Frequently asked questions
Is this a medical test?
No. Results depend heavily on your speakers, headphones and volume, so this is for curiosity only, not a substitute for a real audiogram.
Why can't I hear high frequencies?
Most people lose sensitivity above 15–17 kHz with age, and many speakers cannot reproduce the highest tones at all.
