A small coil inside the hearing aid that picks up sounds directly from compatible phones and hearing loops. These may be used in public places, such as concert halls and theatres.

Telecoil in detail

Telecoil or t-coil is a wireless feature that receives and converts electromagnetic signals generated by compatible telephones and rooms with audio induction loops. Because the signal of interest is directed to the hearing aid’s processor without using the microphone, a telecoil can improve the signal-to-noise ratio while eliminating the potential for feedback. Public performances, tours, exhibits and worship services are commonly made accessible to individuals with hearing loss via hearing loop and telecoil.

Intended Purpose:
Speech Understanding

Look out for these words: T-coil, Audio induction loops.

Mobile Phone and Device Connectivity

Connect your hearing aids with Bluetooth® devices. May be used for phone calls, audio streaming and hearing aid control.

Mobile Phone and Device Connectivity in detail

Streaming technologies (e.g. Made for iPhone (MFI), Made for Android, and Bluetooth) allow the wearer to connect and stream audio and phone calls using their smartphone, television and other consumer devices. Wearers can pair their streaming-enabled hearing aids to consumer devices using standard Bluetooth.

Intended Purpose:
Speech Understanding
Sound Quality

Look out for these words: Streaming, Made for iPhone (MFI), Made for Android, Bluetooth.

Accessory Connectivity

Links your hearing aids to hearing aid accessories. This can include remote microphones and TV streamers.

Accessory Connectivity in detail

Accessory connectivity provides wireless connectivity to accessories that can provide benefits such as improve audibility and provide additional functionality. For example, a remote microphone for improving audibility in noisy environments, a control accessory that allows a facilitator to adjust settings for multiple hearing aids simultaneously, or a TV streamer for streaming television audio directly to a hearing aid.

Intended Purpose:
Speech Understanding

Look out for these words: App connectivity, Bluetooth, Streaming, TV streamer, Remote control.

Phone Assistive Technology

Detects when a phone is being used and adjusts hearing aid settings for you.

Phone Assistive Technology in detail

Phone assistive technology detects when a phone is held up to the ear and activates a phone streaming program. There are two standard phone detection methods: inductive and acoustic. The inductive phone detection method requires a hearing aid with a telecoil and operates by detecting the magnetic field produced by a stationary phone handset or a small magnet located on a handset or mobile phone.

The acoustic phone detection method uses the hearing aid microphones to detect the acoustic signature associated with a phone held in close proximity to the ear. In the case of both methods, when the hearing aid detects that a handset is in close proximity to the ear, the hearing aid switches to a special phone program, which may reduce the gain of the opposite ear and/or stream the phone conversation to both ears.

Intended Purpose:
Speech Understanding

Look out for these words: Automatic phone detection, Telephone mode, Telephone program.
