Speaker Test

Check left and right speaker or headphone channels with short stereo tones. Record what you hear, compare two tests and print a local report. No download.

Check left, right and stereo sound

Use speakers or wear your headphones the right way round. Lower your system volume before starting. Each button plays a short tone; the test does not listen through a microphone.

Digital signal level only; your device volume is separate. 0% is silent. Stop if the sound is uncomfortable. Changing the level clears this test’s observations.

Play each tone, then select where you heard it. Start with low system volume.

1. Left channel

Expected: Left only

Where did you hear the left tone?

Play the full two-second tone to enable these choices.

2. Right channel

Expected: Right only

Where did you hear the right tone?

Play the full two-second tone to enable these choices.

3. Stereo channel

Expected: Both sides

Where did you hear the stereo tone?

Play the full two-second tone to enable these choices.

The browser sends stereo signals, but mono settings, Bluetooth devices and sound processing can mix or change them. Your selections describe what you heard, not a hardware diagnosis or a hearing test. Repeat under the same settings to compare observations.

Check a used headset, confirm channel routing or compare listening observations before and after a change. This test generates sound in your browser and does not request a microphone or record audio.

A repeatable left and right speaker check

Lower your system volume first. Play each two-second 440 Hz tone and select Left, Right, Both, No sound or Unsure. The expected output is left only, right only and both sides respectively. The browser cannot verify what your speakers actually reproduce; the report contains your selections.

If a single-channel tone is heard on both sides, check mono audio, spatial sound, soundbar modes and other system processing. A Bluetooth device may mix stereo into a single speaker. These observations do not prove a broken speaker or headphone driver. No hearing threshold, sound pressure, hardware latency or frequency response is measured.

Keep the same system volume, digital signal level, output device and listening position when comparing tests. Changing the signal level clears the current observations. Test settings and reports stay in this page session; print a report before reloading or leaving.

Frequently asked questions

How do I test left and right speakers?
Play the left tone and check where you hear it, then repeat for right and stereo. Lower your system volume before starting and use Stop sound or Escape to stop immediately.
Why do I hear a left or right tone on both sides?
Mono settings, a single-driver speaker, Bluetooth hardware or system sound processing can mix channels. Check those settings before drawing conclusions about hardware.
Does this test diagnose faulty hardware or hearing?
No. It plays test signals and records your listening observations. It does not measure your physical output, hearing, latency or calibrated loudness.
Is my sound or report uploaded?
No microphone or recording is used. Test settings and observations remain in this page session. Analytics receives only the tool ID and action type.
