And in a band context as Martin mentioned... Maybe also percieve very low "off notes" by instead noticing some sort of secondary standing waves that feels all wrong or are themselves off note "for the context" or interacts all wrong with both any playing notes and all of the instruments bodies present in the same room?
I've had a few shakers/tactile tranducers (or Exciters/Resonators as Monacor describes them) installed in both home cinema and hifi setup. They can really trick the mind in all sorts of ways...
I'm of the persuasion that we perceive acoustics, musically, with every cell of our body. I think of not only the cymatic effect of particular geometric resonances on our solid structures having an interplay of effects on the processes of our molecular makeup- but an intermodulation (freq mod, amp mod, phase mod) effect on our biorhythms, brainwaves, and other vibratory happenings within our body's system. This is why I was in a debate earlier this year on the discord over the use of oversampling filters in my music, and their shaping on the response of frequencies over nyquist (which for me currently is 22.5 khz). It wasn't that I was trying to be overly superstitious about hypersonic frequencies, but just putting thought to the fact that there are a gazillion processes taking place beyond what we consider our musical perception. Their "relevancy" is to be debated I suppose.
I kind of break down the hierarchy of perception/"happenings" like:
Conscious Identifiable Perception Of Bodily Effect >
Conscious Unidentifiable Perception Of Bodily Effect >
Subconcious Perception Of Bodily Effect >
Superconscious / Environmental Perception Of ExtraBodily Effect.
Our perception is like a Sunburst Gradient- where do we put our relevant edges?
