This conclusion is not that obvious to me for I used to think that EMF
in a coil depends on its speed and pressure is related to force, i.e.
acceleration. With the constant acceleration amplitude you are getting
lower speed amplitude at higher frequencies. The shorter period, the
lower max speed for the given acceleration.

I'll try, but we should keep in mind that preamplifier is to be with
no frequency correction.
