Great tip! I'm an electrical engineer who has followed hearing aid technologies for 20 years and was wondering how Artificial Intelligence (AI) has been applied to hearing aids especially to improve performance with noisy backgrounds like a big busy restaurant etc. Even normal hearing individuals will eventually benefit more and more from human sensor assist technologies that can literally make us super human. Many animal and insect species have better hearing and vision capabilities than humans. Likewise, today's robots are already performing "super human" tasks. Just think of how this $500 a pair competition into state of the art hearing aid technology is going to make the big $5,000 a pair hearing aid companies sit up and take notice! The Over The Counter (OTC) hearing aid revolution is indeed in full swing and can only benefit all of us in the future.
