Assistive listening devices are devices that can help a listener function better in day-to-day communication situations. ALDs can be used with or without hearing aids to make hearing easier, which can reduce the overall stress and fatigue of listening. ALDs can be used in the home to make alarms, televisions and telephones more audible. They can also be connected to personal hearing aids for better listening in noisy environments. Systems can also be set up in school classrooms and places of worship. Many buildings such as theatres and auditoriums in Colorado are beginning to set up looping systems that can connect to the telecoil in your hearing aids to provide the amplified sounds directly to your ear.
