Tucker..
It sounds (no pun intended) like Tucker actually invented the first MAF or "mass air flow" sensor, used commonly in automotive applications to determine the amount of air being consumed by an engine, and adjust the fuel/air ratio accordingly, although his application of it was obviously different.
I wonder if you could replicate his efforts in filtering low-frequency sound by using a spare MAF from a vehicle, if so inclined..
