Most digital hearing aids let you connect directly or indirectly to other electronic devices.
The available solutions depend on the hearing aid manufacturer and the specific hearing aid.
Many hearing aids can connect to other electronic devices, directly or indirectly, via Bluetooth making it possible to steam sounds, e.g. music directly into the hearing aids. The next generation of Bluetooth, LE Audio, will provide broadcasting of signals from many types of media to any user in the range of the transmitter who use hearing aids.
Other types of connectivity
Other types of connectivity are FM-systems or line-in options (mini-jack). These are typically connected to the hearing aids with a special device that sends wireless signals to the hearing aids.
Transmitters can e.g. be connected to your TV, your computer, your stereo or your radio and hereby send signals directly or indirectly into your hearing aids.
Certain devices (transmitters) can also be placed on tables or elsewhere at meetings and conferences or lectures sending the sound directly or indirectly into your hearing aids.
Smartphones and mobile phones
Smartphones and other mobile phones can often be connected to your hearing aids and wireless connection via Bluetooth becomes more and more common. When your phone is connected to your hearing aids, the signals from the phone are sent directly into the hearing aids.
An app for your phone is also often available together with the hearing aids letting you control and adjust your hearing aids via the app on the phone.
Hearing aids as headphones
Letting your hearing aids connect to your phone or other electronic equipment actually makes your hearing aids work as headphones.
T-coil and loop systems
Some hearing aids are equipped with telecoils, letting the hearing aids connect to a loop system. A loop system is a special type of sound system for people who use hearing aids. The loop system provides a magnetic wireless signal that is picked up by a hearing aid when it is set to the T-setting (telecoil).
Typically, loop systems can be found in meeting rooms, auditoriums, theatres, cinemas, places of worship and other public places.
