Prepare Quietly
Choose a quiet setting, use headphones only at low comfortable volume, and read the non-diagnostic notice.

Before you begin
Choose a quiet place. If using headphones, set device volume low. This uncalibrated browser check cannot diagnose hearing loss.
ReadyChoose Start Check
Only report what you notice at the current fixed setting. Do not raise device volume to force a response.
Session observations
These are your responses from an uncalibrated browser session, not a clinical result. Hardware, level, processing, surroundings, and attention all affect them.

Online Hearing Test & Hearing Range Check
Make a simple, low-level record of which browser-generated frequencies you report hearing in this session, without clinical scoring or diagnostic claims.
What This Online Hearing Test Can and Cannot Do
This online hearing test is a browser-based hearing range check. It presents brief sine signals and records whether you choose “I Hear It” or “I Don’t Hear It.” Quick mode steps from 125 Hz through selected high frequencies; manual mode checks one chosen value. You can route the requested signal left, right, or to both channels. The result is only a summary of your responses at the current device, volume, environment, and moment.
This page is not an audiogram, does not measure dB hearing level, and cannot classify hearing as normal, mild, moderate, severe, or otherwise. It does not estimate hearing age or diagnose disease. Clinical threshold testing requires calibrated transducers, controlled presentation levels, suitable surroundings, and professional interpretation. The phrase online hearing test describes the search task, while the product itself is repeatedly limited to an uncalibrated frequency-range check.
Three simple steps
How to Get Started
Use this online hearing test deliberately: set the signal, begin quietly, and interpret only what the workflow can actually show.
Choose Mode and Channel
Run the guided range sequence or one manual frequency through left, right, or both outputs.
Report, Do Not Chase
Answer at the fixed low setting, replay if needed, and never raise volume to force an inaudible tone.
How the Browser Hearing Range Check Works
After explicit acknowledgment, Quick mode begins at 125 Hz and progresses through 250 Hz, 500 Hz, 1, 2, 4, 8, 10, 12, 14, 16, 18, and 20 kHz. Each signal lasts about one second at a fixed 8 percent browser gain with short fade edges. The next frequency plays only after a response. Manual Frequency Check uses the same envelope and level for one selected value. Stop remains available throughout the active workflow.
Why Headphones and Device Hardware Matter
Headphones and speakers have uneven frequency response and may roll off well before the nominal limits shown on a specification sheet. Laptop and phone speakers are especially limited at low frequencies, while many playback paths attenuate extreme treble. Wireless codecs, equalization, volume limiting, spatial processing, and sample-rate conversion may change output further. Failing to notice a signal can therefore reflect the hardware or settings rather than the listener.
Understanding Frequency vs Hearing Threshold
Frequency describes cycles per second and relates to pitch. Hearing threshold describes the minimum sound level detected under defined conditions at a frequency. This online hearing test varies frequency but does not measure the acoustic level at your ear, so it cannot find a clinical threshold. A browser gain percentage is not dB SPL or dB HL. Keeping one conservative digital setting avoids the unsafe pattern of making high-frequency signals progressively louder until something is perceived.
Left and Right Ear Checks
Channel selection changes stereo pan, which is useful for noting whether your response differs between the left and right playback paths. It does not guarantee acoustic isolation: headphone fit, wiring, device accessibility features, mono output settings, and crosstalk may route sound differently. Label any comparison as a user-reported session observation. Do not infer the location or cause of a difference from this page alone, and confirm that the headset is oriented correctly before comparing sides.
What Your Results Mean - and Do Not Mean
The summary counts reported-heard signals and lists the highest reported frequency in that run when one exists. It does not say that every lower frequency was audible, assign a score, or label the result normal or abnormal. Attention, fatigue, background sound, expectation, and accidental sounds can change responses. Repeating the range check may produce a different pattern. Treat the record as a note about one browser session, not a durable fact about hearing ability.
How a Professional Hearing Test Is Different
A qualified hearing professional can use calibrated equipment, controlled procedures, multiple signal levels, masking when appropriate, bone and air conduction methods, and an examination relevant to the person’s concern. Those elements help distinguish threshold, equipment, ear, and pathway factors that a web page cannot separate. If you have a hearing concern, persistent asymmetry, or difficulty understanding speech, seeking a qualified professional is a reasonable next step without treating this range check as a diagnosis.
Safe Listening
Set system volume low before beginning and keep the site-controlled output fixed. Stop immediately if any signal is uncomfortable. Do not repeat extreme frequencies for long periods, press headphones tightly against the ears, or increase volume because 18 or 20 kHz is not noticed. Many adults and many devices do not reproduce or perceive the top of the displayed range reliably. The obvious Stop button fades the oscillator and ends the session sound immediately.

Frequently Asked Questions
Is this online hearing test diagnostic?
No. It is an uncalibrated browser hearing range check and cannot diagnose hearing loss or replace a professional evaluation.
Why can I not hear 18 or 20 kHz?
The playback hardware, signal path, device settings, environment, and hearing can all limit very high-frequency perception. This page cannot identify which factor is responsible.
Does the result calculate hearing age?
No. Hearing-age labels are not produced because a browser frequency check does not support that conclusion.
Should I increase volume until I hear a tone?
No. Keep volume low and stable. Raising level to force detection can be uncomfortable or unsafe and would not create a calibrated threshold.
