Ears are pressure transducers. This means that the ear drum almost
doesn't move when sound hits.



** That is a non sequitur.

Ignoring proximity effect, diaphragms of omnidirectional (ie pressure) mics move the same amount as those of cardioids when exposed to the same sound. The cardioid has to be pointed at the source to get max output.

If the mic is a dynamic, excursion is inversely proportional to frequency cos output depends only on voice coil velocity.

If it is a condenser type, excursion is independent of frequency cos output depends only on diaphragm displacement.




A blast of air from a pop has very
little pressure, but a lot of velocity.
