Adjusted radiation efficiency of a rectilinear glazing surface, computed using the zeroth-order σ(0)(kp) (blue) and first-order σ(1)(kp) (red) adjusted radiation efficiency, along with the numerically integrated reference curve σ(kp) (black). The gray dashed lines represent the typical frequency range in building acoustics, spanning from 50 Hz to 5 kHz.
