FM systems designed for hearing assistance, work similarly to commercial FM broadcast systems. A specific designated range in the FM broadcast bandwidth can be used for auditory assistance applications. Since each audio assistance system may use its own broadcast frequency, several systems can operate simultaneously at one location without interfering with each other. UAA offers both narrow-band and wide-band FM systems. To alleviate potential interference issues, all of our systems feature field tuning. UAA offers several listening options for FM receivers, including Under-chin and Walkman style headsets.
