I am a pilot and occasionally fly in airplanes louder than others. At all times, I wear a Bluetooth-enabled headset with active noise cancellation. I already have an automation set up to start a “Flying” focus mode that limits most apps and people from notifying me. Because the trigger is connecting to Bluetooth, I sometimes forget to actually activate it. Having said that, I’m looking for a way to limit notifications from the Noise app on my Apple Watch in that specific circumstance. I know airplanes are loud but I wear the best hearing protection available.
Maybe this solves it for you
