How do Digital Hearing Aids Work?
Hearing aid users have often experienced frustration achieving benefit with their hearing aids for phone use, watching TV or enjoying a movie at the theater. Wireless technology offers exciting potential for use in these environments by eliminating the acoustic challenges of competing signals.
A number of wireless technologies are used in hearing aids today. Due to regulatory or power limitations (hearing aids operate with a 1.5 volt battery), hearing aid developers have developed numerous technical solutions: Near Field Magnetic Induction (NFMI) and 2.4 GHz are the most commonly used. All solutions are intended to enhance phone use, TV watching and use apps to provide the consumer more control of their hearing aids.
How does NFMI digital hearing aids bluetooth technology work?
This is technology that uses magnetic coupling to communicate a signal between hearing aids or an external device, known as a streamer. This streamer is required for various options, including volume control changes, program changes or connection to other devices. By connecting to the streamer the patient can “pair” their cell phone signal from other Bluetooth devices, such as MP3 players. These Bluetooth signals are converted to a low frequency magnetic signal. NFMI is range limited (12-18 inches) requiring the patient to wear the streamer at all times. NFMI is not found in all sizes of hearing aids today.
How does 2.4 GHz digital hearing aids technology work?
This technology is the most commonly used today. 2.4 GHz and Bluetooth are not synonymous with one another. When used in hearing aids, the most common form of 2.4 GHz technology is BLE (Bluetooth Low Energy), found in Made for iPhone® (MFI) hearing aids. These devices, typically used in a select number of hearing aids, allow the patient to stream signals directly from the iPhone to the hearing aid(s). In addition to the streaming of music and phone calls, the patients can enable an extended number of additional memory settings.
Some hearing aids work with Android phones using a technology known as Bluetooth Classic. This allow direct connection of phones to the hearing aids for streaming. If your computer, car or music player contains Bluetooth connectivity you can expect a robust connection to your hearing aids.

[H2] How does Telecoils or T-coils digital hearing aids technology work?
These are small devices installed in hearing aids. An Audio induction loop generates an electromagnetic field that can be detected by T-coils, allowing audio sources to be directly connected to a hearing aid. The T-coil is intended to help the wearer eliminate background noise and only hear the acoustic phone signal. Commonly used with telephones T-coils are also compatible with FM systems (with neck loops), and induction loop systems (also called “hearing loops”) that transmit sound to hearing aids from public address systems and TVs. Hearing loops are often used in churches, and other public places such as theaters. These hearing loops are gradually becoming more common in the U.S.
Are T-coil and Induction col is the same thing?
A T-coil consists of a metal core (or rod) around which ultra-fine wire is coiled. T-coils are also called induction coils because when the coil is placed in a magnetic field, an alternating electric current is induced in the wire (Ross, 2002b; Ross, 2004). The T-coil detects magnetic energy and transduces (converts) it to electrical energy. In the United States, the Telecommunications Industry Association’s TIA-1083 standard, specifies how analog handsets can interact with telecoil devices, to ensure the optimal performance.
Although T-coils are effectively a wide-band receiver, interference is unusual in most hearing loop situations. Interference can manifest as a buzzing sound, which varies in volume depending on the distance the wearer is from the source. Sources are electromagnetic fields, such as CRT computer monitors, older fluorescent lighting, some dimmer switches, many household electrical appliances and airplanes. https://en.wikipedia.org/wiki/Hearing_aid )
What’s the difference between wireless hearing aids and Bluetooth Hearing aids?
Wireless technology is an evolving area of technology for the hearing aid industry. Providing new utility to the patient, this technology enables connectivity to other appliances, allowing the patient to experience enhanced phone listening, TV viewing and control over volume and memory settings. Wireless should not be confused with Bluetooth, which is another form of wireless technology. For hearing aids, wireless refers to the transmission of speech, music or data between devices or external devices.
