People of All ages without a hearing impairment should be able to hear the 8000hz. People under 50 should be able to hear the 12,000hz and people under 40, the 15,000hz. Under 30s should hear the 16,000hz, and the 17,000hz is receivable for those under 24.
While the upper limit for the average adult is 20,000 Hz, the highest-pitched sounds most people can hear fall between 15,000 to 17,000.
Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
People with normal hearing can hear sounds between 20 and 20,000 Hz.
The normal frequency range of a young healthy person's hearing is about 20 to 20,000 Hz. As we age, we begin to lose our hearing at the upper frequencies, bringing the range to about 20 to 14,000 Hz. Typically, people's hearing is the most sensitive in the 2000 - 5000 Hz frequency range.
Whereas a person in their twenties will be able to hear up to 17,000Hz or more, by their thirties this will have declined to about 16,000Hz. By the time an individual is in their 50s, their hearing range will usually have declined to around 12,000Hz.

The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.
The 'normal' hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a 'normal' audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it's the upper frequencies we lose first.
In addition to decibel levels, harmful sound frequencies can also be damaging to human hearing. Low frequencies (under 20 Hz) and high frequencies (above 20,000 Hz) that humans cannot perceive can also affect the ear and have adverse effects on our health.
(Hertz is a measure of the frequency of a sound, and the higher the frequency, the higher pitched the sound.) Dogs, on the other hand, can hear sounds as high as 47,000 to 65,000 Hz. These are sounds far too high-pitched for us.
For an average adult middle-aged person, 12-14 kilohertz is the highest frequency they can hear clearly. Note: Some animals, such as dogs, can hear sounds of frequencies greater than 20 KHz. In certain applications inaudible frequencies are beneficial.
A high-frequency hearing loss is a hearing loss where you are unable to hear sounds that occur in the higher end of frequencies, which are frequencies of 2,000 Hz or higher. These sounds are also called the higher sounds or high-pitched sounds.
12,000 Hz is hard for anyone over 50 years of age to hear.
The human hearing range is around 20 to 20,000 Hz, and as we get older, our ability to hear high-pitched sounds begins to decrease. Age, and other factors like exposure to noise, can have a big impact on the frequencies we hear.
It's a common problem linked to aging. One in 3 adults over age 65 has hearing loss. Because of the gradual change in hearing, some people are not aware of the change at first. Most often, it affects the ability to hear high-pitched noises such as a phone ringing or beeping of a microwave.
Getting tested
Hearing tests measure how loud a sound needs to be before you clearly hear it. People with normal hearing can identify sounds of less than 25 decibels (dB). Mild hearing loss means you require sounds to be in the 26 to 40 dB range, and moderate hearing loss, your minimum hearing in the 41 to 55 dB range.
An online hearing test is a simple, often free tool you can use to test for hearing loss. “The results from an online hearing test can indicate whether you may have hearing loss, but you'll still want to follow up with a professional,” said Amy Sarow, a practicing doctor of audiology based in Michigan.
Hearing tests are performed by an audiologist. You can do an online hearing test if you're not sure if you have hearing loss, but it's less accurate. Most hearing tests check how loud a sound needs to be for you to be able to hear it. The results are recorded on an audiogram.
Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them.
The response of the ear is governed, in part, by the mass and elasticity of the eardrum, muscles and ligaments, bones, and fluid and structures in the inner ear. Elasticity opposes low frequency sounds, while mass opposition increases as frequency increases. So both mass and elasticity set limits for frequency range.
Kids and adults had equal ability to hear the frequencies up to 5,000 Hz. After that point, 100 percent of the children heard up to 10,000 Hz, 96 percent heard up to 15,000 Hz, until only 22 percent could hear 20,000 Hz.
The lowest decibel a human can hear is 0 dB. In some exceptional cases, humans can hear sounds down to -15 dB. 0 dB sounds are very soft and barely perceivable by the human ear. To understand just how soft, imagine that a whisper is 30 dB and 30 dB is 1,000 times louder than a 0 dB sound.
On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz. While 20 to 20,000Hz forms the absolute borders of the human hearing range, our hearing is most sensitive in the 2000 - 5000 Hz frequency range.
