The range of human hearing includes frequencies from about 15 to about 18,000 cycles per second. This varies from one individual to another, especially at the higher frequencies. High frequencies usually become less audible with age.

What is the normal range of PAO2 - PaO2 for healthy young adults breathing room air?
10 - 15 mm Hg.
Damage to the basilar membrane is most likely to affect one's what?
Damage to the basilar membrane impairs hearing. More specifically, damage to cilia cells (tiny hairs within the B.M.) corresponding to the frequency of a sound result in the impairment of ones ability to hear that frequency. An average, a healthy young person is able to hear between 20-20,000 hertz and will have approximately 30,000 cilia. By middle age damage to cilia reduces the range of hearing to an average of 12-14,000 hertz.

Is hearing better for young or old people?

What is the frequency range of most people with good hearing?
The maximum human hearing range is 20Hz to 20,000Hz. 20Hz is actually more felt than heard, though a trained musician can identify the pitch at 20Hz. Only very young children and dogs can clearly hear a pitch at 20kHz, generally, and every human's ability to hear very high frequencies gradually shifts downward with age - that is normal. Even the very elderly, barring other hearing problems, can still generally hear from 40Hz to 4kHz as a minimum - about six and one-half octaves. Generally, a healthy adult can hear clearly in a range of 30-15,000Hz into their sixth decade of life.
What is the difference between audible and inaudible sound waves?
The difference is that an audible sound can be heard, an inaudible can't. The human ear can detect vibrations between 20 and 20,000 cycles per second (for a young person; for an old person the range is less), so that range would be audible, anything outside that range is inaudible.The difference is that an audible sound can be heard, an inaudible can't.

How much does the typical guaranteed life insurance cost per month?
It depends on what type of coverage you want, the company you go with, your age and health, and the amount of death benefit you're looking at. Most policies range from around $10 per month for a $100,000 death benefit for term insurance (a young healthy person), to $100 per month for $100K of whole life insurance (for a young healthy person). Check your local broker/agent for your specific pricing.
Which body type is described as having a young appearance?

The upper range of human hearing is approximately Hz.?
The human hearing range is commonly given as 20 to 20,000 Hz, though there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.
How do young people damage there hearing?
loud music
