How it works and what the result means
Stereo panning generates directional cues and the result reports correct answers. This is not a binaural HRTF or physical surround calibration.
Reading the result
Correct answers measure recognition of simple panned cues. Center uses both channels and should not be confused with a physical front speaker.
What to check next
Disable mono output and inspect accessibility balance if every cue sounds centered. A reversed headset can swap perceived left and right.
Use headphones with normal stereo routing. Mono output and accessibility balance settings can remove directional information.
Frequently asked questions
Is this a 3D surround or HRTF calibration?
No. The cues use stereo panning. They do not model a room, head-related transfer function, distance or front-versus-back placement.
How do I start the Sound Localization Test?
Start the sound cue, then select left, center or right. Each answer produces the next quiet cue.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
