Hearing Age Test & Ear Age Calculator
Discover your true biological hearing age by testing the highest audio frequencies your ears can perceive (8 kHz – 20 kHz). Test the famous 17.4 kHz mosquito tone and download your hearing certificate.
Calibrate Your Listening Volume
Click the button below to play a standard 1,000 Hz reference tone. Adjust your device or headphone volume until this tone is clearly audible, comfortable, and not unpleasantly loud.
Your upper hearing cutoff is 16,000 Hz. You retain excellent high-frequency auditory perception, placing your ears in the top 25% of adults.

The Science of High-Frequency Hearing & Ear Age
Why high-pitched sounds vanish first as we get older, how the cochlea processes audio frequencies, and the physics of the 17.4 kHz mosquito ringtone.
What is Presbycusis?
Presbycusis is the gradual, natural loss of hearing that occurs in most individuals as they grow older. It typically affects both ears equally and begins with the highest frequencies long before speech comprehension is noticeably impaired.
Because human conversational speech primarily occupies the 500 Hz to 4,000 Hz spectrum (often referred to as the "speech banana"), an individual can easily lose the ability to detect 14,000 Hz or 16,000 Hz without realizing they have experienced any functional hearing decline in daily social situations.
The 17.4 kHz "Mosquito Tone" Phenomenon
In 2005, a Welsh security inventor developed the "Mosquito" device: an acoustic deterrent that emitted an ultra-high 17.4 kHz tone to discourage teenagers from loitering outside storefronts. Because stereocilia hair cells sensitive to 17 kHz deteriorate naturally by the early 20s, adults could walk by without hearing a sound, while teenagers found the high-pitched buzzing unbearable.
Students soon adopted the sound as the "Teen Buzz" ringtone, allowing them to receive text messages and alerts on their mobile phones in class without their teachers ever noticing!
Frequency vs. Biological Hearing Age Norms
Clinical psychoacoustic studies show a direct correlation between age cohorts and upper audible frequency limits:
| Highest Audible Frequency | Estimated Hearing Age | Real-World Perception & Common Sounds |
|---|---|---|
| 19,000 Hz – 20,000 Hz | Under 18 Years Old | Near the theoretical limit of human hearing. Pristine, undamaged basilar membrane. |
| 17,000 Hz – 18,000 Hz | Under 24 Years Old | The famous 17.4 kHz "Mosquito Tone" threshold. Audible to most high school and college students. |
| 15,000 Hz – 16,000 Hz | Under 30 Years Old | Typical young adult threshold. Subtle high-end roll-off from lifestyle headphone use. |
| 14,000 Hz | Under 40 Years Old | Earliest onset of standard adult presbycusis. High-pitched cicadas begin to sound faint. |
| 12,000 Hz | Under 50 Years Old | Mid-life average. Old CRT television flyback transformer whine (15.7 kHz) is completely inaudible. |
| 10,000 Hz | Under 60 Years Old | Mature adult threshold. Upper overtones of cymbals and flute harmonics are muted. |
| 8,000 Hz or Below | 65+ Years Old | Standard senior threshold. Conversational vowels and low consonants remain fully intelligible. |
Soundcards, DACs, and Nyquist Limits
To generate an analog tone of 20,000 Hz, your digital audio converter (DAC) must operate at a minimum sample rate of 40,000 Hz (the Nyquist theorem). Virtually all modern smartphones and computers operate at 44.1 kHz or 48 kHz, meaning your computer hardware is physically capable of producing these tones.
However, cheap plastic smartphone speakers and laptop micro-drivers often introduce low-pass acoustic damping above 14 kHz. If you are struggling to hear high frequencies, plug in wired earbuds or over-ear studio headphones for the truest representation of your hearing!
