By changing the position of the partitions in the grooves at the back of the BuzziResoFuser, it is possible to absorb frequencies efficiently. This can be done by placing three partitions at the same level or at differing heights. To determine which frequencies have to be absorbed in the room, a reverberation time measurement has to be taken. The frequencies that remain in the room for longer periods have to be absorbed. The frequencies can be read on the back of the BuzziResoFuser. These frequencies have a specific bandwidth, which means that a frequency can always be chosen that is
close to the problem frequency measured in the room.
