Fig. 10.

Focal gains determined from both direct FOPH measurements and modeling (color online). The data shown in Fig. 6 are included along with steering simulations. Peak pressures at the focus are normalized to the corresponding nominal source pressure p₀ for no-steering case. Note that the adjusted p₀ was used in the boundary conditions for the steering case to account for the increased output level required to achieve the same linear focal pressure as measured without steering.
