Bass Test

Bass is where small speakers give up first. Step through low tones or sweep the range to hear where the sound gets quiet, distorts or disappears.

Lower your volume before starting, especially with headphones. Nothing plays until you press a button.

60 Hz

Most laptop and phone speakers produce very little below 100 Hz. Keep the volume moderate: deep tones stress small speakers.

How to use

  1. Start with the volume low. Deep tones can be much louder than they seem and can damage small speakers.
  2. Pick a preset or drag the slider, then press Play.
  3. Move down the range and note the lowest tone you can clearly hear from the speaker, not just feel or hear as a buzz.
  4. Use Sweep to hear the whole range rise from 20 Hz to 250 Hz.

What this test can detect

  • The lowest frequency your speakers can reproduce.
  • Rattles and buzzing from loose parts or resonating objects near the speaker.
  • A subwoofer that is off, disconnected or crossed over too high.
  • Port noise or distortion at high levels.

Important

  • Most laptop and phone speakers produce almost nothing below 100 Hz. That is a design limit, not a fault.
  • Room acoustics create peaks and dips in bass. Move your head or the speaker and the loudness will change.
  • Keep the volume moderate. Sustained loud low tones stress speakers and hearing alike.
