The deaf and hard of hearing (HOH) community is very diverse, differing greatly on the cause and degree of hearing loss, age at the onset, educational background, communication methods, and how they feel about their hearing loss. The authors also add that Deaf people "have found ways to define and express themselves through their rituals, tales, performances, and everyday social encounters. The term "hard of hearing" refers to those who have some hearing, are able to use it for communication purposes, and who feel reasonably comfortable doing so.
For everyone with a hearing loss, it is a matter of deciding whether to treat it as an audiological perspective or as a cultural lifestyle. The Center for Disease Control (CDC), National Center for Health Statistics, indicates that our 34 million Americans have a hearing loss. Of the 34 million Americans with a hearing loss, approximately 86 percent are hard of hearing and 14 percent are deaf. In Minnesota, approximately 67,623 individuals are deaf and approximately 429,606 are hard of hearing.
Permanent hearing loss can result from loud noise, especially with repeated exposure over long periods.
People living in rural areas are more likely to have a hearing loss than people living in metropolitan areas. Three high risk factors for hearing loss in infants and young children include heredity, congenital infection and recurrent or persistent otitis media (ear infection). Research conducted by the Early Hearing Detection and Intervention (EHDI) programs suggest that all infants be screened for hearing loss by one month of age and preferably before hospital discharge. American Sign Language (ASL) is the natural, visual-spatial language of the culturally deaf population in the United States and English-speaking parts of Canada. In terms of syntax, ASL follows a topic-comment formula, while English uses the Subject-Object-Verb canonical word order.

Hearing impairment, deafness, or hearing loss refers to the inability to hear things, either totally or partially.
Hearing loss refers to a diminished ability to hear sounds like other people do, while deafness refers to the inability to understand speech through hearing even when sound is amplified.
Degree of hearing impairment - a person's severity of hearing impairment is categorized by how much louder than "usual levels" sound volumes need to be set at before they can detect a sound.
Degree of deafness - any degree of deafness means the person cannot understand speech through hearing at any level of amplification. Sound waves enter the ear, go down the ear canal (auditory), and hit the eardrum, which vibrates.
This means that the vibrations are not passing through from the outer ear to the inner ear, specifically the cochlea. The ossicles may be impaired due to infection, trauma, or their fusing together (ankylosis). Hearing loss is caused by dysfunction of the inner ear, the cochlea, auditory nerve, or brain damage.


Long-term exposure to loud noises, especially high frequency sounds, is another common reason for hair cell damage. Sensorineural total deafness may be due to birth defects, inner ear infections, or head trauma.
On the next page we look at prelingual deafness, post-lingual deafness and unilateral and bilateral deafness.

The organ of hearing is the ear, which is divided into the outer, middle, and inner ear, each with its own role.

How a person "labels" themselves in terms of their hearing loss is personal and may reflect identification with the deaf community or merely how their hearing loss affects their ability to communicate. The audiological definition can be used­ -- that is, one that focuses on the cause and severity of the hearing loss and whether or not hearing can be used for communication purposes. It's all about choices, comfort level, mode of communication, and acceptance of hearing loss. Three out of 100 children suffer from middle ear infections that may cause a temporary hearing loss. It is a linguistically complete, natural language that shares no grammatical similarities to English and should not be considered in any way to be a broken, mimed, or gestural form of English. A patient with mild hearing impairment may have problems understanding speech, especially if there is a lot of noise around, while those with moderate deafness may need a hearing aid. Profound deafness means the person cannot hear anything at all; they are unable to detect sound, even at the highest volume possible. The vibrations from the eardrum pass to the three ossicles (bones called the malleus (hammer), incus (anvil) and stapes) in the middle ear.
It can be due to an excessive build-up of earwax, glue ear, an ear infection with inflammation and fluid buildup, a perforated eardrum, or a malfunction of the ossicles (bones in the middle ear). If the ear drum and middle ear are functioning properly, patients may benefit from a cochlear implant - a thin electrode is inserted in the cochlea, it stimulates electricity through a tiny microprocessor which is placed under behind the ear, under the skin. Connecting the middle ear with the nasopharynx is the eustachian tube, through which air enters to equalize the pressure on both sides of the tympanic membrane (eardrum). Generally, the term "deaf" refers to those who are unable to hear well enough to rely on hearing, and use it as a means of processing information.
Noise that is frequently over 90 decibels includes rock music, lawn mowers, power tools, kitchen appliances and farm equipment, etc. Deaf culture is a social, communal, and creative force of, by, and for Deaf people based on ASL. People who are born deaf find lip-reading much harder to learn compared to those who became hearing impaired after their had learnt to communicate orally (with sounds). Some people define profoundly deaf and totally deaf in the same way, while others say totally deaf is the end of the hearing spectrum.


These occicles amplify the vibrations, which are then picked up by small hair-like cells in the cochlea; they move as the vibrations hit them, the movement data is sent through the auditory never to the brain.
As humans get older, the hair cells lose some of their function, and our hearing gets worse. On the final page we take a look at how deafness is diagnosed and the available treatments for deafness and hearing impairment. In Western Europe and North America it is estimated that over half of all people over 70 years of age have hearing impairment caused by degenerated hair cells in the cochlea. As sound is conducted from the external ear to the inner ear, the sound waves undergo considerable transformation.
What about being hard-of-hearing and functioning as a member of both the hearing and Deaf communities? It’s also an attitude of the majority who do not view deafness as a disability, but one of many riches of diversity.
The tympanic membrane (eardrum), ossicles, and cochlea act as a mechanical transformer to concentrate the sound waves so that they can be picked up by nerve endings in the inner ear and transmitted to the brain.hearing aid an instrument to amplify sounds for those with hearing loss. More information on deaf culture can be found by accessing various links provided in the Resources and Website Links section. Those with sensorineural hearing loss (caused by injury to the vestibulocochlear nerve), or a mixed type, may have more trouble selecting a suitable hearing aid and may get less satisfactory results.Those wearing a hearing aid for the first time should have special training in its proper use. Often a person whose hearing has declined gradually will have lost the facility to ignore background noises. When one first tries a hearing aid, one's ears will be assaulted by the sounds of passing cars, of doors slamming, of telephones ringing. Training in how to filter out these noises and concentrate on the essential is necessary if the person is to get good results from the hearing aid. For best results, this should be combined with lessons in lipreading.A cochlear implant can help profoundly deaf persons recognize and interpret various sounds. A small electronic apparatus that amplifies sound and is worn in or behind the ear to compensate for impaired hearing.hearing aid an electronic device that amplifies sound used by people with impaired hearing. The microphone receives sound waves directed toward the person with hearing loss, then converts the sound waves to electrical impulses that are amplified with the aid of the power supply, and the receiver converts the electrical impulses back into sound vibrations.
Newer, programmable hearing aids can be customized on the basis of the characteristics of an individual's hearing loss. Electronic hearing aids traditionally consist of a microphone, an integrated circuit amplifier and an earpiece, often combined into a single device. Many include an electro-magnetic pickup for use in buildings or with telephones equipped with electro-magnetic sound radiation devices. Latest designs are intended for ear implantation and, instead of producing amplified sound from an earphone, apply output vibrations directly to the auditory ossicles, so eliminating feedback squeal.
The organ of hearing is the ear, which is divided into three sections, the outer, middle and inner ear.
Connecting the middle ear with the nasopharynx is the pharyngotympanic canal, through which air enters to equalize the pressure on both sides of the tympanic membrane (eardrum).hearing aidan instrument to amplify sounds for the hard of hearing.
