Question 1

How do I test if both speakers are working?

Accepted Answer

Use the left/right channel test to play audio through each speaker independently. If you only hear sound from one side, the other speaker may be disconnected, damaged, or your audio balance setting may be off. Check your OS audio balance settings.

Question 2

How do I test bass response?

Accepted Answer

Use the tone generator and sweep through low frequencies (20-200 Hz). Good speakers and subwoofers should produce audible bass down to at least 50 Hz. If you can't hear anything below 100 Hz, your speakers may lack bass capability or your subwoofer might be disconnected.

Question 3

What frequency range should I be able to hear?

Accepted Answer

Normal human hearing ranges from 20 Hz to 20,000 Hz (20 kHz). Most people lose high-frequency hearing with age — by 25, many can't hear above 17 kHz. Use the frequency sweep to find your personal hearing limit. Speakers should reproduce at least 80 Hz to 16 kHz clearly.

Question 4

Can I test my headphones with this tool?

Accepted Answer

Yes! The speaker test works perfectly with headphones and earbuds. The left/right channel test is especially useful for verifying each earpiece. Use the frequency sweep to check for driver imbalances between left and right.

Question 5

How does the tone generator work?

Accepted Answer

The tone generator creates pure sine wave tones at any frequency you choose using the Web Audio API. Adjust the frequency slider to generate tones from 20 Hz (deep bass) to 20 kHz (ultrasonic). You can also adjust volume. This is useful for testing speaker frequency response and identifying resonance issues.

Question 6

Why can't I hear very low frequencies?

Accepted Answer

Most laptop speakers and small desktop speakers can't reproduce frequencies below 80-100 Hz. You need dedicated speakers with larger drivers or a subwoofer for deep bass. Also, at very low volumes, bass frequencies become inaudible due to the Fletcher-Munson equal-loudness contours.

Question 7

Can I test surround sound (5.1/7.1)?

Accepted Answer

Browser-based audio is typically limited to stereo output (left/right channels). For true surround sound testing, you need desktop applications that support multi-channel audio output. Our stereo test verifies your front left and right channels, which are the foundation of any surround setup.

Question 8

Is the audio test safe for my speakers?

Accepted Answer

Yes, the test generates standard audio signals at safe levels. Start with low volume and increase gradually. Avoid playing very low frequencies (< 30 Hz) at maximum volume for extended periods, as this can stress speaker drivers. The default volume level is completely safe.
