Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Audibility depends on the listener, output device and volume. Do not use this as a medical hearing test.
If something seems wrong
Reduce volume if distorted. Inaudible frequencies do not establish a hardware defect.

No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
