Out of all the solutions which could help deaf people here, this is definitely one of the most creative things I’ve seen. Researchers from the US have developed an electric mouthpiece that can transmit sounds to people – through their tongues.

The device is also cheap, widely effective, and very little invasive. The device uses a Bluetooth-enabled earpiece to pick up sounds, then converts them into electrical signals, and then convert them into vibrations which the users can hear by pushing their tongues up.

The mechanism is fairly similar to how current cochlear implants work, except you don’t need any surgery to implement it. The new mouthpiece also doesn’t require a patient’s auditory nerve to be functional, so it can be used by virtually all people suffering from deafness or similar related issues.

“It’s much simpler than undergoing surgery and we think it will be a lot less expensive than cochlear implants,” said John Williams, a mechanical engineer from Colorado State University, who co-led the project, in a press release. Cochlear implants are very effective and have transformed many lives, but not everyone is a candidate. We think our device will be just as effective but will work for many more people and cost less.
