Placement matters almost as much as quantity. A panel in the right spot removes a strong reflection; the same panel in a corner nobody hears may do very little. In libraries, start here:
- clouds over reading tables
- baffles over the circulation desk
- panels at the ends of stack aisles
Spread them out
Absorption works best spread across several surfaces rather than all on one wall. Treating two facing walls stops sound bouncing between them (flutter echo). If you only treat one of a pair of parallel walls, alternate panels on each so no strip of bare wall faces another.
Height
In libraries most of the sound energy reaches the ceiling, so hang ceiling products evenly over the occupied area, not just in one zone. Keep them clear of sprinklers, lights and air diffusers.
Wall or ceiling?
For libraries we suggest roughly 40% of the treatment on walls and 60% on the ceiling. In larger rooms the ceiling is the biggest surface you can treat, and the closest to every listener.
