then pull that simulated ballon burst into the Easera measurement package.
