Hearing loss is absolutely a daunting thing, but also a lonely experience. Recently, scientist Frank Swain discovered a strange phenomenon that deaf people can hear the buzzing of WiFi signals.
In New Scientist magazine's article on WiFi signal, designer Daniel & middot; Jones builds a WiFi voice conversion tool. This project is called phantom terrain. This device can translate sound into WiFi signal, each Wi Fi signal can be encrypted by data rate, and then transmitted to people with hearing problems. This device is more likely to be used in the field of hearing aids.
