Varibel: glasses that aid in hearing

A recent innovation from Delft University of Technology in the Netherlands unveiled a new hearing aid called Varibel on Friday. The device, which resembles a pair of glasses instead of a traditional in-ear aid, has a directional sensitivity of +8.2 decibels, versus regular hearing aids’ maximum sensitivity of +4 dB. Each leg of the glasses’ frame has a row of four tiny, interconnected microphones that intensify selected sounds coming from the front while simultaneously inhibiting the magnitude of the surrounding noise. This allows people with hearing deficiencies to hear things from the direction in which they are looking. More research needs to be done before the glasses are fully marketable.
