Deafness and Hearing Loss
Deaf or hearing impaired people have either complete or partial hearing loss. These people often require the use of hearing aids or sign language to hear and communicate. Hard of hearing people are those who suffer from a form of partial hearing loss usually caused by aging or trauma.

How can a bacterial infection cause hearing loss?
Sudden hearing loss--at least 30dB in less than three days--is most commonly caused by cochleitis, a mysterious viral infection.
How do you approach a deaf person?
You can tap them or somehow make eye contact with them.
If they know sign language, you can wave your fingers up and down in their line of sight; this is a polite way of getting their attention. If they see you, you can put the fingers of your dominant hand in the palm of your other hand and make a brief rubbing motion - this means "excuse me."

They do; if the hearing person knows ASL. If the hearing person does not know ASL, it really wouldn't make any sense for them to do so.
Do deaf people think to themselves in signlanguage?
Yes, many deaf individuals think in sign language, particularly if they are native sign language users. Their internal monologue may involve visual and spatial representations of signs, as well as associated imagery. However, thinking processes can vary widely among deaf individuals, depending on their communication experiences and language exposure. Some may also think in spoken language or use a combination of both.
What is a loss of hearing due to aging?
Presbycusis is a gradual loss of sensorineural hearing that occurs as the body ages (presby means old age and -cusis means hearing)
Neuroscience studies have found that as we age, our cochlear tends to lose the ability to detect very high frequency sounds.
There is a sound you can search for that only people under the age of 25 can hear. It is called 'the mosquito' and it was used in some countries to deter youths from loitering at night time. It was found to be contradictory to the Declaration of Human Rights and ceased.
From what I understand, the more you damage your ear drums through frequent exposure to high volume music, the more you ear drum 'oval window' loses its ability to transduce sound into the neural electrical signal that we know as hearing. Hearing aids are quite effective nowadays in amplifying sound, so unless you have some sort of degenerative hearing disease, hearing can be restored.
How is conductive hearing loss different from sensory hearing loss?
Conductive hearing loss occurs in the outer or middle ear. (Something stuck in hear canal, perforated ear drum, breakdown in the ossicular chain)
Sensorineural loss occurs in the inner ear inside cochlea where the tinny hair cells have become damaged.
How often do you need to replace your hearing aid batteries?
There are different type of hearing aids batteries available in the market but I suggest to you all that you should purchase zink air battery or button cell battery with silver oxide. Batteries are toxic and should keep away from children.

On the basis of size it is divided in to four type which are listed below. 1. Size10 2. Size13 3. Size312 4. Size675 Life cycle of different battery are different according to there size and power average life of normal hearing aid battery is different according to the chart we described According to survey we find that different battery has different power life according to there size size10 battery average life is 66.3 hour and size312 battery average life is 76.4hour and size13 battery Average life is 109.1 hour and size675 battery average life is 172.4 hour.
What could cause sudden hearing loss in one ear?
Many drugs can cause temporary hearing loss..or intermittent hearing loss. Aspirin causes a ringing in the ears called tinnitus and various syndromes cause hearing loss such as Meniere's disease. Concussion, allergies and ear infection are also culprits.
If a medical student can lip read well, or can hire a signer/interpretor, the person could become a physician. However, with paying someone to sign/interpret, the cost of doing business would likely be high. As well, many hearing patients may feel uneasy or frightened if they can't fully communicate with the physician directly.
It may be more feasible to enter medical research fields.
Are deaf people allowed drive?
Absolutely. Being deaf does not effect your ability to drive.
Emergency vehicles have flashing lights besides sound for a reason.
When someone cannot sing in key and and do not realize that they are out of tune.
Hope this helped! :)

Do deaf schizophrenic people hear voices?
If the person was born totally deaf, then no, they would not hear voices, because they would have no concept of what a voice sounds like. They would exhibit other symptoms of schizophrenia, that do not involve sound.
Are hearing loss and hearing impairment the same thing?
No. Hearing loss depends on the decibel listened to and the period of time. Everyone is prone to having hearing loss.
How many decibels can damage hearing?
It's the high sound pressure deviation we measure as sound pressure level (SPL) at our eardrums. The threshold of pain is known in acoustics as the lowest strength of a stimulus that is perceived by the ear as painful. Because of the different sensitivity of the hearing of people it cannot be given an accurate value. You can find the following rounded values for threshold of pain in various audio articles and books:
140 dBSPL equivalent to 200 Pa
137.5 dBSPL equivalent to 150 Pa
134 dBSPL equivalent to 100 Pa
130 dBSPL equivalent to 63 Pa
120 dBSPL equivalent to 20 Pa
Sound pressure levels more than 140 dB will burst your eardrums.
Not necessarily. Only if the deafness was obtained genetically. For example, I am a deaf person, but it was not hereditary. Therefore, I will not have deaf children. However, if a deaf person is deaf from hereditary factors - (i.e. the mother is deaf or the grandfather is deaf) - it indicates that there is a gene that carries the deaf factor, which means that it is possible for a deaf person to have deaf children.
What kind of deafness Can result from a blood clot in the primary auditory cortex?
A blood clot in any part of the brain can result in a stroke. It may also cause local damage, reducing or removing the ability to hear properly.
Who was considered the father of education for the deaf in the US?
Define teacher>? The first teacher of signing was probally Laurent Clerc, a french citizen who had worked with deaf and Deaf people in France, and had helped in the development of ASL here.
Ear drums don't vibrate the echolocation that well to the cochlea , partially due to injuries or, from nature's laws of physics. Therefore, noises do not reach to the mind; "the consciousness". Hearing aids are recommended for the hard hearing.
