Loud noise notification without loud noise

High recorded noise levels could be either a faulty microphone, or hallucination in the software. I suggest you test the watch's microphone by making a test call to someone who will report back whether there is noise when you are not speaking. If the call is clear you are probably dealing with a software glitch.

Remember that a low level sound very close to the mic may be detected as a loud noise. For example, if you tap with your fingernail or a pen top on the watch casing it will hardly reach your ear but the watch interprets it as much louder from greater distance. I would try to expand the timescale for the sound level bars if possible and look whether it is constant false noise, or simply a few short transient sounds which are distorting the picture.

Have you tried a forced restart of your Apple Watch? It’s more than just turning your Watch off and back on and resolves many issues like you’re describing.

Blowing out the mic on the side of the watch with canned air fixed the issue!

What has worked for me is cleaning the watch with hot water, the mic works fine after this, and no more loud noise notifications.

Not at all... it's the wind blowing across the microphone on the watch.. If/when possible, wear long sleeves to cover your watch on disable that function during workouts. Those are my "work-arounds" until Apple addresses the issue!

I’ve had the same issue and finally realised it’s triggered by the car air *** blowing on my watch while driving!

Oh gosh i have same thing today on my walk and no loud noise. The wind is there tho and it says loud qhen it blows hard but still by far this wind is not that hard and def cannot do hearing damage. Like its a summers day and the wind is slightly gusty. Im glad u mentioned wind because if i turn microphone and see how its reacting to wind its saying “too loud” over that mark when it blows. Im wearing a tshirt and cannot wearblong sleeve in this weather. Come on apple this is dumb.

Yes I’m in a quiet room nothing going but ceiling fan and it keeps telling me every 5 minutes it’s 130db?? It’s very frustrating and no way to reset or turn off. I’ve turned watch off and back on and immediately got loud noise warning.

Mine seems to be stuck between 100-108dBs. Even in a silent room. Just got this series 9 last week.

I’m having the same problem. It just started yesterday(4/23/23) and went completely crazy! I’ve had my watch for less than 6 weeks and it hasn’t had any impacts or damage, it is up to date on updates, and I’ve tried turning it off and on again.

Troubleshooting has not worked yet, so I have turned the notifications off for now. But I’d prefer to find a fix and have a working feature.

Hoping it’s just a random glitch!

My Apple Watch always reports sound levels above 90 dB during my morning training rides. However, the only sounds I hear during my rides are birds and the wind rushing by my ears. Is the watch really telling me cycling is bad for my hearing?

Please help. My Apple Watch 9 loud noise notification starts coming frequently since last week. And now it’s coming every 30 minutes even when I’m asleep. No noise at all. I called Apple and the agent advised me to turn off my notifications which I think is not right. Anything else besides taking to Apple Store 120 miles away? Thank you!

Mine started doing it the other day too! I only got it a couple weeks ago, Series 9 as well. Stuck at around 107ish. Had to turn off the notifications cause they keep going off. Hopefully it’s just a software issue. I tried recording a voice memo and that sounded fine, so it’s not the mic.

Did you get resolution for this issue? I’m having same issue and no resolution yet.
