Slat wall / slat resonator : calculating Q+corner wall depth

[pask74]

Hi there,

After Stuart has pointed me to those (very useful) links :

... I understand the Heimholz principle behind those designs and would like to know
- if the Q is calculable (not present in the Excel sheet)
- what depth from the wall should be entered in the table in the case of a corner slat wall.

Thanks!
