As the title says, I’m just wondering if it’s a hidden feature? Today there’s a lot of police van rushing (because of the protests going on here in Hong Kong) with loud sirens. And my left ear, Where I can hear the siren, it automatically turn off the transparency mode. Or it’s just a coincidence?

I’m gonna say coincidence. This is not a feature as far as I’ve heard. There are hearing protection devices that do exactly this, but APP isn’t one of them.

This would be a good feature. Say youre jogging or biking and there are sirens/horns behind you. It'd behoove you to hear those....itd be a good safety feature. Following this....

Yes, it is a feature. Every morning when I am standing on the train platform, large cross country trains blow by me and every single time the transparency mode cuts off in my closest ear (not sure if full ANC turns on or not).

It's odd that you mention this, I had my AirPods in transparency mode on the central line tube this morning and noticed at a particularly screechy bit of track it switched to NC mode, it didn't switch back however.
I will see if it does it this evening too, or if it was some form of glitch coincidentally.

It absolutely does seem to automatically protect your hearing from the loudest noises on a per-ear basis (from my experience all over NYC). Would love for Apple to release a bit of info on the details of this function and then an adjustable limiter threshold in Settings. Personally I’d like it to kick in a little sooner and I’d also love to be able to adjust the volume of Transparency Mode.

Seems strange if this is true - If Apple are protecting your hearing by doing this, then why haven’t they added seperate notification alert volume over Bluetooth...We’re still forced to lower the ringer volume because if we leave it on full, then your ears are at risk of damage when a message etc. comes through whilst using the AirPods...

Perhaps this is more to do with protecting the microphone then your ears? Seems like maybe it auto shuts off to protect the mic

If this is true, and I have noticed it on multiple occasions, wonder if it uses the decibel level from the noise meter app. I’ve had that turned on since day 1. Anyone get this phenomenon without having noise meter on?

Do you mean the Noise db meter App? My AirPods Pro have been auto enabling ANC when a high pitch noise is detected without the Noise meter App for a while now.

I think it is a feature either intentional or unintentional because it could be for something like preventing the airpods playing loud sounds through transparency so it doesn’t hear itself then echo or so it can use the microphones inside better. But this does happen for me quite a lot and I like the feature isolating me from the noise for sake of hearing health.
