About This Test

What is a Hearing Age Test?

A Hearing Age Test is a digital audiometric assessment that measures the upper frequency limit of the human ear, typically ranging from 8,000 Hz to 22,000 Hz. It is used to detect early signs of Presbycusis (age-related hearing loss).

3 Signs of High-Frequency Hearing Loss

  • Difficulty understanding speech in noisy environments (Cocktail Party Effect).
  • Inability to hear high-pitched sounds like birds chirping or phone notifications.
  • Frequent need to ask others to repeat themselves, especially women and children.

How This Test Works

This online tool generates a pure sine wave that sweeps from 22,000 Hz down to 8,000 Hz. By pausing the generator the moment you can hear the sound, we can estimate the physiological age of your cochlea based on ISO 7029 standards.

Key Concepts

Presbycusis
The cumulative effect of aging on hearing, characterized by the progressive loss of high-frequency sensitivity due to hair cell degradation in the cochlea.
Hertz (Hz)
The unit of frequency in the International System of Units (SI), equal to one cycle per second. Humans typically hear between 20 Hz and 20,000 Hz.
Stereocilia
Microscopic hair-like projections on the hair cells within the inner ear that transform mechanical sound vibrations into electrical nerve impulses.

Common Questions

Is this online hearing test accurate?
This is not a calibrated hearing screen. Hardware, headphone response, browser audio and comfortable volume all affect the result. If you have hearing concerns, seek a professional evaluation.
Why can't I hear 18,000 Hz?
High-frequency audibility varies among people and playback devices. An inaudible browser tone could be due to headphones, volume or hearing, and cannot by itself establish hearing age.
What is the Mosquito Tone?
The 'Mosquito Tone' is a sound at 17.4 kHz. It is famously used as a ringtone by teenagers because most adults over 25 cannot hear it.
