Babelfisk: A Visual Hearing Aid

We’ve covered variousdesignsolutions for the vision-impaired. But what about the hearing-impaired? While the sight is visual in nature and thus more organically linked to design, can the auditory sense be addressed through this inherently visual medium?

Babelfisk, an ingenious concept device by Danish designer Mads Sukhdev Hindhede, aims to do just that. The sleek hearing aid is housed in a pair of glasses, which use a receptive “listening” process to transcribe conversations in the surroundings as text messages displayed in the user’s line of sight. Two microphones affixed to the sides of the frames filter speech and embedded translation software display it as text via two projectors. The visualization also allows users to sense where sound is coming from, adding a layer of organic spatial orientation to the listening experience.

While merely a concept, Babelfisk offers an exciting vision for an intelligently designed, synesthetic approach to auditory disability.
