That said, some noise cancelling headphones offer modes that specifically let road noise through, and folks have hacked them to improve directionality of weak sound signals, and amplify voices. The Parrot Zik firmware comes stock with a 'street' mode. It's entirely possible to have these systems function as hearing aides. MIT lab folks have demoed small wide-angle optical object detection that's then translated to directional feedback in a haptic belt.
