[QUOTE="Ethan Winer, post: 343194, member: 14479"] Yes, exactly, decay time is meaningful only when a dB range is included. I usually aim for peaks at low frequencies to fall "through the floor" within 200-400 milliseconds, when the "floor" is 30 to 40 dB below the peak height. The graphs below show a typical room before and after adding a number of bass traps, so you can see a useful range for scaling. --Ethan [IMG]http://www.realtraps.com/dlr_before.gif[/IMG] [IMG]http://www.realtraps.com/dlr_after.gif[/IMG] [/QUOTE]
