Can You Hear the Bass?
This test plays tones from 20 Hz to 250 Hz using the Web Audio API OscillatorNode to measure your speaker or headphone low-frequency response. Sub-bass (20-60 Hz) requires a subwoofer or large-driver headphones. Most laptop speakers cut off around 80-100 Hz. Use preset buttons or the frequency slider to find your hardware's bass limit. All tones are generated locally — zero server requests.
Plays tones from 20 Hz to 250 Hz to determine the lowest frequency your speakers or headphones can reproduce.
Most laptop speakers cannot reproduce frequencies below 80 Hz; sub-bass (20-60 Hz) requires a subwoofer or over-ear headphones.

What Do Your Results Mean?
| Result | Range | Meaning |
|---|---|---|
| Good | Audible down to 40-60 Hz | Your speakers or headphones have strong bass response. Over-ear headphones and bookshelf speakers typically reach this range. |
| Warning | Audible down to 80-120 Hz only | Limited bass response typical of laptop speakers or small Bluetooth speakers. Bass-heavy audio will sound thin. Consider external speakers or headphones. |
| Bad | Nothing audible below 150 Hz | Your speaker drivers are too small to reproduce bass frequencies. This is a hardware limitation. Use headphones or external speakers with larger drivers for bass content. |
Common Issues and How to Fix Them
Cannot hear any bass tones below 100 Hz
This is normal for laptop and small speakers. Their drivers physically cannot move enough air at low frequencies. Test with over-ear headphones to confirm your hearing is fine.
Bass tones sound rattling or buzzing
Low frequencies at high volume cause physical vibrations. Lower the volume. If rattling persists at moderate volume, check for loose speaker grilles, desk items, or phone cases vibrating near the speaker.
Volume drops noticeably at certain bass frequencies
Room acoustics create standing waves that cancel sound at specific frequencies and positions. Move to a different spot in the room or test with headphones to eliminate room effects.
