AirPods Pro 2: ANC after 5B58 update?

[scrane]

However, Apple claimed that the APP2 can cancel up to twice as much noise as the APP1. So, instead of showing a 30db reduction, I should expect the Noise app to show a 60db reduction, right?

33 dB.

No, as decibels are not linear You don’t need 60db reduction in order to have twice the sound / noise reduction of 30db.

Besides, the Max are clearly superior in ANC compared to the APP1. But I guess it won’t take long to have people claiming otherwise here

While sitting in my otherwise dead-silent room with a Dyson air filter running, the WatchOS Noise app indicates that my APP1s reduce the noise by 30db, while my AirPods Max reduce the noise by 29db. But I can clearly hear the hum of the air filter while wearing my Pros, and barely at all while wearing the Max.

From that, I can conclude the APP1 and Max have basically the same ANC technology, and it's just the over-the-ear nature of the Max that makes them seem more effective than the APP1.

The Decibel is a logarithmic unit. So an increase of 2x in noise cancelling means -3Db of reduction.
Check it out here.

A reduction of 33 dB in your APP1 is huge. It is the same amount that the APP2 cuts before the firmware update. Now the APP2 cuts 24 dB.

Thanks, everyone, for helping me understand this. I appreciate it being explained to me.
