**2.4 Hearing Assistive Technology Systems**

Other devices are employed to assist individuals with hearing impairment who have not previously experienced benefit with hearing aids or cochlear implants alone. Hearing assistive technology systems (HATS) are devices that can help patients function better in their day-to-day listening and communication situations. HATS can be used with or without hearing aids or cochlear implants to make hearing easier—and thereby reduce stress and fatigue. HATS must be directed toward resolving any one of the following situations: distance; noise, or reverberation that can create listening problems (Medical Services Advisory Committee, 2010).
