Quick answer
Distortion is easier to identify when it repeats across different sources. One file may itself be clipped or heavily processed, so compare speech, music and generated tones.
Test at a moderate level and increase gradually. If the noise appears around the same frequency range, that pattern is more useful than simply turning the volume up.
Common causes
How to separate distortion caused by volume, source, debris or moisture from a symptom that appears across different tones.
- Volume too high for a particular signal
- A file or video that is already distorted
- Debris or moisture
- An app or audio-output issue
- Persistent physical damage
What to check step by step
- Try speech or a simple tone.
- Repeat at low, medium and slightly higher levels.
- Change app and source.
- Use the distortion test to look for a repeatable pattern.
- If it persists across content, stop pushing the speaker.
How to test it online
Test at a moderate level and increase gradually. If the noise appears around the same frequency range, that pattern is more useful than simply turning the volume up.

How to interpret the result
Distortion is easier to identify when it repeats across different sources. One file may itself be clipped or heavily processed, so compare speech, music and generated tones.
Test at a moderate level and increase gradually. If the noise appears around the same frequency range, that pattern is more useful than simply turning the volume up.
What to avoid
- Do not insert needles, clips or objects into the grille.
- Avoid liquid and intense heat during checks.
- Do not keep the volume at maximum during a prolonged test.
When to consider a professional check
If there is visible damage, an unusual smell, abnormal heat, charging problems, or persistent symptoms after a drop or liquid exposure, stop testing and contact the manufacturer or a repair service.
Summary
Distortion is easier to identify when it repeats across different sources. One file may itself be clipped or heavily processed, so compare speech, music and generated tones. Test at a moderate level and increase gradually. If the noise appears around the same frequency range, that pattern is more useful than simply turning the volume up.
