Frequently Asked Questions
Common questions about headphone testing
Why can't I hear any sound?
Possible reasons include: 1) Headphones not properly connected; 2) System volume muted or too low; 3) Wrong audio output device selected in system settings. Check your connections and audio settings.
Why is one channel louder than the other?
This usually indicates a wiring issue or driver imbalance. Try: 1) Check the headphone cable connection; 2) Clean the audio jack; 3) Test with different audio source; 4) Use the balance control to compensate temporarily.
Why can't I hear certain frequencies?
The frequency sweep test plays tones from 20Hz to 20kHz. If you can't hear certain frequencies: 1) Low frequencies (20-100Hz) require headphones with good bass response; 2) High frequencies (15kHz+) may be inaudible due to age-related hearing loss; 3) Some budget headphones have limited frequency range.
How can I get accurate test results?
For accurate testing: 1) Use a quiet environment; 2) Start with low volume and increase gradually; 3) Test each channel separately first; 4) Compare results with known good headphones; 5) Run multiple tests for consistency.
Is it safe to test at high volumes?
Yes! High volume levels can cause permanent hearing damage. Always: 1) Start with low volume; 2) Take breaks during extended testing; 3) Avoid prolonged exposure to high frequencies; 4) If you experience discomfort, stop immediately.
What does the oscilloscope display show?
The oscilloscope shows real-time audio waveforms. A clean sine wave indicates pure tone playback. Distorted or clipped waveforms may indicate: 1) Volume too high; 2) Driver distortion; 3) Poor quality audio source. Use it to visually verify audio quality.
