There have been a ton of videos in recent years of people who are able to hear for the first time in their lives and their reactions to hearing their own voice, or other people's voices, but this one might be my favorite so far. Ken Stehle has been deaf for over 50 years, but with some help from new technology, he heard his daughter sing for the first time last weekend.

Ken's 15-year-old daughter Ashley had a Christmas concert for her school choir in St. Louis, MO on Sunday, and that was when Ken got to hear something he never thought he would - his daughter singing.
