The patent, entitled “Volume control for mobile device using a wireless device”, describes how Apple could use the Watch to automatically adjust the volume or other settings of the host device (in this case the iPhone) based on ambient sound samples.

According to the description, the Apple Watch could use its built-in microphone to sample ambient sound at intervals specified by the iPhone. Based on the information it collects, the Watch would be able to adjust the volume of the handset, a feature which could be very handy in certain situations, such as when you have a business meeting and you accidentally forget to silence your iPhone. Or you can imagine the opposite as well: You get out of the meeting and forget to adjust the ringer volume.

As detailed in the patent description, the iPhone sends a notification signal to the Watch, before playing an audible alert. The wearable then listens for the incoming tone and compares the signal against a stored ambient noise signal and, depending on the data it gets, adjusts the iPhone’s output volume.

While this patent application doesn’t necessarily mean we will see this implemented in future models, it would be a nice feature.
