Very high tones like this are usually the first to fade as ears age, so hearing them is a good sign for your high-frequency hearing.","sub2":"You heard up to {f}. This range is still above most of what matters for speech, but the very top of human hearing is no longer audible on this setup.","sub3":"You heard up to {f}. High-frequency hearing gradually narrows with age and noise exposure; speech mostly relies on lower pitches.","sub4":"You heard up to {f}. Check the volume and headphones first; if the result stays low on good headphones, a standard hearing test at an audiologist is a sensible next step.","subNone":"You did not hear the 8 kHz tone. Check that sound is working and the volume is not too low, then try again. If you still hear nothing at 8 kHz, consider a hearing test with an audiologist or ENT doctor.","topNote":"You heard the highest tone this device can play ({f}), so your real limit may be higher.","catchNote":"You also answered \"I hear it\" to a silent trial, so treat this result with caution and try again.","speakerNote":"Many phone speakers, laptops and Bluetooth headphones cannot play tones above about 16 kHz, so a low result can be the device, not your ears.","statHigh":"Highest tone heard","statMiss":"First tone missed","statCatch":"Silent check","catchOk":"Passed","catchFail":"Answered “heard”","help":"The tones play at the same digital level. Your headphones and your volume setting change how loud they really are, and many devices drop off above 16 kHz. Tones fade in slowly so that no click gives them away. Do not raise the volume to hear the high tones: loud high-pitched sound is unpleasant and can be harmful."}},"links":{"color-blind-test":{"url":"/color-blind-test/","name":"Color Blind
