Sensorineural Hearing Loss In Young Children

The ear is an extraordinary human organ that many people take for granted until it doesn’t function. It is the only device that allows the human to hear sounds in their environment. The ear is made up of many parts that distinguish various sounds through different means. The ear anatomy and physiology along with how sound waves are transmitted into meaningful sounds will help one understand how hearing loss occurs.

Long-term noise exposure is an example; this is due to the damage that the noise exposure can have on the sensory hair cells. Sensory hair cells are what allow you to hear and if damaged the ability to hear is reduced and these hair cells do not grow back. As Colin was a car mechanic this meant he will have been in contact and close proximity to loud equipment and machinery daily, this could have had a detrimental effect to his hearing and prevented him from hearing Mary. Other environmental factors include ototoxic drugs, genetic factors and cell damage and neural degeneration which are common effects of aging. Ototoxic drugs can effect hearing as they can damage the inner ear including the hair cells and also the auditory nerve, this is important as it carries the sound information to the

Conductive hearing loss is the loss of sound sensitivity produced by abnormalities of the outer and/or the middle ear. People with conductive hearing loss have an impaired air conduction and normal bone conduction. The middle ear should be filled with air, but when it is filled with fluid, the fluid prevents the sound vibrations from being transmitted efficiently to the inner ear. This type of hearing loss can be caused by otosclarosis, if there is fluid buildup behind the ear drum, which means that the Eustachian tube is not working, or if the ear drum has a perforation.

Between the ages of ten and thirty is when hearing loss generally begins. The beginning stage is called otospongiosis. The remodeling of the otic capsule is now

Peripheral hearing loss, in addition to other types of hearing loss, is very common among the elderly. For those who develop permanent, peripheral hearing loss in older age, there are two main etiologies. Exposure to severe acoustic trauma can cause hearing loss at any age. However, a life-time exposure of lower level environmental noise can also lead to hearing loss due to noise. In addition, the phenomenon of presbycusis, age related hearing loss, also occurs in a large number of elderly people. This paper seeks to untangle the connections and interactions between noise induced hearing loss and presbycusis in older adults.

While sensorineural deafness can be the result of tiny hair cells being damaged, this can also occur when the auditory nerve is damaged (Better Hearing Institute, n.d.). Sensorineural deafness changes the ability of hearing faint sound and reduce the intensity of sound, creating difficulties for the person suffers from it to understand others (hearcom, n.d.). The causes of sensorineural deafness may vary, the exposure to loud noises, aging, medicines, illnesses, head trauma, or malformation in the structure of the inner ear are all potential causes (Better Hearing Institute, n.d.). Genetic also play as a role in the cause of sensorineural deafness. While sensorineural hearing loss is irreversible, researchers have found a way to help the patients to be able to hear better. Through a cochlear implant, an electronic device that replaces the function of the damaged inner ear and provide sound signal to the brain, people who suffer from sensorineural hearing loss would be able to hear (cochlear,

According to the story, a hospital in Boston found that 1 in 5 teens suffer with some sort of hearing impairment which teen can hardly hear or cannot hear. The most common cause of a hearing impairment is noise. We are exposed to a lot of noise.

In conductive hearing loss there is a mechanical deficiency in sound waves from the external ear to the spiral organ. Other than the mechanical deficiency in sound waves, the spiral and neuronal pathways involved in hearing function normally. An example would be a blockage or deformity in the middle ear because it prevents ossicles from vibrating properly. A middle ear infection or a ruptured eardrum are common causes of hearing loss. This type of hearing loss can be treated with medication or surgery, but if it cannot be treated then the result is permanent hearing loss.

Age: As we get older, nerve cells inside the ear either get damaged or die, diminishing our ability to hear. About a third of people ages 65-74 suffer from age-related hearing loss. The ratio becomes one in every two seniors once they are 75 or older. It’s also

The age-dependent analysis of the degree of hearing loss plotted pure-tone air conduction thresholds at 500, 1000, 2000, and 4000 Hz, and pure-tone averages (PTAs) for 500, 1000, and 2000 Hz, against corresponding 95th percentiles.23 Similarly, pure-tone air conduction thresholds at 8000 Hz were plotted against corresponding 90th percentile values.24 Ninety-fifth percentile values for 500 , ment was prevalent among all age groups. A lesser percentage of subjects had hearing loss in the moderate to profound categories. Profound impairment was most prevalent in the oldest age group, although these profound losses were only observed in the highest frequencies. Figure 1B shows the type of hearing loss as a function of age of affected subjects.

Hearing loss may be caused by damage in the outer, inner or middle ear. It could even be the auditory nerve. Sometimes there is no damage and it could just be caused by a congenital defect, injury, disease, certain medications, exposure to loud noise, or it can be age related. There are about twenty five percent of people in the

The human body in itself is an incredible masterpiece, but particularly how we as humans hear and perceive sound is amazing. Our ears are used in various aspects of life including enjoying music, following directions, and just its use in everyday conversation. As we grow older our hearing abilities tend to decline which can be a natural part of the aging process. Hearing loss that is associated with older age is known as presbycusis (Huang, Q., & Tang, J. , 2010). There are more people that suffer hearing loss in their later years due to increased life expectancy (ŠESTIĆ, M. R., & MILIĆEVIĆ, S. (2013). As Frisina wrote, “in association with the recent expansion of the aged segment of our populace, age-related hearing loss-presbycusis-constitutes

In the United States, about 48 million people or 20 percent of the population is affected by hearing loss (Hearing Loss Association of America). According to Cole and Flexer (2008), “Hearing loss is the most common birth defect” (p. xi). Approximately 16,000 to 18,000 infants and young children are diagnosed with hearing loss every year. (Cole & Flexer, 2008).

As the experiment was conducted in a crowded classroom, the apparent mild hearing loss was due low frequency. The patient was still capable of hearing high frequency, such as speech.

Assessment for a hearing impairment is very important, a hearing screening test will separate you into two groups: a passing group and a failing group. The ones who pass the screening are presumed to have no hearing loss. If you fail you are in need of an extensive evaluation which would be performed by an audiologist and you may also need follow-up care from other professionals. Tests for hearing impairments can be performed any time from birth through adult years. According to the Hearing Loss Association of America “more than 7 million children are diagnosed with a hearing impairment, many of these can be present at birth, or they can develop later in life. The percentages rise when an infant is born
