Roger™ wireless technology by Phonak Brand Hearing Company
Speech intelligibility is key for effective communication. Factors that affect speech intelligibility, include background noise level, distance away from the speaker, acoustics of the environment, and reverberation.
In situations where these factors affect the signal-to-noise ratio (SNR), understanding speech can still be challenging. Hearing aids provide the most benefit when a speaker is within 1.5 meters/5 feet of the listener. As soon as the noise increases and the distance between the listener and speaker becomes greater, additional technology is needed to maintain speech intelligibility and understanding while overcoming both distance and noise.
This is where Phonak's Roger Clip-on microphone comes in to boost hearing aid performance. Roger microphones have been developed to reduce background noise and transmit the speaker’s voice directly to hearing aids or cochlear implant sound processors.
RogerDirect allows Roger microphones to stream directly to the hearing aids. After the installation of the receiver into the hearing aid, people will benefit from the proven performance of Roger, in noise and over distance1.
Phonak's Roger technology makes use of intelligent and adaptive algorithms that continuously measure and precisely analyze noise levels to keep the Roger signal clearly audible above the background noise.
MultiBeam Technology enables people to experience better speech understanding in group conversations such as business meetings or in noisy restaurants.
By utilizing multiple microphones, beams are created in six directions, covering 360°. It then calculates and compares the signal-to-noise ratio for all six directions and automatically selects the beam with the best clarity.
Unique to Roger and fully automatic, the MultiTalker Network allows several Roger microphones to be used together, providing people who have hearing-impairment with access to multiple talkers in any situation.
