FAQ – FM Systems

Are hearing aids enough or do children also need FM systems?

Some hearing aid users find that the sound quality has improved and the background noise reduced so that they no longer feel they need the assistance of a personal FM system. However, an FM system still has huge advantages in a classroom over hearing aids alone. Using the FM system reduces the effects of reverberation (echo) and distance between the teacher and child that are still difficult for a hearing aid alone to cope with.

At what age should my child start using FM?

FM can be crucial to your child’s development from a very early age if they are facing noise, reverberation and hearing from a distance. Although experts recommend introducing the use of FM when the child starts being mobile it basically depends on when the family is ready, which can be as early as six months.

My child wears two hearing aids, so should he wear two FM receivers?

Scientific evidence shows that transmission to both ears brings significant benefits, and scientific data shows that speech understanding improves 40% when two FM receivers were used instead of one (Valente, Enrietto, Crandell, Lewis (2002)).

Is it possible to use FM systems with the cochlear implant?

Yes, that is possible. Individuals with cochlear implants experience the same difficulty as hearing instrument users in challenging listening environments. The Phonak receivers are available in different configurations depending on the speech processor. Click here for more information about FM systems for children.

What is the difference between an FM System and an Infra-red system?

Infrared systems use infrared light to transmit the audio signal. When this light is blocked, the signal cannot be heard. Thus, infrared systems are susceptible to people and objects getting in the way. Also, infrared systems do not work in sunlight. FM systems can transmit through objects and operate as effectively in sunlight as they do indoors. FM systems require no installation. Click here for more information about FM systems for children.
