How is the pressure variation in a sound wave amplified in human ear?
how is the pressure varition in a sound wave amplified in human ear
What were ear thermometers used for?
Ear Thermometers are used to take a person's internal temperature via the ear. The average human's normal temperature is 98.6 degrees Fahrenheit.
What is the function of a eustachian tube in a human?
This is the tube that connects the ear with the throat. Its function is to equalize air pressure on both sides of the eardrum to keep the eardrum from rupturing and to reduce pain that may be felt when air pressure is reduced. When a person yawns or swallows, the eustachian tube opens, and some of the air in the middle ear may pass into the throat, adjusting the pressure in the middle ear to match the pressure in the outer ear.
Is the ear only function for hearing?
The Eustachian Tube, part of the ear, provides a connection between the middle ear and the mouth. This permits equalization of the air pressure in the middle ear with the pressure in the surrounding environment and prevents the problems and pain associated with excess pressure on the ear drum.Yes. Your ear has got the balancing apparatus located in the inner ear.
What main regioin of the human ear contains the ear canal?
Outer ear

How many lbs of pressure does it take to rip off a human ear?
The average is seven pounds.
How many pounds of force does it take to pull off an ear?
Depending on the sharpness of the blade, the ear is easily removed with little pressure. There are no bones or other problems with removal. A child could easily remove an ear with a common steak knife.
Why do you have ear pain when you take a flight?
Change of atmospheric pressure.
What is the human perception of intensity?
Our ear drums with the ear/brain system are moved only by sound pressure motions. The sound pressure is the effect, but the sound power (sound intensity) of the source is the cause.
What is the stirrup doing in the human ear?
It's a part of the "transducer" that converts air sounds (large, low pressure) into liquid sounds (low amplitude, high pressure) - it connects the ear drum to the inner ear (a thin section of the skull.

What is the difference between a human's ear to a rabbit's ear?
Rabbits have long external ears. Frogs do not have external ears. Or, maybe they have some kind of hole at most. Take a look at some pictures of frogs.
Human ear is sensite to sound intensity ranging in db min and max?
That is not correct. The human ear drums are only sensitive to the sound pressure variations. Also the microphone diaphragms are moved by the amplitude of sound pressure variations. At 0 dBSPL, the threshold of hearing, the sound pressure is 20 micropascals. At 134 dBSPL, the threshold of pain, the sound pressure is 100 pascals.

In which part of the ear does hearing take place?
"Hearing" - the conversion of sound into nerve impulses - occurs in the inner ear. The outer and middle are concerned with changing pressure waves in air into pressure waves in a liquid.
Human ear is sensite to sound intensity ranging from db?
The human is is not sensitive to sound intensity (energy), but the human ear is sensitive to sound pressure or to sound pressure level (SPL). It is ranging from 20 micropascals to 150 pascals, that is a SPL of 0 dB (threshold of hearing) to 137.5 dB (threshold of pain).
