Don’t we all naturally seal our nostrils from smell when we use non-nasal sounds? Think a nasal ahhhh sound versus a non-nasal ahhhh sound.
Although I am guessing sealing nostrils from water versus from smell is distinct: I feel you can seal at the front “inside” the nostrils (think blocked nose) versus sealing at the back (soft palate?). Edit: Also when you blow your nose, i think you partially use the muscles that close off the nasal passages?
Although quite possibly I am misunderstanding something - we often struggle to even realise what we naturally do (e.g. when swimming) or struggle to understand that others do things differently.
I tried to exhale through my nasal passage and then block it off with just the muscles in my nostrils, building pressure in the nasal cavity. I cannot do that.
