Sound Scattering by a Flexible Plate Embedded on Free Surface

Table 2

The effect of the central hole’s radius on the pressure amplitude as averaged over the plate’s surface. The pressure is expressed as relative to the incoming pressure amplitude of 1 (Pa), and the rest of the conditions are as in Figure 5.

Central hole’s radius (m)	0	0.2	0.4	0.6	0.8
Hinged plate, pressure	1.6907	1.6922	1.5616	1.7017	0.3038
Clamped plate, pressure	1.6845	1.6218	1.6810	1.5069	2.599
