The volume of alerts in the future iPhone could regulate itself according to the ‘noise’ outside. This technology, in which Apple Watch plays a key role, is described in Apple’s new patent.

The patent technology ” Volume control for mobile devices using a wireless device ” is to be implemented in a wearable device (hard not to think of Apple Watch).

  
With this system, Apple Watch is able to perceive the outside noise and automatically adjusts the volume of alerts on iPhone. In quiet environments, not to annoy other people, turn the volume down, in noisier environments is raised instead. The Apple Watch microphone records all the information necessary to control and sends them to the smartphone that automatically sets the volume of notifications.
