Phonak’s FM systems improve the signal–to-noise ratio and thus the user’s ability to understand speech in noise. Three major factors that influence the signal-to-noise ratio and the quality of the speech signal are: background noise, reverberation and distance. By delivering the signal of interest via FM (radio waves), the strength and quality of the sound remains constant across the distance from the speaker to the hearing impaired individual.
FM systems consist of a transmitter with a microphone, and a receiver, which picks up the signal via radio waves directly from the transmitter. Cochlear implant recipients experience similar difficulties to hearing instrument users in challenging environments. It is well documented that improving the signal-to-noise ratio (SNR) for cochlear implant recipients through the use of an FM system significantly improves speech recognition in the presence of background noise. In recent years Phonak has developed the most extensive FM product portfolio on the market. Phonak’s Dynamic FM products boost speech intelligibility to levels never seen before.
Recent scientific research clearly indicates that Dynamic FM also brings these
benefits to Cochlear implant recipients. Well over 60% of all children with a cochlear implant use an FM system. A rapidly increasing number of adults also benefit from an FM system used in combination with their cochlear implant.
A very useful online tool is the FM Configurator, which can be found in our downloads section, where you will also find the latest set-up tips.
FM is not a luxury for Cochlear implant recipients, but increasingly a necessity. At a fraction of the cost of the Cochlear implant, an FM system offers an incredible performance enhancement. We encourage you to systematically fit FM systems to all children and adults with cochlear implants. Candidates should ideally be informed about FM systems prior to implantation.
