Picking up good vibrations

A device that enables individuals who are deaf and blind to distinguish between different sounds through vibration has been developed at Örebro University in Sweden.

The aid, named Monitor, works by registering sounds through a microphone and converting them to lower frequencies via a processor. This allows the human skin, which cannot sense frequencies higher than 800Hz, to perceive a wider range of vibrations. Parivash Ranjbar, computer engineering researcher and the system’s inventor, claimed the device has even allowed subjects to understand what is being said in a conversation.
