Depth resolution: the scientific rationale and significance of online hearing tests

Hearing is the key window for human perception of the world. As age increases and environmental noise affects, our hearing range will gradually shrink, especially with regard to the perception of high frequency voices. Use of this tool Web Audio API produces pure swire waves, simulates the testing process of a professional hearing counter, and helps you to complete the basic hearing assessment at home.

1. What is the frequency response test?

The ideal hearing range for humans is 20 Hz to 20,000 Hz. Tests are played by different frequencies:

  • Low frequency (250Hz-500Hz): Corresponds to background and parts of the environment.
  • Medium frequency (1,000 Hz - 4000 Hz): The critical frequency of language understanding is within which most of the voices are exchanged.
  • HF (above 8,000 Hz): Details of music, birds' sounds and frequency are also the most susceptible to degradation with age.

What is the “heart age”?

Medical studies have shown that the hair cells responsible for sensory high frequency are most vulnerable to damage in the inner ear. Usually:

  • Under 20: Can hear 17,000 Hz - 19,000 Hz.
  • 30-40 years: Can hear 14,000 Hz - 15,000 Hz.
  • Over 50 years of age: It is usually difficult to hear more than 12,000 Hz.

How can your hearing be protected?

If you find the test results significantly lower than those of your peers, the following “60-60 principles” are recommended:

  1. Volume control: When using headphones, the volume should not exceed 60% of the maximum volume.
  2. Length limit: The continuous use of headphones should not exceed 60 minutes.
  3. Physical protection: (b) The wearing of noiseproof ear plugs in high noise environments (e.g. construction site, music festival).

Legal exoneration: This test is not a medical diagnosis. The result is influenced by the quality of the equipment (headphones, sound cards), environmental noise and volume settings. If there is a severe sound or a sudden loss of hearing, you must immediately seek medical attention.
