My girlfriend is lung transplanted and some of her medicine she have to take through inhalation
She uses the eFlow Rapid from PARI (https://www.pari.com/de/produkte/lunge/eflow-rapid-inhalationssystem/) for that use case and according to the company, this device is quiet.
It works with am membrane that turns the liquid into steam using ultrasonic sounds.
There is just one downside to this device. When we're both sitting on the couch and she is using that device (she usually sits right of me), as soon she starts that thing, i can't hear it, but feel pressure in my ear. Its not really pressure, its very hard to describe, but i can "feel" it.
And sometimes she is using that for up to 15 Minutes and after she finished, when she turns it off, i feel instantly relieved and not just a bit. It feels like pain relieve in my ear drum. My brain adjusts to the sound when she is using it and as soon those ultrasonic frequencies are gone, everything sounds a bit off for a few seconds.
And this is not the only instance. A lot of her medicine equipment produces very high frequencies in the power supplies that is horribly annoying. She can't hear it anymore (one medicament she had to take right after the transplantation damaged her ear so she can barely hear anything beyond 10khz (but surprisingly normal below that) but i am constantly running through the house to check in which power plug she forgot to take out one of her devices.
But those are all just annoying sounds, nothing is close to the "pressure" and afterwards "relief" feel of the eFlow.
Its so annoying that i can no longer sit beside her when she is using her inhaler without using headphones or earplugs

), i am able to hear a somewhat grainy white noise. I had this with all headphones so its either my ear or this is how physics work (not a sound scientist, maybe someone can answer this)
