Apple Watch's Noise App Automatically Monitors Decibel Levels

Apple’s Noise app on their Watch informs you when you should plug your ears to avoid hearing loss! It monitors the sound with a built-in dB meter and considers anything above 90 dB as harmful.

I think most people on the forum would agree this is a killer feature!

If I’m correct, it also monitors your headphone usage... see screenshot!

This Apple Noise App has a huge bug. It is deaf for frequencies above 8 kHz. You can try other dB measurement applications to measure this range, but with Apple Noise App, if I play a 80 dB sound at 9 kHz, it says 40 dB, no sound and no harm apparently.
