Vinyl in the database is not found. Posted: Thu May 26, 2016 5:47 pm thomas Member   Joined: 16 Mar 2011 Posts: 73 Hi Anton, you have to define a new material. I suppose the roof is a membrane? Then take the mass/area, calculate (aproximate) the transmission coefficient (mass-frequency-law) and use that as the absorption coefficient. That is ok as long as no reflection comes back through the membrane from the outside (e.g. from walls outside the tent). kind regards Thomas AFMG Network Forum Index -> EASE 4 You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT   Page 1 of 1   All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum General----------------Board RulesForum Announcements Software Forums----------------EASE 5EASE 4EASE EvacAFMG EASERAAFMG SysTuneAFMG SoundFlowAFMG ReflexEASE FocusEASE AddressSDK for GLL PLug-in API   Powered by phpBB © 2001-2003 phpBB Group Theme created by Vjacheslav Trushkin Variation by CodeWeavers and AFMG
