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 bats are safe from becoming deaf?
Bats are equipped with specialized adaptations that protect them from becoming deaf due to their high-frequency echolocation calls. They possess a unique muscle system in their middle ear that dampens the vibrations of their eardrums when they emit these loud sounds, preventing potential hearing damage. Additionally, their auditory system is finely tuned to detect echolocation frequencies while filtering out background noise, allowing them to navigate effectively without harming their hearing abilities. This combination of physiological adaptations ensures that bats maintain their acute sense of hearing throughout their lives.
Deafness can be hereditary or be "contracted" by listening to loud music. Working in a loud environment for an extended period of time without the proper protection can cause hearing loss.
Is it safe to use an ear hearing aid when I have an open sore within the ear?
You should not use a hearing aid when their is an open sore. Allow the sore to heal.
What is progressive deafness due to ossification in the bony labyrinth of the inner ear called?
otosclerosis
Conductive hearing loss occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). This type of hearing loss may occur in conjunction with sensorineural hearing loss or alone.
Progressive hearing loss that occurs in old age?
What is it call when Progressive hearing loss that occurs in old age
What is the lowest sound that humans can hear?
It depends on age etc.
but about 20 cps is the lower limit.
(Some like to claim 16)
What does the hearing aid do that makes you hear?
New technologies have allowed for hearing aids to really improve for the patient! In the past, the hearing aid was solely in the hard-of-hearing ear and mainly consisted of amplifying the exterior noise and channeling it into the inner-ear. Now, through bone-conductive technology, we are actually able to transmit sound through the human's bones into their inner ear.
This process was approved by the FDA and Sonitus Medical came out with the first hearing aid that was able to achieve this without the need of surgery. What happens is that the user wears a small microphone on their weaker ear. This mic picks up the sounds on that side of the persons head and wirelessly transmits it to a type of retainer that the user wears in their mouth. This device receives the signal and sends small vibrations through the molars and jaw towards the inner-ear on the healthy side. Once the vibrations get to the inner ear they are transferred in our minds as sound and the user is able to experience true hearing without the use of their bad ear. It really is remarkable.
What are four potential speech problems of children who are deaf or hard of hearing?
- Children with hearing loss comprehend and produce shorter and simpler sentences than children with normal hearing.
- Children with hearing loss often have difficulty understanding and writing complex sentences, such as those with relative clauses ("The teacher whom I have for math was sick today.") or passive voice ("The ball was thrown by Mary.")
- Children with hearing loss often cannot hear word endings such as-sor-ed. This leads to misunderstandings and misuse of verb tense, pluralization, nonagreement of subject and verb, and possessives.
- Children with hearing loss often cannot hear quiet speech sounds such as "s," "sh," "f," "t," and "k" and therefore do not include them in their speech. Thus, speech may be difficult to understand.
- Children with hearing loss may not hear their own voices when they speak. They may speak too loudly or not loud enough. They may have a speaking pitch that is too high. They may sound like they are mumbling because of poor stress, poor inflection, or poor rate of speaking.
- Children with hearing loss have difficulty with all areas of academic achievement, especially reading and mathematical concepts.
- Children with mild to moderate hearing losses, onaverage, achieve one to four grade levels lower than their peers with normal hearing, unless appropriate management occurs.
- Children with severe to profound hearing loss usually achieve skills no higher than the third- or fourth-grade level, unless appropriate educational intervention occurs early.
- The gap in academic achievement between children with normal hearing and those with hearing loss usually widens as they progress through school.
- The level of achievement is related to parental involvement and the quantity, quality, and timing of the support services children receive.
What are the pros and cons of teaching deaf children sign language?
Evaluating the pros and cons of teaching sign language to a child with a severe-to-profound hearing loss (who cannot benefit from the use of hearing aids) should take into account several important factors.
A child who is born with a hearing loss that is inherited genetically and whose parents are also deaf will grow up learning sign language. Using sign language, the child will communicate effectively with family members and probably an extended deaf community. Effective communication with family members is definitely a "pro" of teaching sign language to a relatively small proportion of deaf children.
However, a child relying exclusively on sign language typically is not able to communicate easily and effectively with most hearing persons. That's the primary "con" of teaching to a child who is deaf sign language as the primary method of communication. Most children with deafness are born to hearing parents.
Nowadays, the family of a child newly identified with profound hearing loss is always given the option of management first with hearing aids and then, after a trial period of 3 months or more, the possibility of a cochlear implant. A cochlear implant is a complex device that converts sound to electrical signals that activate the hearing nerve directly.
Cochlear implantation is followed by intensive auditory rehabilitation and speech-language therapy to develop effective oral communication (speaking and hearing). Children who receive a cochlear implant in the first few years after birth typically develop good speech and language skills.
Children benefiting from cochlear implantation go to school with hearing children, speak on the telephone, function quite well in various communication settings, and have the same opportunities for work and higher education as hearing children.
Informed decisions about communication method and education of children with deafness are generally made soon after birth by the child's parents, with accurate and up-to-date information supplied by audiologists, physicians, and other health care professionals.
Consideration of sign language doesn't need to be an either/or decision. Children with deafness who receive a cochlear implant during the first few years after birth can, with proper rehabilitation ,develop oral language like hearing children while they also also learn sign language. These fortunate children grow up essentially bilingual, just as children who are exposed on a daily basis to two languages (like English and Spanish) become naturally bilingual speakers.
Which frequency range of human hearing is most affected by hazardous noise?
3,000-6,000 Hz
+++
Noise at hazardous levels are so over the entire human audiological spectrum, but long-term exposure reduces the response from the highest frequency (18-20 kHz) downwards.
How do deaf people watch movies?
They use their eyes like everyone else. If you are asking how do they understand the dialogue, then the answer is, they either read the captions, or ask a hearing family member or friend to explain to them what the people were talking about.
there are different explanation for a person to be deaf.
like Helen Keller.some are inborn deaf, some get sick, and some person encounters an accident that causes them to be deaf.
Is the hearing of sounds within the body through a stethescope?
There are many sound that the body makes constantly: the heart beat, pulsing sounds, vascular sounds, breathing, etc. The reason that you don't typically notice them is because your brain is well adept at tuning the mundane and common sounds out. This is a wonderful thing, because if we were aware of all the sounds inside our bodies, we would never be able to focus on anything else. The best way to hear some of these sounds is to amplify them with a stethoscope.

What glue is best to repair a hearing aid?
This depends on what the problem is. If you are trying to repair a crack in the shell, Loctite is a good choice. If there is more advanced damage, or if you are repairing other parts of the hearing aid, it's best to take it in to be professionally repaired. If the hearing aid is in warranty you risk voiding the warranty by fixing it yourself. If it is older and out of warranty, there could be internal components that may be damaged by the glue. Good luck!
How do you explain noise greater then 85-90 decibels can cause loss of hearing?
That tells it all:
"Permitted Noise Exposure Time Guidelines - SPL"
Sound pressure level Lp and permissible exposure time t:
115 dB = 0.46875 minutes (~30 sec)
112 dB = 0.9375 minutes (~1 min)
109 dB = 1.875 minutes (< 2 min)
106 dB = 3.75 minutes (< 4 min)
103 dB = 7.5 minutes
100 dB = 15 minutes
97 dB = 30 minutes
94 dB = 1 hour
91 dB = 2 hours
88 dB = 4 hours
85 dB = 8 hours
82 dB = 16 hours
Lower dBs are said to be harmless.
If the person is born deaf thus this mean he is also mute?
No, but it is hard for people to talk when they cant hear themselves. they cant control the volume of their voice easily.
Is miracle ear better than a regular hearing aide?
