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
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.
What are the effects of air pressure have on the human body?
imbalanced pressure can cause nose bleedin and also if you tavel about and thru many and different areas of pressure your ear kinda blocks but u can "fix" it by yawning
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.
How many muscles in a human ear?
There are 3 muscles in the human ear. Interestingly cats, although small has 32 muscles in their ears.
What is a human tube?
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.
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.
How many moving parts are in the human ear?
The middle ear, outer ear, and inner ear are the three parts of the ear.
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.
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.
