What is the difference between a sound test and a speaker test?

The speaker test checks whether left and right channels work. The sound test focuses on frequency response — whether your setup can reproduce specific tones from deep bass to high treble.

Why can I not hear the very low or very high tones?

Small laptop speakers often cannot reproduce frequencies below 100 Hz. High-frequency hearing declines naturally with age — most adults cannot hear above 15–17 kHz.

Is this test safe for my speakers?

Yes. The tones are generated at controlled levels. Keep the volume moderate, especially when testing bass with headphones.

How To Use It

Set the volume to a comfortable level using the slider.
Pick a frequency preset or play the bass test to check low-end response.
Run the full sweep to hear the range from 20 Hz to 20 kHz.

Troubleshooting

If you cannot hear tones below 100 Hz, your speakers may lack bass capability — try headphones.
The upper hearing limit decreases with age; not hearing above 15 kHz in the sweep is normal for adults.
Use moderate volume to protect your hearing, especially with headphones.
