A newly published Apple patent reveals that the company has worked out a system that would auto-adjust the volume of the iPhone or MacBook speakers based on the levels of ambient noise.
The patent indicates that the levels could adjust based on user preferences and the presence of headphones. It might even be able to sense an echo in the room and suggest a switch to headphones or even cancel out the effect by changing its sound output. So far, there is no indication that Apple plans on doing anything with this technology, but as far as I'm concerned, it would be a welcome extension to the ambient light sensors they already use.
