I was reviewing Apple's documentation regarding security and unauthorized tracking devices, which included the [following statement](https://support.apple.com/en-us/119874): 

> If any AirTag, AirPods, Find My network accessory, or compatible Bluetooth location-tracking device is separated from its owner and seen moving with you over time, you're notified in one of two ways: a notification on your device, or a sound emitted by the device.

This anti-stalking feature is triggered when the device is both separated from its owner and seen moving with another person over time. What are the distance and time criteria for an AirTag or Find My Accessory to emit an anti-stalking sound?
