How to use Speaker Test
- Set your volume to a comfortable level and play the Mid tone first.
- Play Bass and Treble and listen for rattling, buzzing or crackling.
- Run the full sweep to hear the whole range and notice where the sound drops away.
What the test tones tell you
Each button plays a pure tone at one frequency. Bass at 60 Hz shows whether your speaker or subwoofer can reproduce deep sound; small phone and laptop speakers often play it very quietly. Mid at 1 kHz is where voices sit, and it should always sound clean.
The sweep glides from 20 Hz to 20 kHz in 12 seconds. A rattle at one point usually means something loose in the speaker or casing. Silence at the very top is normal, because many speakers and most adult ears stop somewhere around 15 to 17 kHz.
Frequently asked questions
Why can't I hear the bass tone?
Small speakers in phones and laptops can't move enough air for 60 Hz. Try headphones or an external speaker to confirm the tone is playing.
What does distortion sound like?
A buzzing, crackling or rattling edge on top of the clean tone. If it only appears at high volume, the speaker is being pushed past its limit.
Can high tones damage my hearing?
Keep the volume moderate, especially with headphones. High tones can seem quiet even when they are loud, so turn the volume up slowly.
