How to Interpret Your Speaker Test Results
Rattling or Buzzing on Low Frequencies (100 Hz – 250 Hz)
If the speaker makes a buzzing or fluttering sound at 100–250 Hz, trapped water droplets are almost certainly vibrating against the cone or mesh. Run the Clean My Speaker water eject tone again.
Hissing or Dullness on Treble (5 kHz – 10 kHz)
If high frequencies sound faint, dead, or muffled, the acoustic pores are likely blocked by fine lint, pocket dust, or dried debris. Use a dry, soft-bristled brush to gently clear the exterior holes.
Uneven Stereo Channel Volume
If the Left or Right channel is noticeably quieter, check your operating system accessibility settings (Audio Balance slider) or inspect the quieter speaker opening for physical blockage.
Complete Silence
Ensure device volume is turned up and silent switches are off. If no sound plays across all frequencies, your browser may be blocking audio or the speaker coil may have failed.
