Varibel, Hearing Aid GlassesEngineers at Delft University of Technology in the Netherlands have developed glasses that include microphones for amplifying sound.
The glasses use a group of four microphones on the sides of the glasses to focus the sound reception to where the user is looking.
The eyeglass hearing device has two distinct improvements over traditional hearing aids. First, there is no apparent apparatus. The amplifiers are completely contained in the glasses frame. Second, the multiple microphones and processing allow the most amplification for sounds where the person is looking while reducing the surrounding noise. This greatly improves the ability to communicate with others.
