What is the highest frequency sound that humans can hear?

Answer 1

"Ear". Microsoft Encarta Encyclopedia. CD-ROM. 2000."The maximum range of human hearing includes sound frequencies from about 15 to about 18,000 waves, or cycles, per second."15-18,000 Hz

Answer 2

The maximum range of human hearing includes sound frequencies from about 15 to about 18,000 waves, or cycles, per second."

Just a note on units: using the proper terms there give "... 15Hz to 18kHz". The Hertz has replaced the cycle per second as the standard unit of frequency.

As you get older it becomes more difficult to hear higher frequencies. 22 kHz seems to be the highest a baby can hear. But don't forget it depends very much on the loudness of the signal. Scoll down to the link of a site that can test a little your ability to hear these high frequencies.
The highest frequency an average human can hear is 20 000 Hz
The average human ear can hear up to about 20,000 Hertz, however, this number may vary based on the age of the person, as well as other factors.

Answer 3

That depends on the individual human. Younger humans in general are able to hear sounds at

higher frequency than older humans. Across a large human population the upper limit of human

hearing is generally considered to be somewhere in the neighborhood of 20 KHz (20,000 per second).

Answer 4

The human range is 20 to 20,000 Hz, though there is great variation between people and a gradual loss of hearing in the higher frequencies with age is normal.
Some dolphins and bats can hear frequencies up to 100 kHz. Elephants can hear sounds at 14–16 Hz, while some whales can hear subsonic sounds as low as 7 Hz in water.

Answer 5

The upper limit of human hearing is generally quoted as 20,000 Hz. However it varies from individual to individual and decreases with age.

Answer 6

About 20 kHz, for a young person. The highest frequency heard can be quite a bit lower for an older person.

Answer 7

Humans can typically hear sounds with frequencies up to around 20,000 Hz. Beyond this range, the sounds are considered ultrasonic and are not audible to the human ear.

Answer 8

20,000Hz
