Run a quick left/right stereo test, a 20 Hz–20 kHz frequency sweep, or pink/white noise to diagnose rattles and crackle. Works on iPhone, Android, laptops, and desktop speakers—no app needed.
Quick start
Start low, then raise to a comfortable level. Avoid max volume for long periods.
Try tones, sweep, or noise. Use Left/Right to isolate each speaker.
Buzzing, crackle, or imbalance can indicate damage or debris.
How to use the speaker test
Use Quick Tones to target bass, mids, or treble. Try Sweep to scan the full range, or Pink/White Noise to reveal rattles.
Compare Left and Right. Use the balance slider if one side sounds quieter or thinner.
Use both the page Volume and your device’s physical volume. Avoid clipping.
Buzzing at specific frequencies → loose parts. Constant crackle → damage. Weak treble → blocked grille.
Troubleshooting & next steps
- Nothing plays? Make sure Silent/Do Not Disturb is off and your device isn’t muted.
- Only one side works? Use Left/Right buttons. If one side is always silent, hardware may be faulty.
- Crackle at low volume? Dust or moisture in the grille is common—clean gently and retry.
- Hiss on noise tests? Some hiss at high volume is normal; compare both channels.
- Power off your phone first.
- Use a soft, dry brush—no liquids.
- Compressed air in short, angled bursts.
- Re-run tones at 200 Hz, 1 kHz, 10–14 kHz.
- iPhone: Bottom + earpiece form stereo; test both.
- Android: Some boost bass; check 60–200 Hz for rattles.
- Laptops: Try 400–5k Hz; listen for chassis resonances.
- Eject water from iPhone speaker if sound is muffled after a splash.
- Record a short sample and compare channels.
- If one side stays silent, visit a repair shop.
