Speaker Test
Four short sounds check your left speaker, right speaker, bass and treble. Start with the volume low.

How It Works
Your browser cannot hear its own sound, so you are the judge. Each step plays one sound and asks what you heard. You can replay any sound as often as you like.
The first two steps play beeps at 440 Hz on one channel only. If they come from the wrong side, your speakers or cables are swapped; if they come from both sides, your output is probably set to mono.
Then a 60 Hz hum tests bass and a 10 kHz tone tests treble. These show a blown or rattling speaker, and one that sounds muffled.
Interpreting Your Result
A speaker you cannot hear at all is usually a loose cable, a plug in the wrong socket, or a balance setting pushed to one side. Check your system sound settings before assuming it is broken.
No bass at 60 Hz is normal on laptops, phones and small desk speakers: they are too small to play it. A buzz or rattle is different. It means something in the speaker is loose or damaged.
Everyone’s hearing of high notes fades with age, so missing the 10 kHz tone is not always the speaker. Try it with headphones: if you hear it there, the speaker is muffled.
Checking your whole audio setup? The mic test checks your microphone the same way.
Frequently Asked Questions
How do I test if my speakers are working?
Play the left and right test sounds on this page and check each comes from the correct side. If one side is silent, check its cable, the balance in your sound settings, and that the right output device is selected.
Why is sound only coming from one speaker?
Usually a loose or half-inserted cable, or a balance setting pushed to one side. If both are fine, the silent speaker may be faulty. Until it is fixed, turning on mono audio in your accessibility settings plays everything through the working side.
Why do my speakers rattle or buzz?
A rattle on low notes usually means something is loose, either inside the speaker or touching it, or the speaker cone is damaged. Lowering the volume can confirm it: damage keeps rattling at lower volume, while overload stops.
Can a speaker test damage my speakers?
Not at a normal volume. The test tones are played at a moderate level, but a low bass tone at full volume can push small speakers hard. Start with the volume low and turn it up until you can hear each sound clearly.
Does this work with headphones and Bluetooth speakers?
Yes. It plays through whatever output your computer or phone is using: built-in speakers, headphones, Bluetooth or a monitor. Select the output you want to test in your system settings first.
