Every hearing aid has a microphone, and for most everyday listening that built-in microphone does the job. A remote microphone is a different idea: a second microphone that lives somewhere else, closer to the person talking, and sends what it picks up to the hearing aids. This article is a plain-English look at how that works and how it sits alongside a few other accessories with similar-sounding jobs. It is written as general interest, not as guidance for any individual.
The Built-In Microphone and Its Limits
The microphones inside a hearing aid sit on the device, at the ear. That means they pick up whatever reaches the ear, including the voice you want to listen to and everything else in the room. Hearing Australia notes that hearing aids and cochlear implants work well over a distance of around one to two metres, which is simply a fact about how sound spreads out and mixes with background noise as it travels.
A remote microphone is built around that fact. Instead of waiting for a voice to travel across a room, the microphone is placed near the voice itself.
How a Remote Microphone Works
Hearing Australia describes a remote microphone system as having two parts. One is a transmitter microphone, worn by the person speaking or placed on a table. The other is a receiver that picks up the transmitter's signal and passes it to the listener's hearing device. Depending on the system, the receiver may connect directly to the hearing aid, be worn around the neck, or be a small unit attached to the aid.
Hearing Australia says that these systems may help a person hear over a distance of up to 10 metres and in background noise. That figure is a general statement about the technology, and the exact range of a particular product is set out in the manufacturer's documentation.
Some hearing aid manufacturers also make a small wireless microphone that streams a speaker's voice straight to compatible hearing aids over a wireless link. Hearing Australia refers to this kind of product as a streamer microphone. The names vary between brands, so product literature is the place to check what a given device is called and which hearing aids it works with.
Where You Will Hear Them Mentioned
Hearing Australia notes that lots of children use these systems in classrooms, and says they can also be used in other noisy situations such as in the car, for certain sports and, for some older clients, in the workplace. Its accessories page also mentions restaurants and shopping centres. These are descriptions of typical uses, and they do not say what will suit any one person.
How It Differs from a Hearing Loop and a Telecoil
A remote microphone belongs to the listener and goes wherever they go, carrying the voice of whoever is near the transmitter. A hearing loop belongs to the venue. See our articles on hearing loops and the telecoil for how those work.
How It Differs from a TV Streamer
A remote microphone carries a live voice, while a TV streamer carries the sound from a television. Our article on how TV streamers for hearing aids work covers that accessory.
A Quick Comparison
- Built-in microphone: picks up sound at the ear.
- Remote microphone: picks up a voice near the transmitter and sends it to the hearing aids.
- Hearing loop with telecoil: a venue-based system, covered in the articles linked above.
- TV streamer: carries television sound, covered in the article linked above.
Compatibility and Product Documentation
Remote microphones are not interchangeable between brands in the way a pair of headphones might be. Wireless systems are often designed by a manufacturer to work with that manufacturer's own hearing aids, and some work with a wider range of devices. The product information for both the microphone and the hearing aids sets out which combinations are supported. Accessories are one part of the wider topic of assistive listening devices, and our overview of hearing aid solutions covers the main device types.
Understanding where a remote microphone fits makes the vocabulary of hearing technology a bit less confusing: one accessory brings a person's voice closer, another carries a venue's signal, another carries the television.
