Auditory Deprivation February 3, 2014 By Bob Page, Clinician What it is and how to protect yourself from its effects Auditory Deprivation Without treatment, you can have permanent and irreversible hearing loss Auditory Deprivation is a condition that occurs in individuals suffering from hearing loss where their brain loses the ability to interpret words due to a lack of stimulation over an extended period of time. This condition can affect hearing loss patients who do not wear hearing aids, wear old hearing aids or only wear one hearing aid when two may be necessary. Even those suffering from a mild hearing loss can be affected by this condition. If hearing loss is not treated, auditory deprivation can cause an irreversible loss of functionality. How does this happen? You must first understand the difference between hearing and understanding. Your ears function as instruments to collect sounds and deliver these sounds to your brain. The speech interpretation center of your brain processes these sounds into words. If your ears cannot hear the sounds, then your brain does not have anything to process. The lack of stimulation in this area of the brain causes you to lose the functionality of understanding speech. So, basically if you aren’t hearing the words, you eventually lose the ability to understand them. When our vision starts to fade, we usually wait to seek professional help until we absolutely need it. Any delay in seeking help is not usually a problem because glasses are able to correct the problem immediately. Treatment for hearing loss is quite different. The longer you delay seeking treatment for your hearing loss, the harder it will be to treat it. Those with profound hearing loss who have suffered for a number of years may not be able to regenerate some of their speech perception. However, most hearing losses can be sufficiently amplified with the use of hearing aids to allow for near normal to normal hearing. Hearing aids will help your ability to hear and thus, stimulate your brain to protect you from auditory deprivation. Auditory deprivation is not a guarantee if you suffer from hearing loss as long as you are proactive with your hearing health. Have your hearing tested, and if necessary find the appropriate treatment sooner rather than later. Hearing aids can be a tremendous help by providing the necessary stimulation your brain requires to continue to understand everyday speech. Auditory Deprivation is a “use it or lose it” issue, so it is imperative that you are take action today to ensure your ability to perceive speech does not continue to deteriorate over time.
CENTRAL AUDITORY PROCESSING DISORDER Our ear is divided in to outer hair, middle ear, inner ear, auditory nerve and central auditory nerves system. This type of problem found in all the ages from children to old age. Person suffering from auditory processing disorder will be able to hear in quite environment however the challenges will be observed in noisy situations. This is very complex disorder and needs long term attention. Behavioural testing as well as electro physiological testing helps in diagnosis.

Old age deafness is the loss of hearing that gradually happens in most of individuals as they grow older. This is one of the common conditions affecting elderly both male as well as female. Normally aging starts at the age of 45yrs in females and 55 in men. Commonly seen changes in auditory system are cochlear and auditory nerve damage. Hearing loss starts with high frequency and later it involve the low and mid frequencies. Common complaint these individual present with is I can hear the voices but cannot make out what they are talking. Hearing loss make it hard to enjoy talking with family and friends, leading to feelings of isolation. Aging affects both the sides equally. Regular hearing testing is required to monitor the hearing status and also it will help in planning the rehabilitation. Recent research suggests that ignoring age related hearing loss may end up with dementia or memory deficits. Audiogram done by qualified audiologist helps us for planning appropriate hearing aid selection and fitting. Digital hearing aids really help in improving speech understanding in quiet as well as noisy surroundings. Further details please contact: AARAV SPEECH AND HEARING CLINIC
Pediatric Hearing Evaluation is one of the challenging task for every audiologist. Detailed case history, selection of appropriate physiological electrophysiological and behavioural testing is a key. Established hearing thresholds helps us select proper hearing aid and auditory training/ auditory verbal therapy approach. Child need to be evaluated subsequently to measure the benefit of amplification device and therapy. If no significant benefit is obtained by hearing aid further, child should be subjected to cochlear implant evaluation. Aided Audiogram, radiological study and therapists feedback helps team to consider the child for cochlear implant. Cochlear implant has really changed the world of children with hearing impairment. The goal of team is to integrate the child in mainstream and should get every opportunity as any other child with normal hearing. #brainstem evoked response #otoacoustic emission #Digital Hearing Aid #Aided audiogram #auditory Verbal therapy
Ototoxicity (oto-means ear and toxic means side effect) Ototoxicity means certain drugs used to treat certain medical conditions in the body has a side effect on hearing or balancing organ situated in the inner ear. The effects of ototoxicity can be reversible and temporary, or irreversible and permanent. Hearing loss caused by this kind of medication tends to develop quickly. The first symptoms usually are ringing in the ears (tinnitus) and vertigo. Hearing usually returns to normal after you stop taking the medicine. But some medicines can cause permanent damage to the inner ear. Early intervention plays a key role in improving speech understanding. hearing loss will be treated either by bilateral Digital Hearing Aid fitting or cochlear implants. Hearing aid benefit depends on the site of damage in the inner ear or nerve.
#Otitis Media It is an inflammation in the middle ear (the area behind the tympanic membrane) that is usually associated with the fluid accumulation Fluctuating hearing loss nearly always occurs with all types of otitis media. In fact it is the most common cause of hearing loss in young children If this hearing loss is untreated repetitively will have difficulty in auditory processing please consult ENT/Audiologist for more details #Pure tone Audiogram

An otoacoustic emission (OAE) is a low-level sound emitted by the cochlea either spontaneously or evoked by an auditory stimulus. Specifically, OAEs provide information related to the function of the outer hair cells (OHC). Present OAEs in an ear indicates that hearing mechanism is normal till the level of outer hair cells. This cells plays very crucial role in hearing system i.e. amplification of the sound. OAE can be done in 1 day old baby. oae has advantages over BERA test. Easily done, takes almost 3-5 minutes, not much preparing required, many children can be screened in short duration. If child fail on OAE wil be subjected for diagnostic audiological evaluation. and further management will be carried out.
Pure tone Audiometery Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems. Pure-tone thresholds (PTAs) indicate the softest sound audible to an individual atleast more than 50% of the time. Hearing sensitivity is plotted on an audiogram, which is a graph displaying intensity as a function of frequency. Degrees of hearing loss Normal hearing (0-15 dB): At this level, hearing is within normal limits. Types of Hearing loss Conductive Sensorineural Mixed modalities of tone presentation are air and bone conduction. PTA is gold standard test in diagnostic audiology. Advantages of PTA - Medico-legal Purpose - Qualitative and Quantitative analysis - Pre and post operative comparison
