  Hearing (sense) - Wikipedia, the free encyclopedia
Hearing, or audition, is one of the traditional five senses, and refers to the ability to detect sound.
In human beings, hearing is performed by the ears, which also perform the function of balance, a sense in itself but not one of the traditional list (due to Aristotle).
Snakes sense infrasound through their bellies, and there is evidence that whales and elephants may use it for communication.

 MSN Encarta - Hearing Aid
Hearing aids have the same basic components as any public-address system, but all the components are miniature and the amplified sound is delivered to the ear of only the hearing-aid user.
The microphone, amplifier (consisting of transistors and integrated electronic circuits), miniature receiver, and battery of a hearing aid are enclosed either in a chassis or shell, which is worn behind or within the ear or in the stem or temple portion of eyeglasses.
If the hearing loss is caused by malformation of the ear canal or impaired function of the middle ear, a small vibrator may be clamped against the mastoid bone behind the ear with a headband; the sound is conducted by the vibrator through the bones of the head to the inner ear.

 Co-Brand: The Daily Cat   (Site not responding. Last check: 2007-11-07)
Hearing is an important part of a cat's ability to hunt and fulfill his design as nature's perfect predator.
Humans can hear frequencies from about 20 hertz to 20 kilohertz, dogs from about 20 hertz to 40 kilohertz, and cats from about 30 hertz to 60 kilohertz.
Hearing is a large part of a cat's life, and Christensen says it is important to try to shield cats from loud, high-pitch noises such as sirens, which can greatly disturb them.

 O. Orkin Insect Zoo: Basic Facts--Insect Senses
Most sense organs of insects are microscopic in size and are found on their body wall.
Sense organs, or sensilla, that function for taste and smell always have at least one small hole, or pore, through which the chemical molecules enter the organ.
Most of the sense organs that respond to touch are small hairs with a nerve at their base.

 Neuroexam.com - Hearing and Vestibular Sense (CN VIII)
In conductive hearing loss, bone conduction is greater than air conduction, because bone conduction bypasses problems in the external or middle ear.
In sensorineural hearing loss, air conduction is greater than bone conduction in both ears (as in normal hearing), however, hearing is decreased in the affected ear.
Hearing loss can be caused by lesions in the acoustic and mechanical elements of the ear, the neural elements of the cochlea, or the acoustic nerve (CN VIII).

 Hearing—Information about Hearing, Communication, and Understanding
Students may believe that because each sense is specialized for a particular type of sensation, senses function by themselves and do not interact with one another or with the rest of the body.
Research into hearing and communication is providing a scientific foundation for understanding the anatomy, physiology, and genetics of the hearing pathway, as well as the social and cultural aspects of human communication.
Hearing loss often begins when a person is in his or her 20s, though it may not be noticed until the person is in his or her 50s.

 Riddle of Humanity: Lecture Seven
The physiologists are finally recognising and distinguishing the senses of life, of movement and of balance from one another, and they have begun to treat the senses of warmth and touch separately.
Hearing is bound up with the organs of hearing, at least principally so, but it needs more besides — hearing involves much more of the organism than just the ear, which is what is normally thought of as the region of hearing.
The eye is alive, the ear is alive, that which is the foundation of all the senses is alive; the basis of touch is alive — all of it is alive.

On bicycling, the sense of hearing and headphones
The sense of balance, the sense of touch and the kinesthetic, proprioceptive sense (sense of body positioning), make it possible to ride a bicycle even with your eyes closed.
But the role of headphones in causing bicycle accidents is, in my opinion, deeply confused by faulty assumptions about the sense of hearing, and by ill-conceived laws which place headphones in a special category separate from other factors affecting hearing.

 Phonak hearing systems - Technology of hearing systems   (Site not responding. Last check: 2007-11-07)
The right choice of hearing instrument type and technology is determined by the individual hearing loss and anatomical features of the ear.
Within the hearing instruments, acoustic signals are transformed at high speed and with great precision into a binary code.This allows much more complex calculations and adjustment of the amplified signal than is possible with analog technology.
Hearing instruments with analog signal processing are not programmed via a PC but are adjusted manually by a hearingcare professional using a fine screwdriver.

 Comments on Technology: What is the Best Hearing Aid?
What we do have are relative comparisons relative to a person's previous or other hearing aids, to various adjustments on the one being tried, or to internalized predictions by the audiologist on what performance this person should obtain.
But they don't answer the question that many people have, e.g., "is there some other hearing aid or other speech processing strategy than can help me hear better?" Certainly, there are other dimensions of hearing aid usage that we are concerned with, such as the quality of sounds and the comfort of listening.
Still, the most significant dimension of all, the reason why people wear hearing aids in the first place, is the improvement of speech comprehension, and this is the one that still virtually remains in the "trial and error" stage By now, we should be able to do better.

 The incredible Sense of Hearing
From there the fibers continue to the medial geniculate complex of the thalamus and from where they reach the primary auditory memory center of the auditory cortex in the area known as Broadmann 41 and 42.
Auditory function is a very difficult subject to comprehend due primarily to the diversity of cells and type of tissues that takes place in the processing of a signals reaching the ear.
The efficiency of the ear is such, that if the eye was forced to distinguish the tremendous difference between the sound of a cannon and a whisper, it is likely that the person would have to protect the eye externally.

Our hearing mechanisms accomplish these tasks by sensing sound waves, which are changes in air pressure, and converting these changes into electrical signals that the brain can analyze and interpret.
Although hearing begins with the ear flap or pinna, the receptor cells that change sound energy into the electrical currency of the nervous system lie deep inside the temporal bone of the skull.
The ability to hear is not found as widely in the animal kingdom as some other senses (e.g., touch, taste and smell); it is restricted mainly to vertebrates and insects.

Description: For whatever reason, this character's hearing is not as sharp as it should be.
This may mean that the character cannot smell certain odors, or perhaps smells things differently than from other people (for example, what may smell like perfume to a "normal" person may smell like bug spray to a person who suffers this Disadvantage).
