This is how much the reverberation time decreases in an open-plan kitchen-dining-living room
In a typical open-plan kitchen-dining-living room, where many family activities take place, a reverberation time of 0.6-0.8 seconds
is good. The example below shows the reverberation time in the same living space with and without a Troldtekt acoustic ceiling. The reverberation time
decreases on average from 3.22 seconds to 0.46-0.71 seconds after installing Troldtekt.
