RE: What sized grid stopper should he try?

This brings up an interesting parallel to the HFAC filament discussions. Elsewhere it has been insisted that we cannot hear the effects of HFAC since the frequency is well above what humans can here. If this logic is to hold true then surely we cannot hear an oscillation in the mHz range yet people claim the effects of an oscillating tube as a bright or harsh sound.
what gives?
