What i mean is
for ex:
im sitting on a sofa with 2 of my friends beside me, minding their own business like using their own phones,
for normal fields i know that when i play an audio , as long as my two friends hear the music they will be affected.
now
what if i play a “smart” field and they both hear the music, will they be affected too or the field will only affect me ( the one who plays the audio) ?
Still, thank you for your reply, I learned something 
I see now, my bad. Well, I’ve just realized that I haven’t listened any smart field with anyone around yet (I’ll check again though).
One thing is that those are mostly the ones having a protection. So here’s what applies to them:
(This was said about a smart NFT. For some other smart fields, it might not even be the case, meaning that people in the same room wouldn’t even feel any bit of it nor affected by it).
Also, for some of the smart fields that don’t have any owner-exclusive protection, the fact mentioned below can happen too:

Are all smart fields interactive?
I understand for interactive fields as they can understand what an user tells them.
Shamanic medicine blend is explicitely mentioned as an interactive smart field in the description.
Not in others I’m aware (my mental and emotional supporter can work while you talk actively to it)
I suppose they could be considered to be interactive. It seems that many of our forum friends interact with their fields, smart or otherwise.
But I thought one component about what made a field a “smart field” was that it could review you, your energy systems and your situations and then decide (from its growing knowledgebase) what you needed worked on and in what order, so that you didn’t need to tell the field anything.
