Speaker Test
The speaker test plays isolated tones through your left and right channels so you can hear exactly what each speaker is doing. Press play above. You will hear a tone on the left, then on the right, then on both together. Listen carefully to each one.
When to use this test
Run the speaker test when you are not sure what is wrong. It answers three questions quickly: does each speaker produce sound, does it sound clean, and is one side weaker than the other.
It is also the best way to confirm a fix. Run the test before cleaning, then run it again after. If the tones sound clearer and more balanced, the cleaning worked. If nothing changed, the problem may be deeper than a surface blockage.
How to read the results
- Both sides clear and equal. Your speakers are healthy. If audio still sounds wrong in a specific app, the problem is software or the audio file itself.
- One side muffled or quiet. That speaker has a blockage. Run water eject if water was involved, or the dust cleaner if the decline was gradual.
- Crackling or buzzing on one side. Debris may be touching the membrane, or the membrane may be damaged. Try cleaning once. If the distortion stays, the speaker is likely damaged.
- One side completely silent. This points to hardware failure. No cleaning tone will fix a dead speaker.
A note on phone speakers
Most phones have two speakers that work as a stereo pair: the bottom speaker and the earpiece. On the test, “left” and “right” map to these two speakers. That is also why the earpiece cleaner exists as its own mode. If the test shows the earpiece channel is the weak one, clean it directly.
