“Assisted listening devices are actual non-hearing aid devices that help people hear in certain situations. One example is an amplified telephone that rings louder so people with hearing problems can hear them.
Another is an extra loud alarm clock or a device that allows a doorbell to turn your lights on and off. If they have trouble hearing, they could then see the change in light and know that someone is at their front door.
These are adjuncts to people’s hearing loss, if they wear hearing aids, and can help them in certain situations where hearing aids aren’t able to provide them enough benefit.”
