To my understanding AURA requires the room to be closed prior to calculating the room response. I have tried to put the structure inside a pseudo-room with 1.0 alpha "ABSORBER" material, however besides one strong specular reflection (from the ground plane), I am getting some diffuse behaviour at about -50dB level. What is the correct way/workaround to dealing with an outdoor model? Are there any perfectly absorbing materials that can be used? Best regards, Jon. _________________ --Jonathan Posted: Wed Sep 01, 2010 11:30 pm Lindsay Smith Member   Joined: 16 Apr 2009 Posts: 19 Location: Seattle, WA Not sure what you mean by diffuse behavior but have you set all the noise levels in Room Data and in Eyes to 0?
