A hearing aid playing a tune or melody is almost always a built-in notification trying to tell you something. The most common cause is a low battery alert, but it can also be a startup or shutdown chime, a program-change indicator, a tinnitus masking sound, or a notification from your phone streaming through the device. Figuring out which one takes a little detective work, but the possibilities are limited and easy to sort through.
Low Battery Warnings
The single most common reason a hearing aid plays a tune is to warn you the battery is dying. Most hearing aids use a short melody, a series of descending beeps, or a repeating chime when the battery drops below a certain voltage. The exact sound varies by manufacturer. Some brands play a recognizable three- or four-note melody every few minutes, while others use a ticking pattern that speeds up and gets louder as the battery drains further.
On devices that use disposable batteries, the warning typically kicks in when voltage drops below about 1.1 volts. At that point, the hearing aid injects small pulses that you hear as a slow ticking. As voltage continues to fall, the ticking becomes faster and louder, sometimes described as sounding like a small motorboat. Rechargeable hearing aids tend to use a cleaner melodic chime instead, often playing every 10 to 15 minutes until the device shuts off.
If the tune you’re hearing repeats at regular intervals and your hearing aid eventually dies, the battery is your answer. Replacing or recharging should stop it immediately.
Startup, Shutdown, and Program Chimes
Hearing aids also play short melodies when they power on, power off, or switch between listening programs. These are intentional audio cues so you know the device is responding to your input. A startup jingle typically plays once when you open the battery door or place a rechargeable aid in your ear. Program-change tones are usually a single beep, two beeps, or a rising sequence of notes to indicate which program you’ve switched to (program one gets one beep, program two gets two, and so on).
If you’ve accidentally pressed the program button on your hearing aid, you may hear a chime and notice the sound quality changes slightly. This is normal. Pressing the button again cycles to the next program, and most aids loop back to the default after the last one.
Tinnitus Masking Sounds
Some hearing aids have a built-in tinnitus sound therapy feature that plays gentle background sounds. If this was activated during your fitting, possibly without you realizing it, you might hear what sounds like wind chimes, ocean waves, soft static, or other ambient tones. These aren’t exactly “tunes,” but wind chimes in particular can sound musical enough to be confusing.
Common tinnitus masking profiles include white or pink noise, running water, rain, and wind sounds. The American Tinnitus Association notes that these work by giving your brain something neutral to focus on instead of the ringing. If you’re hearing a continuous, looping ambient sound rather than a short repeating melody, a tinnitus masker is the likely culprit. Your audiologist can check whether this feature is turned on and disable it if you don’t want it.
Phone Notifications Streaming Through
Modern Bluetooth hearing aids connect to your smartphone, and that connection doesn’t just carry phone calls. Text message tones, app alerts, keyboard clicks, and even lock sounds from your phone can stream directly into your hearing aids. If the “tune” you’re hearing matches your phone’s notification sound, this is almost certainly the cause.
You can stop this without disconnecting your hearing aids entirely. On an iPhone, go to Settings, then Sounds & Haptics, and turn off keyboard clicks and lock sounds. For other notification tones like texts, tap the specific alert and set it to “None,” which switches it to vibrate only so the sound no longer reaches your hearing aids. If you use your hearing aids only for phone calls and don’t stream music or podcasts, there’s a more thorough option: go to Settings, then Accessibility, then Hearing Devices, then Audio Routing, and set Media Routing to “Never Hearing Devices.” This blocks all media audio, including notification sounds, from streaming through.
Android phones have similar options under their Bluetooth and accessibility settings, though the exact path varies by manufacturer.
How to Figure Out Which One It Is
A few quick checks can narrow it down:
- Timing matters. A sound that repeats every few minutes and eventually leads to the hearing aid shutting off is a low battery warning. A sound that plays once when you insert or remove the device is a startup or shutdown chime.
- Check your phone. Put your phone in airplane mode for an hour. If the tune stops, your phone notifications were the source.
- Listen for a pattern. A continuous ambient sound like static or running water points to a tinnitus masker. A short, distinct melody points to a system alert.
- Press the program button. If pressing it produces the same tune you’ve been hearing, you’ve been accidentally switching programs.
If none of these explanations fit, the hearing aid may be malfunctioning. Moisture damage, firmware glitches, or a failing speaker can occasionally produce unexpected sounds. Your audiologist can run diagnostics, update the firmware, and check whether any features were accidentally enabled during your last adjustment.
