Hearing frequency test.
Explore the 20 Hz to 20,000 Hz audio spectrum on your headphones or speakers. Log where bass becomes audible and where high treble rolls off, or spot-check individual benchmark frequencies.
Start low. Your system volume also affects loudness.
Tap 1 kHz Mid first to set a comfortable baseline volume before running the full sweep.
Ready. No sound plays until you choose a test.
High-frequency limits depend on both your headphones/speakers and your ears. Do not raise volume to chase inaudible tones.
How the logarithmic 20 Hz to 20,000 Hz sweep works
Human pitch perception is logarithmic: the musical distance from 20 Hz to 40 Hz (one octave) feels the same as the distance from 10,000 Hz to 20,000 Hz. A linear sweep rushes through the entire bass and midrange in a fraction of a second. This tool uses a true exponential sweep across all ten octaves so bass, midrange, presence, and upper air each receive balanced listening time.
Logging your lowest bass and highest treble limits
Start the 15-second full-spectrum sweep and watch the live frequency tracker. As soon as you hear the low rumble emerge, click Mark lowest audible bass. Continue listening as the pitch climbs; right when the high whistle disappears, click Mark highest audible treble. The tool calculates your logged frequency span in both Hertz and octaves for your current headphone or speaker setup.
Separating equipment limits from personal hearing range
Standard laptop speakers rarely reproduce bass below 80 Hz, and many Bluetooth codecs or wireless earbuds filter or roll off treble above 15,000 Hz to 16,500 Hz. If the sweep cuts out early, test again with wired headphones or use the online tone generator to spot-check individual frequencies at a steady level.
Why you should calibrate volume at 1,000 Hz first
Our ears are most sensitive between 1,000 Hz and 4,000 Hz and much less sensitive at 20 Hz and 18,000 Hz. Setting your volume while playing a 30 Hz or 17,000 Hz tone can trick you into turning the amplifier dangerously high, making the midrange painfully loud. Always set a safe baseline using the 1 kHz spot-check chip and leave the volume untouched during the sweep.
Choose your next sound check
- Headphone test — Check each ear, compare the center image, and listen for rattles or dropouts.
- Online tone generator — Generate sine, square, sawtooth, and triangle waves with fine Hz and musical note control.
- Tinnitus frequency finder — Match your ear-ringing pitch, check adjacent octaves, and preview notched masking noise.
For missing or unexpected output, follow the no-sound troubleshooting checklist. For multichannel routing, read the 5.1 surround setup guide.
Good questions.
Clear answers.
Can most adults hear all the way to 20,000 Hz?
The 20 Hz to 20,000 Hz textbook range represents young ears under ideal laboratory conditions. For most adults, the upper audible ceiling naturally settles between 13,000 Hz and 17,000 Hz.
Why do I hear a faint lower tone descending when the sweep passes 16 kHz?
If playback gain is too high or your operating system resamples audio poorly, digital aliasing or harmonic distortion can create phantom lower tones. Lower the test volume to 10–12% and retry.
Is this sweep a clinical hearing test?
No. Because consumer headphones, speakers, and room acoustics are uncalibrated, this sweep checks your combined playback chain and personal perception rather than producing a medical audiogram.
How can I test only my subwoofer bass range?
Use our dedicated subwoofer bass test, which focuses specifically on 16 Hz to 200 Hz with 1/3-octave pads and a slow room-mode sweep.
