Speaker and earpiece check
This phone speaker test has four short parts. Each part plays a sound or a vibration. You tell us what you hear or feel. Nothing is recorded.
- Set the volume to a medium level.
- Disconnect Bluetooth headphones and speakers.
- Keep the phone away from your ear. Do not hold the earpiece against your ear.
A web page cannot choose between the earpiece and the loudspeaker. The browser and the phone decide. To check the earpiece, make a normal call at low volume.
Test 1 of 4
1. Rising sweep
A sound rises from low to high pitch (200 to 4000 Hz). It lasts about 4 seconds.

Test 2 of 4
2. Left and right channel Experimental
A 440 Hz tone plays on the left channel for 1.5 seconds. Then it plays on the right channel for 1.5 seconds.
Phones decide which physical speaker plays each channel. Many phones have one speaker, so both tones can sound the same. Hold the phone in landscape. The result is a hint only.

Test 3 of 4
3. Low and high tone
A low tone (100 Hz) plays for 1.5 seconds. Then a high tone (2000 Hz) plays for 1.5 seconds. Compare them.
Small phone speakers play 100 Hz quietly. A quiet low tone is normal.

4. Vibration
The phone vibrates in a pattern: long, short pause, long.
Vibration works in Chrome and Samsung Internet on Android. Some phones ignore it in silent mode.

Next steps
How to run a phone speaker test
Run the four parts above in order. Each part is a simple audio test of a different thing. This online tool runs in your browser. It is a basic sound test, not a lab measurement. It cannot give measured numbers. Compare the result with earbuds as a second check. If the audio is clear on earbuds but weak on the phone, the fault is in the phone or its grille.
What the rising sweep shows
The sweep moves from low frequency to high frequency It is a quick test of the frequency response of your phone. Frequency response is how loud a device plays each frequency. A clear sweep means the phone plays this whole frequency range. Listen for a rattle or gaps. A muffled sweep can mean that dust or water blocks the grille. Apple says water in the port might degrade speaker performance until it completely evaporates.
Stereo: what the left and right part shows
A stereo phone plays two audio channels. This part tests the left channel and then the right channel. Many phones have one speaker. That speaker plays a mono mix, so both tones are the same. The phone decides which physical speaker plays each channel. Treat the result as a hint, not as a fault.
What the low and high tones show
Bass is low frequency audio. Small phones play bass quietly. A weak low tone is normal. Our reading of micro-speaker datasheets is that resonance lies at roughly 450 to 900 Hz. A weak high tone, or weak treble, is more telling. It can point to a blocked grille.
Keep the volume safe
Keep the volume at a reasonable level. Phone speakers reach about 70 to 77 dBA at full volume (DXOMARK). Sessions are short and have pauses. Hold the phone away from your ear. Stop if you notice ringing or feel pain.
Frequently asked questions
How do I know if the speaker works?
Run the four parts above at a medium volume. If you hear clear sound in the sweep and the tones, the speaker most likely works. Run the test again after you clean the grille or after the phone dries.
What if the test produces no sound?
Look at the media volume, silent mode and Do Not Disturb. Turn off Bluetooth, because the audio can play on a headset nearby. Restart the phone and play the test again. If there is still no sound, a repair may be needed.
How can I check the call speaker?
A web page cannot choose between the earpiece and the loudspeaker. To test the earpiece, make a normal call at low volume. Keep it away from your ear while you listen.
How can I test for low volume or crackling?
Play the sweep and listen for crackle or distortion. Play it on earbuds too. General advice: crackle in every test, and on earbuds too, points to a hardware fault. A repair is then the most likely fix.
If a part sounds wrong
- Use the speaker problem finder to find the most likely cause.
- For dust, read how to clean dust from the speaker grille. Use a dry, soft brush. Do not use compressed air.
- If the phone got wet, follow the wet phone checklist.
What this speaker test can and cannot show
- They play sounds from your browser. They do not measure loudness.
- They cannot tell water from dust or a hardware fault.
- They cannot choose the earpiece or the loudspeaker. The phone decides.
- They do not record or upload anything.
