How do I run a left/right speaker test online?

Press Left or Right to isolate each channel, then compare loudness and tone. Use the balance slider for fine adjustments.

Can I test my laptop or phone speakers?

Yes — this runs in your browser on iPhone, Android, Windows, and macOS. No app and nothing is recorded.

What is a 20 Hz to 20 kHz sweep?

A sweep plays tones from low bass to high treble to reveal rattles, buzz, or dropouts across the range.

Should I use pink noise or white noise?

Pink noise leans lower and is good for rattles. White noise is brighter and useful for general checks.

Speaker Sound Test Fast, private, on-device — nothing is recorded.

Quick start

1 Set a safe volume

Start low. Raise slowly. If it’s uncomfortable, it’s too loud.

2 Isolate a speaker

Use Left/Right first — it’s the fastest way to spot a dead channel.

3 Confirm with a sweep

Sweeps expose rattles and dropouts you won’t hear with one tone.

Troubleshooting & next steps

Quick FAQs

Nothing plays? Check Silent mode, Bluetooth output, and device volume.
Only one side works? Use Left/Right. If one side is always silent, it’s likely hardware.
Crackle at low volume? Moisture/debris is common — give it drying time, then retest.
Noise sounds hissy? Some hiss at high volume is normal; compare both channels.

Safe cleaning checklist

Power off the phone first.
Use a soft, dry brush — no liquids.
Avoid compressed air into the grille (it can push debris in deeper).
Re-test at 200 Hz, 1 kHz, and 10–14 kHz.

Device notes

iPhone: bottom + earpiece can act as stereo; test both.
Android: some models boost bass; check 60–200 Hz for rattles.
Laptops: try 400–5k Hz; listen for chassis resonances.

What to do next

After a minor splash, once the phone is safe to operate, allow drying and consider the Water Eject Tool. Skip sound testing if the device was heavily soaked or behaves abnormally.
Play the same test at a comfortable level and compare Left versus Right. The speaker tool does not record audio.
If one side stays silent, consider a professional repair estimate.

Water Eject Tool

Short sound cycles to help move trapped droplets.

Understand your speaker-test result

For a useful comparison, play the same sample at a comfortable volume in the same room. Disconnect Bluetooth or AirPlay first. A browser sound test helps you hear symptoms; it does not confirm that your phone is dry or diagnose internal damage.

What you hear	What to check next
No sound	Check media volume, audio output routing and another app.
Calls muffled, videos clear	Compare the earpiece versus speakerphone and inspect a dry receiver grille.
Left and right sound different	Check balance settings. Phone stereo speakers are not always the same size or loudness.
Buzzing at several levels	Lower volume, remove the case and check a dry grille for debris; persistent faults may need service.
