How It Works

  • • Plays pure tones through your headphones (one ear at a time) at key frequencies from 250Hz to 8kHz.
  • • You adjust the level until you just barely hear the tone. We record the relative threshold setting (0–100) for each frequency.
  • • The results are best used to compare left vs right and low vs high frequencies under the same setup.
  • • For a detailed explanation of how to interpret your results, read our comprehensive guide to hearing self-checks.

Important Limitations

  • Your results are not calibrated clinical units (not dB HL). They depend on device volume, headphones, EQ, and room noise.
  • This tool cannot diagnose hearing loss or medical conditions. Use it as a trend and comparison, not a diagnosis.
  • For best accuracy, measure in a quiet room (you can check background noise with our Online Decibel Meter).

At-Home Checklist (Best Results)

Before You Start

  • Use headphones (over-ear preferred). Speakers are not recommended.
  • Find a quiet space. Background noise can mask the softest tones.
  • Set your volume low first, then use the volume check step.
  • Test one ear at a time. Remove the other earcup if possible.
  • Repeat the test if you were distracted or the room was noisy.

Safety and When to Seek Help

  • Stop immediately if any tone feels uncomfortably loud.
  • If you have sudden hearing changes, ear pain, or one‑sided symptoms, consult a clinician promptly.
  • If you repeatedly notice a large left/right difference or a sudden change over time, consider a professional hearing evaluation.
  • This tool is a screening aid and cannot diagnose medical conditions.

How This Online Hearing Test Works

Volume Calibration

1. Calibrate

Set your device volume to a comfortable level using the reference sound, then keep it unchanged for the rest of the test.

Hearing Test Frequencies

2. Test Frequencies

We test 6 key frequencies (250Hz–8kHz) for each ear and record the lowest relative level where you can just hear each tone.

Frequently Asked Questions

How often should I take this test?

Use it when you want a repeatable screening. For tracking, keep the same headphones, device, and quiet environment. Many people repeat it every few months or after a significant change in noise exposure.

Is this test as accurate as a doctor's visit?

No. Clinical hearing tests use calibrated equipment in controlled environments. This tool is an informational screening that produces device‑dependent, relative results. If you have concerns, symptoms, or sudden changes, consult a licensed professional.

How do I read the chart?

The chart shows the lowest relative threshold setting (0–100) where you could just hear each tone. Lower values generally mean you needed less level under the same setup. Look for patterns (left vs right, low vs high frequencies) and repeat the test with the same settings if you want to track changes.

Why does the test start at 1000Hz?

1000Hz is a common reference tone that many people can recognize easily. We then test higher frequencies and finish with lower ones to keep the flow consistent and reduce fatigue.

Why can't I go back to the previous step?

To keep the test simple and repeatable, it proceeds in a fixed order. If you were distracted or think a step was wrong, retake the test in the same quiet setup.

Do you collect or store any personal data?

No. The test runs locally in your browser. We do not ask for email or signup, and your hearing results are not uploaded.

What headphones and settings should I use?

Use headphones (over‑ear preferred). Turn off EQ/enhancements if possible, and keep the same device volume for the entire test. A quiet room improves consistency.

What if a tone feels too loud or uncomfortable?

Stop immediately and lower your volume. Do not keep listening to uncomfortable tones. If you have ear pain, sudden symptoms, or concerns, consult a clinician.
