From “is it working?” to a clearer answer.
- Choose your check. Start with speakers for output, or the microphone test for input.
- Keep the volume low. Select your device in system sound settings. Sound plays only after a click or tap.
- Listen, compare, troubleshoot. Read the channel labels and use each tool’s guidance. These tools provide practical checks, not calibrated measurements.

A few things worth knowing.
How do I test my sound online?
Turn your device volume down and press Start sound test. You will hear a short left tone and then a right tone. Open the speaker test for individual channels, or the microphone test to check your input.
Do I need to download an app or audio files?
No. Playback tests synthesize their tones with the Web Audio API after you press Play. There are no bundled MP3 or WAV test tracks, accounts, or installation steps.
Why is there no sound?
Check the selected output, mute switch, system volume, cable, and Bluetooth connection. Sound starts only after a click or tap. If the browser cannot start audio, the tool shows an error and lets you retry.
Can this tell me my exact volume in decibels?
No. The level control changes digital signal amplitude, not a calibrated sound pressure level. Actual loudness depends on your hardware, system volume, listening distance, and environment.
