Hearing aids play tunes, chimes, or melodic sequences as intentional alerts to tell you something specific is happening. The most common reason is a low battery warning, but your device may also be signaling a program change, a volume limit, a startup or shutdown sequence, or even playing therapeutic sounds designed to help with tinnitus. The good news: a tune (as opposed to a whistle or screech) is almost always a built-in feature, not a malfunction.
Low Battery Warning
The single most common reason for an unexpected tune is your hearing aid telling you the battery is about to die. Most modern hearing aids play a repeating sequence of beeps or a short melody when power drops below a certain threshold. Think of it as a gentle countdown. Depending on your model, you may get anywhere from a few minutes to about 30 minutes of use after the first alert before the device shuts off completely.
Some devices use a voice announcement (“battery low”) instead of or alongside the melody. Others pair the audio alert with a notification pushed to your smartphone app or an LED light that changes color. If you use rechargeable hearing aids, the same kind of alert plays when the charge is running low.
Program and Volume Changes
If you pressed a button on the hearing aid (or tapped something in the companion app) right before the tune played, that melody is simply confirming your input. Hearing aids with multiple listening programs, like a quiet-room setting versus a noisy-restaurant mode, play a distinct beep or short chime each time you switch. A single beep might mean Program 1, two beeps Program 2, and so on. Similarly, adjusting the volume can trigger a tone when you hit the maximum or minimum level, letting you know you’ve reached the end of the range.
Startup and shutdown sequences work the same way. Many hearing aids play a brief ascending melody when they power on and a descending one when they turn off. If you’ve just inserted a fresh battery or placed a rechargeable aid in your ear, that cheerful little jingle is the device saying it’s ready.
Tinnitus Sound Therapy
Some hearing aids include a built-in sound therapy program that plays gentle, chime-like tones to help manage tinnitus. If your audiologist activated this feature, that could explain the tune you’re hearing. The most well-known version is Widex’s Zen program, which generates what are called fractal tones: harmonic, melodic sounds that resemble wind chimes. These tones are deliberately unpredictable, meaning they never repeat in a recognizable pattern. That unpredictability is the point. Because your brain can’t latch onto a repeating loop, it shifts into passive listening mode, which over time can help you become less aware of the ringing or buzzing of tinnitus.
A clinical pilot study found that fractal tones, combined with amplification and relaxation strategies, improved tinnitus severity scores in participants. If you didn’t know this feature was turned on, or if your audiologist enabled it during a fitting and you’ve forgotten, it can be startling to suddenly hear random chimes. Check your hearing aid app or ask your audiologist whether a tinnitus management program is active on your device.
How to Tell a Tune From Feedback
A tune or melodic alert sounds deliberate: it has a clear rhythm, repeats in a pattern, or plays a recognizable sequence of notes. Feedback is different. It’s a high-pitched whistle or squeal caused by amplified sound leaking out of your ear canal and getting picked back into the microphone. Feedback is continuous or fluctuates with jaw movement, and it has no musical quality at all.
There’s also a subtler version called sub-oscillatory feedback, which can produce odd overtones or a tinny quality in speech without a full-blown whistle. If what you’re hearing sounds harsh, wavery, or whistle-like rather than melodic, the issue is probably a poor fit, a cracked tube, or earwax buildup rather than an intentional alert. A quick check: remove the hearing aid and reinsert it snugly. If the sound stops, it was likely feedback caused by a loose seal.
Adjusting or Silencing Alert Tones
Most manufacturers let you customize alert sounds through their companion app or through your audiologist’s programming software. Depending on the brand, you may be able to change the volume of alerts, switch between tones and voice announcements, or turn off certain notifications entirely. If your hearing aid connects to an Android or iPhone, be aware that Bluetooth streaming can sometimes route phone notification sounds directly into your hearing aid, which might sound like an unfamiliar tune. Checking your phone’s notification settings and the hearing aid app’s streaming preferences can help you isolate whether the sound is coming from the aid itself or from your phone.
If you can’t figure out which alert is playing or why, the fastest fix is to bring the device to your audiologist. They can pull up a log of recent activity on the hearing aid, confirm which programs are active, and adjust or disable any alerts that are catching you off guard. They can also check for firmware updates, which occasionally fix bugs related to unexpected sounds.
