I've tried everything I can think of to stop or mute the 'ta-da' sound when checking sleep score and it's 'excellent'. It's disturbing and annoying when checking in public or quiet surroundings. Surely there's some setting somewhere to mute or deselect this annoying sound?
I dont believe you can pick and choose which apps have audio or not. I could stand corrected! But if it is so bad- turn down volume when opening the app, turn back up when finished
* there may be an option in settings- need to have a gander
