What is actually happening
The squeal is the hearing aid itself. A hearing aid is a tiny microphone and speaker sitting in the ear. When amplified sound leaks back out and into its own microphone, it feeds back and whistles. Loud sound in the room, a hand or hymnal near the ear, or an aid pushed to its limits by a loud system all make it more likely. It can also simply over-amplify a loud moment until it distorts.
The echo and muddiness come from the room. In a sanctuary with hard surfaces and a tall ceiling, sound keeps bouncing for a second or more after it is spoken. A hearing aid’s microphone, sitting in the pew, picks up all of it — the reflections, the air conditioning, the rustle of bulletins — and amplifies it along with the sermon. A person with hearing loss has a harder time separating the words from the reverberation than everyone else does.
Turning the main system up does not help them. It adds more of the same echo and makes the squeal worse.
What fixes it
What actually helps
A hearing loop to the hearing aid’s “T” setting
A hearing (induction) loop is a wire around the seating area that carries the sound from the sound board as a magnetic signal. Hearing aids and cochlear implants with a telecoil pick it up directly when switched to the “T” or telecoil setting — no room echo, no squeal, just the microphone feed. Many hearing aids have a telecoil, but not all, and an audiologist sometimes needs to turn it on.
Auracast for newer hearing aids and phones
Auracast is Bluetooth LE Audio broadcast. The sound board’s feed is broadcast in the room, and newer hearing aids, earbuds, and phones that support it can tune in directly. It is newer, so it works for some members today and more each year.
RF or IR receivers with earbuds
For members without compatible hearing aids, a small radio-frequency (RF) or infrared (IR) receiver with earbuds or headphones delivers the same clean feed. Receivers are kept at the welcome desk and handed out each service.
Better speaker coverage and acoustic treatment
Speakers aimed at the seats instead of the walls, and acoustic treatment where the room is hardest, reduce echo for everyone — including members with hearing aids who do not use a receiver.

Choosing an assistive listening option
There is no single right answer for every church. These are the questions that decide it, and we’ll help you choose the right option.
- 1
Ask who needs it
Find out how many members wear hearing aids or cochlear implants, and whether their devices have a telecoil or support Auracast. Their audiologist can tell them.
- 2
Look at the room
Loops depend on the building’s structure and seating layout; IR needs line of sight; RF and Auracast pass through walls. The room shapes the choice.
- 3
Plan for people without compatible aids
Whatever the main option, keep a few receivers with earbuds or headphones at the welcome desk for those who need them.
- 4
Feed it from the sound board
Every option sends the board’s mix straight to the ear, so the microphones and the mix matter. A clear speech mix is the foundation.
- 5
Tell people it is there
Post the symbol at the doors, mention it in the bulletin, and have greeters offer a receiver. A system nobody knows about helps nobody.
Why it matters
How it serves your mission
The members most affected are often the ones who have been in those pews the longest. Helping them hear again is not a technical upgrade; it is honoring the people who built the church.
Churches are generally not required to provide assistive listening — religious organizations are largely exempt from the ADA’s public-accommodation rules. Churches do it because they love their members and want every one of them in the room and hearing the word.

“I didn’t even know what to ask at first, but [the team] was so patient and walked me step by step through the process of installing a complete AVL system in our building after it was rebuilt from tornado damage. They were understanding, trustworthy, and respectful the whole way through. Today, we have an amazing AVL system that goes far beyond my expectations.”
