Play fixed tones at a comfortable volume to notice broad listening patterns. This non-calibrated browser screening is not a diagnostic hearing test or an audiogram.
Check which pure-tone frequencies you notice from 125 Hz to 16,000 Hz. Use headphones for the most meaningful left/right comparison. This is a non-calibrated screening only, not a medical diagnostic test.
This tool plays pure sine wave tones at eight common test frequencies using the Web Audio API'sOscillatorNode,GainNode, andStereoPannerNode. Each tone plays for three seconds. Use the left/right ear selector with headphones, then mark each frequency as heard or not heard to create a non-clinical summary.
The browser cannot measure clinical hearing thresholds in dB HL or replace sound booth testing.
Frequency response, fit, volume setting, and audio enhancements all affect which tones you notice.
Keep tones comfortable and stop if anything feels painful, sharp, or unpleasant.
Sudden changes, one-sided differences, ringing, pain, or speech clarity problems deserve professional evaluation.
Very high tones are often easier to notice, depending on headphone output.
Some high-frequency rolloff is common and varies widely between people.
Very high tones may be less noticeable, especially with device or noise limitations.
Speech clarity concerns should be assessed clinically, not inferred from this page alone.
These are broad educational patterns, not diagnostic thresholds. Individual hearing varies significantly.
