How do I test if my speakers are working?

Click the 'Start Audio' button to initialize the audio system, then use the stereo test buttons to play sound through Left, Right, or Both channels. If you hear sound from the correct speaker, your audio is working properly.

What frequencies can humans hear?

The human hearing range is typically 20Hz to 20,000Hz (20kHz). Low frequencies (20-250Hz) are bass sounds, mid frequencies (250-4000Hz) cover most speech and music, and high frequencies (4000-20000Hz) are treble sounds.

How do I test my subwoofer?

Use the Bass Test section or the frequency presets in the 20Hz-100Hz range. A working subwoofer should produce deep, rumbling bass tones. Note that laptop speakers typically cannot reproduce frequencies below 100Hz.

Why can't I hear high frequencies?

High frequency hearing naturally decreases with age. Most adults over 25 have reduced sensitivity above 15kHz. Additionally, some speakers and headphones may not reproduce frequencies above 16kHz accurately.
