FIGURE 12-24 Typical resonant panel absorber with wall mounting.
A corner panel absorber is shown in Fig. 12-25. For computations, an average depth is used.
Depths greater and smaller than the average simply mean that the peak of absorbance is broader than
that of an absorber with uniform depth. Spacing the absorber 1/4 to 1/2 in from the rear of the
plywood panel is simple if a mineral fiber board such as Tectum is used. Using a flexible blanket of
