Terms
listen responsibly
Audio Tests Online provides free educational audio tests. By using the tools you agree to use them at safe volumes and to treat every result as informational.
Not a medical device
Hearing content on this site is screening and education only — never diagnosis, treatment, or medical advice. Nothing here replaces a qualified audiologist or hearing professional.
Levels are relative, not absolute
All readouts are in dBFS, relative to full scale — not SPL. Browser playback is uncalibrated, so a reading here cannot tell you how loud a sound is in your room or whether it is safe. Start quiet, never raise the volume to chase a faint tone, and stop immediately if anything hurts.
Your responsibility
You are responsible for your volume knob. High frequencies, sub-bass, and noise at high gain can damage hearing and equipment. Every tone starts from your gesture, and Stop and Mute are always available — use them.
Content and availability
Tools are provided as-is, without warranty. Pages, frequencies, and presets may change as the site improves. Be kind: do not abuse, scrape aggressively, or misrepresent results as certified measurements.
