Controlling the Sound Environment Controlling Reverberation

In the real world, sound bounces off walls, floors, etc

If the bounce surface is hard, we hear a perfect echo

If it is soft, some frequencies are absorbed

The set of all echos is Reverberation

Java 3D provides a simplified model of reverberation

Sounds echo after a reverb delay time

Echo attenuation is controlled by a reflection coefficient

Echos stop after a reverb order (count)
