The 2nd generation AirPods Pro come with Adaptive Audio, which changes noise cancellation depending on the appearance. Apple Vice President of Communications Ron Huang spoke in detail about how this feature was developed.
Early in the development of Adaptive Audio, Apple used iPhone GPS data to detect when a user was in a noisy environment to switch between noise-canceling modes. For example, when outdoors, AirPods Pro automatically switched to transparency mode.
In the early stages of developing Adaptive Audio, we primarily focused on noise reduction versus transparency based on where you are. You can imagine the phone prompting the AirPods and saying, “Hey, you’re home.”
Ron Huang, Apple Vice President of Public Affairs
The company abandoned the use of GPS because the data received was not always processed.
After everything we learned, we decided that this was the wrong way to go and we did something different. Of course, your home is not always quiet, and the streets are not always noisy. We decided that instead of relying on location cues from your phone, AirPods would monitor their environment in real time and make smart decisions on their own.

Now, to set up AirPods Pro Adaptive Audio, use the microphones to detect the ambient and track volume. Depending on this, the headphones themselves regulate the level of noise reduction, balancing between transparency and complete noise reduction. [TechCrunch]
