Clarity Ensemble is designed to help those with severe hearing loss and low vision by amplifying the incoming sound up to 50 decibels, as well as displaying the conversation on a large seven inch tablet-based display, allowing the user to read what is being said in real time. The Ensemble also features ClarityLogic, which allows a Clarity representative to remotely adjust your settings for you. Captioning is free, but does require land line phone service and high speed Internet.
