Hey thanks for your tips j_tour. It might be a good idea to get a dB meter actually. I think I will just go ahead with it on the digital piano and hope for the best.
anacrusis yeah I will look into running a business from your home and any rules that come with that, as far as I'm aware there aren't any specific rules, but I'll have to check to be sure.
Hoping they appreciate piano playing and don't find it too annoying!
There should be hours where a reasonable amount of noise is fine. People can use power tools to maintain their homes during the day time.
I provided my perspective, but I am not a piano teacher, so I may not be understand your situation well enough.
From the perspective of a student, at my level, I wouldn't learn from a teacher with a digital piano because considerations of the touch and tone of the instrument become very important. Just pointing out that this is a consideration.
