15.17. Summary of electrostatic loudspeaker design

We can see from Eqs. (15.19) and (15.20) that to maximize the radiated sound pressure, the field strength E P /d should be as close to its maximum allowable value as possible, which is around 2   kV/mm. Similarly, we generally set the maximum peak signal voltage 1 2 e ˜ in image to the same value as the polarizing voltage E P because the maximum sound pressure is proportional to the product of the two, but their sum should not exceed 4   kV/mm.
If the gap distance d is reduced, we can reduce both E P and e ˜ in while keeping the sound pressure constant. Hence ...
