Slat Absorber Formula

Hi, Doeas any one know if there is a simple formula to work out the size of slats and how many slats you need based on the size of the room? I dont have excel so i am unable to download the info already on the site i have attached my sketchup file Thanks very much

Found it :D

So, are your slats and slots variable or all the same size? How did you determine each slat size and each slot size? The calcs I see determine 1 slat, slot size per calculation - which seems like what you are suppose to do if your airspace is varying behind and/or you are going for a broadband type slat absorber vs. a targeted hi q narrowband device... can you shed any light on what you are doing... maybe we can get some pointers from what you are doing... thx - David
