In an article published in the American Journal of Audiology, Professor Linda Thibodeau (University of Texas) describes her findings on new wireless technology which places people with hearing loss in better conditions for hearing and understanding than normal-hearing persons. This becomes evident in certain circumstances: with background noise and at a distance. This advantage for the hearing-impaired over the normal-hearing, with both factors influencing hearing, climbs to 62% and over, according to sources at Phonak. The results of these measurements were obtained through speech recognition comparison tests - in groups of children and adults - and using different wireless technology, such as fixed and fitted FM, or the new type of devices called "Roger".

With a noise level of 65 dB or higher, persons with hearing aids using Roger obtained better speech recognition than those who were not fitted. A team of more than 40 engineers and audiologists worked together more than seven years on the the Roger invention at the Phonak head office in Switzerland. This device is a new wireless digital standard which helps hearing aid users to understand 62% more (with noise and distance) than the normal-hearing through microphones designed to capture and transmit the voice of your interlocutor through miniature 2.4 GHz receivers.
