Theoretically it should all work even with minimal volume, but at least for me the practice showed that it doesn’t work optimally with any device and it also depends on the individual’s sensitivity to morphic fields; I have done just a few years of chakras work/meditation before starting with fields and those things helped me attune a little bit better (at least) to Energy healing, energy work, and later morphic fields.
I have Two phones, both cheap.
I’ve dropped them so many times to the point where fields do not work for me, from those phones (not well enough anyway).
How do I know if they do or dont work?
Allergy, anti pathogen(s) fields, breathing fields, some fields for leg working (I feel my leg pulsating etc.) and others, as they either give me instant or immediate relief or better breathing or make me feel them, their effects etc.
Those are my go to, for testing.
Both phones work a little bit, but they are so inneficient that I can not even compare them to how they used to work before.
I’ve tried multiple other devices, like speakers, headphones, etc.
Currently using some pebble(s) speakers, they work FINE and FAST!! At least 10x better than one phone from which I still feel some effects, while the cheapest one is gone, barely or literally no effects from fields…
IF the device works for me, then low volume works too, although I usually let it be either louder or at least above the lowest audio volume (settings)…
Edit: speaker cleaner, you can use such apps or a website.
They can help, IF the phones not gone/broken/useless, with water or other particles, clearing/cleaning the phone’s speaker, etc.
Just a sec:
Edit 2: you also do not need to feel the fields working, they can give effects just fine, regardless if you perceive them on a subtle or other level or not (if they work for you, if the device is ok, etc.).
