I also hate the squawk, it ruins a good meditation, if your meditation fails it feels bad without having the need of that noise, so please can it be removed.
I don't like the buzzer sound, either. It's not happening every time, and there doesn't seem to be a pattern to when it buzzes and when it doesn't, so it seems like a bug.
I think it's okay if your meditation is short (though I don't know why it's short when nothing else around is happening), but not when you're getting say >200 energy from focussed meditation.
