There are several FCC-authorized services that provide call captioning for people with hearing loss. The captioning can either be via a landline phone or a cell phone. With the landline, there is a large touchscreen that displays captions of what callers say. You can adjust the phone's volume and frequency amplification to suit your hearing needs. There is also a mobile app that provides captions for phone calls. Services and installation for the phone and app are entirely free. 

Sometimes a hearing aid alone isn't enough. Hearing aid manufacturers have developed remote microphones to help you hear better in 1:1 settings and in group environments. Remote microphones can either be worn by the person you want to hear so that their voice is brought directly to your ears, or it can be used as a table microphones to pick up close proximity voices.

Alerting devices use light, sound, or vibration to notify people who are deaf or hard of hearing when something is happening. They can be used in the home, workplace, or in public.

Hearing aids work best within 6 feet. Watching TV is one of the biggest struggles for people with hearing loss. Hearing aid manufacturers have created TV boxes that plug into your TV and stream your show directly to your hearing aids.
