Sensorineural hearing loss is the most common type of hearing loss, occurring in 23% of population older than 65 years of age. Infections, such as meningitis, are a common cause of hearing loss in children where it occurs in approximately 20% of those with streptococcus pneumoniae meningitis (Heckenberg et al 2011).
Noise induced hearing loss is a permanent hearing impairment resulting from prolonged exposure to high levels of noise.
Children who are born prematurely or contract certain infections in utero are at a higher risk of hearing loss (Hille et al 2007, Roizen 2003). While very unusual, acoustic neuromas or metastatic cancer (particularly breast) can be a source of hearing loss.
Sudden hearing loss (SHL) is defined as greater than 30 dB hearing reduction, over at least three contiguous frequencies, occurring over 72 hours or less.
Sensory presbyacusis is caused by loss of sensory elements in the basal (high-frequency) end of the cochlea with preservation of neurons. Cochlear conductive presbyacusis is caused by thickening of the basilar membrane caused by deposition of basophilic substance.
Because presbycusis occurs in some individuals as they age but not in others, genetic or environmental factors must also play a role in its development (Liu & Yan 2007). In conductive hearing loss, the second most common form of hearing loss, sound is not transmitted into the inner ear. Images marked as copyright Northwestern University were developed with the support of a National Institutes of Health (NIH) grant to Northwestern University Dept. The American Hearing Research Foundation is a non-profit foundation that funds research into hearing loss and balance disorders related to the inner ear and is also committed to educating the public about these health issues. It’s another fact why hearing loss should be treated carefully- in order to grow and stay healthy; the ‘downstream’ neural parts of the hearing system involve input from the ‘upstream’ sensory parts. The reasons of sensorineural hearing loss can be put into two major categories: Congenital and Acquired. Sensorineural hearing loss will mean you may have issue on understanding, When present in both ears, even when speech seems loud enough. Remedy for sensorineural hearing loss varies on the severity of your hearing loss and it also depends whether you are affected in one ear or both. Hearing aids can help people with mild to moderate sensorineural hearing loss in both ears.
If you have severe issue and hearing aids are no longer working for you then you may want to learn more about cochlear implants. CROS hearing aid is the most common treatment solution; if you have severe to profound sensorineural hearing loss in one ear. You have a right to know your Hearing Aid Audiologist's & Speech language pathologist's qualifications.
We are very happy with the proper suggestions offered by the audiologist about selection of right type of hearing aid. Bengal Speech provides very good & affordable hearing aid solutions for any kind of hearing problem. Conductive hearing loss is often temporary and may be improved with medical or surgical procedures. Assistive listening devices (ALDs) or Hearing Assistive Technology (HATS). ALDs, such as FM systems, require the person speaking to wear a microphone.
In this condition, the inner ear works, but there is a problem that keeps the brain from recognizing and interpreting sound correctly. Sensorineural hearing loss (SNHL) occurs when there is damage to the inner ear (cochlea) or to the nerve pathways from the inner ear to the brain.


Sometimes a conductive hearing loss occurs in combination with a sensorineural hearing loss. Send Home Our method Usage examples Index Contact StatisticsWe do not evaluate or guarantee the accuracy of any content in this site.
The outer ear includes the auricle, the external auditory canal, and the lateral surface of the tympanic membrane (TM).
Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear damage). One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech.
Much research has focused on the detection of genetic causes of hearing loss, and many of them can now be diagnosed at an early age (Blanchard et al 2012, Dror & Avraham 2009, Kochhar et al 2007, Kokotas et al 2007, Robin et al 2005, Xing et al 2007). Risk factors that correlate with hearing loss in premature infants include hypoxia, mechanical ventilation, hyperbilirubinemia, very low birth weight, and the use of ototoxic medications.
It occurs most frequently in the 30- to 60-year age group and affects males and females equally. These patients have symmetrical, high-frequency sensorineural hearing loss (as shown in Figure 3). Medical conditions that are common in the elderly, such as diabetes and stroke, may also increase the risk of hearing loss with aging (Bainbridge et al 2010, Helzner et al 2005, Maia & Campos 2005, Schreiber et al 2010).
Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, tympanosclerosis (as shown in Figure 4), external or middle ear infections (otitis externa or media), allergy with serous otitis media, trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane.
Now we know that in most of the cases this problem originates from the inner ear rather than from the hearing nerve. It can be either inherited or generated by abnormal development in the fetal moments of life. You may have difficulty locating sounds or hearing in background noise, when present in one ear.
It is an electronic device which is surgically implanted- so to stimulate the hearing nerve directly, it bypasses the damaged inner part of the ear. It is due to problems with the inner ear or damage to the hair cells or nerves inside the inner ear. Cochlear implants are used when the hearing loss is too severe to be treated with hearing aids.
The person’s voice is then transmitted into the child’s hearing aids, cochlear implants, or earphones.
The middle ear includes the medial surface of the TM, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve.
These conditions are relatively common in premature infants, and the majority do not go on to develop hearing deficits. Hearing loss in adults surviving pneumococcal meningitis is associated with otitis and pneumococcal serotype. Race and sex differences in age-related hearing loss: the Health, Aging and Body Composition Study.
Though, we continue to group these two issues together, as the inner ear and the hearing nerve are connected and require working together. Maternal rubella or German Measles was a common cause of congenital hearing loss before the development of a vaccine. These contain age-related hearing loss, trauma, noise exposure from machinery or firearms and meningitis.
Cochlear implants transform sound waves to electrical impulses in a way that imitates your natural hearing.


Sometimes, a bone conduction implant can be great option for you, if you have normal hearing or mild hearing loss in your good ear.

Your child’s audiologist (health care professional who specializes in hearing problems) can tell you which type of hearing loss your child has. For someone to hear, sound signals must travel from outside the ear through the ear canal and eardrum into the inner ear. If fluid buildup behind the eardrum is the cause, a tiny tube may be inserted into the eardrum to help drain the fluid.
Assistive listening devices allow the child to hear the person speaking without distracting background noise. To hear words correctly, the brain must recognize and interpret the sounds that are sent to the brain. Your child's audiologist (a health care professional who specializes in hearing problems) can tell you which type of hearing disorder your child has. The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals). The National Institute of Health reports that about 15 percent of Americans aged 20 to 69 have high frequency hearing loss related to occupational or leisure activities. If the loss is minor, then avoidance of noise and ototoxic medications may be an appropriate treatment.
These vibrations travel to the inner ear where tiny “hair cells” (cilia) and the hearing nerve turn the vibrations into nerve impulses (signals).
Conductive hearing loss results when sound becomes partially or fully blocked in the outer or middle ear. Your health care provider can tell you more about what’s causing your child’s hearing loss and how it can be treated or managed. The brain then senses what we “hear.” With sensorineural hearing loss, the hair cells or nerves are damaged and do not send the signals needed for hearing to the brain. FM systems can be used in classrooms to help children with hearing loss hear their teachers. With APD, something keeps the brain from properly processing or interpreting the sounds that make up a word or words. Trauma is more likely to affect hearing in patients who suffer a temporal bone fracture or are older in age (Bergemalm, 2003). Because of occupational risk of noise induced hearing loss, there are government standards regulating allowable noise exposure.
Scientists think it may be related to problems with the hearing nerve, but more research needs to be done. People working before the mid 1960s may have been exposed to higher levels of noise where there were no laws mandating use of devices to protect hearing. Occasionally, persons with acquired deafness can be treated surgically with a surgically implanted device, a cochlear implant.
There are hearing tests available to check for ANSD that can be done by your child's audiologist. With hearing loss, either a temporary blockage or a permanent problem within the ear or brain keeps sound from being heard or understood.
