How Old Are Your Ears ? Hearing Test 

How Old Are Your Ears ? Hearing Test
In the United States, more than 15% of the population has some degree of hearing loss affecting daily communication, making it the most common sensory disorder.
Although it is widely accepted that the audible area of a man ranges between about 20 Hz and 20 kHz, it is possible for young children to hear frequencies up to 22 khz.
THIS TEST ONLY GIVES AN APPROXIMATE AGE.
For a better result, the video must be watched in HD and you need to have good internet connection otherwise youtube decrease audio quality. The quality of your headphones (it is not necessarily the most expensive the best for this test) or loudspeaker can have an impact of several thousand Hz on the result. Apple seems to block frequencies from 16khz. You may also have an equalizer that removes high frequencies. You can also try on multiple devices. You will get a better result if you have not been confronted in the last 48 hours with a loud noise. Don't listen too loud. A low sound volume is sufficient, you can increase it slightly when you approach the area where you stop hearing.
Due to youtube compression the maximum frequency of this video is 20Khz. For results up to 22 Khz you can see : www.arealme.co...
Disclaimer: This test is not intended to serve as a substitute for a medical consultation.
A hearing test must be carried out with standard calibrated equipment. Moreover as pure-tone audiometry uses both air and bone conduction audiometry. In addition, a high frequency audiometry medical examination is in the range of 8KHz-16Khz, in our case we go beyond that.
People with hearing loss may have difficulty hearing certain frequencies. This attenuation is measured in DB (decibel) and must be measured with standardized equipment from a professional. Hearing loss can be temporary or irreversible.
Several factors can impact high frequency audiometry, exposure to noise, certain medications (ototoxic), infection (in children and young adults, generally reversible within 1 month, but can persist if recurrent infections of the ear) or simply earwax which obstructs the ear canal (the most common cause in the elderly)... but there is also a loss of sensitivity with age.
In this test we use the formula: age = 110 - frequency / 200 which gives an APPROXIMATE AGE
In the publication « Extended high-frequency audiometry in healthy adults with different age groups », they studied 162 people aged 21 to 70.
Subjects under 30 years old were totally responsive up to 16 kHz, and 52.2% could respond to 20 kHz. No responsiveness was recorded to 20 kHz in the 51 ~ 60 group and even to 18 kHz in the 61 ~ 70 group. And no apparent impact on verbal communication was observed due to high frequency hearing loss.
Human communication frequencies are 75 to 140 hertz (Hz) for men, 170 to 250 Hz for women, and 300 to 450 Hz for children. This test does not cover these frequencies.
It's the upper frequencies we lose first with age. So let's test at which frequency do you stop hearing sound.
