2 Topics To Be Discussed Ear Anatomy and Physiology Signs of Hearing Loss in AdultsCauses of Hearing LossHearing Loss Treatment OptionsTinnitusSigns of TinnitusTinnitus Treatment Options
3 Anatomy and Physiology of the Ear OuterMiddleInner ear
4 Anatomy and Physiology of the Ear Outer EarConsists ofthe auricula or pinnathe external acousticmeatus
5 Anatomy and Physiology of the Middle Ear EardrumOssicles
6 Anatomy and Physiology of the Inner Ear Cochlea/Hearing OrganVestibular Canals/Balance Organ
7 Acoustic Nerve (8th)The vestibular/auditory nerve runs in the internal auditory canal and the peripheral end organs to the central nervous system (CNS) Nerve..
8 Diagnostic Tools Otoscopy OAEs (Otoacoustic Emissions) Tympanometry (Middle Ear Test)Pure tone and Speech Audiometry (Sound Booth)Auditory Brainstem Response(8th Nerve and Hearing Thresholds Estimation)
9 Common MythsHearing loss affects only "old people" and is merely a sign of aging.Actually it is the reverse of what most people think. The majority (65%) of people with hearing loss are younger than age 65.
10 Common MythsThere are more than six million people in the U.S. between the ages of 18 and 44 with hearing loss, and nearly one and a half million are school age.Hearing loss affects all age groups.
11 “If I had a hearing loss, my family doctor would have told me” Common Myths“If I had a hearing loss, my family doctor would have told me”Not true! Only 13% of physicians routinely screen for hearing loss during a physical. Since most people with hearing impairments hear well in a quiet environment like a doctor's office, it can be virtually impossible for your physician to recognize the extent of your problem. Without special training, and an understanding of the nature of hearing loss, it may be difficult for your doctor to even realize that you have a hearing problem betterhearing.org
12 Common MythsHearing might be at the bottom of the medical checklist, but it might be the number one medical cause of your problems.Why?
13 Signs of Gradual Hearing Loss in Adults The perception that people are speaking too soft or mumbling.Frequent misinterpretation of what is being said.Difficulty understanding conversations on the phone.
14 Signs of Gradual Hearing Loss in Adults/ Continuation… Difficulty understanding conversations in different environments: restaurants, theater, automobile, family reunions, seminars or places of worship.Blocked or stuffy feeling in the ears.Ringing in the ears.betterhearing.org
15 Prevalence of Hearing Loss In US 3 in 10 people over age of 60 have hearing loss;1 in 6 baby boomers (ages 41-59), or 14.6%, have a hearing problem1 in 14 Generation Xers (ages 29-40), or 7.4%, already have hearing lossAt least 1.4 million children (18 or younger) have hearing problemsIt is estimated that 3 in 1,000 infants are born with serious to profound hearing loss.betterhearing.org
16 Types of Hearing Loss Conductive hearing loss Hearing loss is categorized by which part of the auditory system is damaged.Conductive hearing lossSensorineural hearing lossMixed hearing lossRetro-cochlear hearing loss
21 Damage to Outer or Middle and Inner ear Mixed Hearing LossDamage to Outer or Middle and Inner ear
22 Causes of Conductive Hearing Loss Ear infection (Otitis)AllergiesPoor Eustachian tube functionPerforated eardrumBenign tumors (growths along the outer and middle ear)Impacted earwax (cerumen)Presence of a foreign bodyFluid in the middle ear from coldsAtresia (Anotia)
23 Causes of Conductive Hearing Loss Microtia and AtresiaEar malformationsPE tube: Surgical tube to drain fluid in middle ear
24 Causes of Conductive Hearing Loss External Otitis (Inflammation due to infection of ear canal)Impacted Wax
25 Ear Drum Perforation with a Q-Tip When cotton tipped applicators are used to clean out ear wax, there is a risk of breaking the ear drum (perforation). Although we realize that this is commonly done, we recommend against using cotton tipped applicators, hair pins, and similar devices to clean the ear.
26 Causes of Sensorineural Hearing Loss SNHL reduces the ability to hear faint sounds. Even when speech is loud enough to hear, it may still be unclear or muffled. Some possible causes of SNHL include:IllnessesDrugs that are toxic to hearingHereditaryAging (Presbycusis)Head traumaMalformation of the inner earExposure to loud noiseAuditory nerve occupied lesion/ (8th) tumors
28 Presbycusis Hearing Loss due to Aging Causes:There is no known single cause for age-related hearing loss. Most commonly, it is caused by changes in the inner ear that occur as you grow older. However, your genes and exposure to loud noises (such as from rock concerts or loud machinery) may play a large role.
29 Presbycusis Hearing Loss due to Aging The following factors contribute to age-related hearing loss:Family history (age-related hearing loss tends to run in families)Repeated exposure to loud noisesSmokingCertain medical conditions (Diabetes) and medications (Ototoxics) also contribute to age-related hearing loss.
30 Presbycusis Hearing loss related to Aging Prevalence: About half of all people over the age of 65 have some amount of age-related hearing loss.Impact in life style: The loss of hearing occurs slowly over time.It is most difficult to hear high-frequency pitch sounds. (ex: speech of women and children)As hearing gets worse, it may become difficult to hear sounds at lower pitches. (ex: men’s voices)
31 Presbycusis (Age Related Hearing Loss) It becomes difficult hearing things in noisy areas like restaurants.Hard time distinguishing high-pitched sounds such as "s" or "th" from one another.Other people's voices sound mumbled or slurred.Ringing in the ears and lack of tolerance to loud sounds is reported.
35 Retro-cochlear Hearing Loss 8th nerve (Auditory nerve) tumorAuditory Neuropathy (Connection between Cochlea and auditory nerve)Problems in the Auditory path from the cochlea to the auditory section in the brain (Auditory Processing Issues)
36 Hearing Loss Treatment options MedicationSurgeryTypes of Amplification:- Hearing Aids-Cochlear Implants (CIs)-Assisted Listening Devices
40 Hearing Aid Technology - Enhances speech intelligibility- Sound flows from one environment tothe other- Wind block & Echo blockAutomatic phone programFeedback (Whistle control)“Go with your specific needs and do not compare with others”
41 Assisted Listening Devices FM systems Bluetooth loopsAmplified Close captioned TVPhones
52 The cycle of tinnitusStressAnxiety LevelTinnitus
53 The Impact of TinnitusThoughts and emotions: annoyed, bothered, depressed, anxious or angryHearing: the sound of the tinnitus competes with or masks speech or environmental sound perception.
54 The Impact of TinnitusSleep: tinnitus interferes with the ability to fall asleep. It can also make it more difficult to get back to sleep when awaking up in the middle of the night because of the tinnitus.Concentration: difficulty focusing on a task because of the loudness of the tinnitus.
55 Tinnitus Treatment Options Multiple TreatmentsAvoidance of dietary stimulants:coffee, tea, cola, etc.Smoking cessationAvoid medications known to causetinnitus
56 Tinnitus Treatment Options Amplification (Hearing Aids)Sound GeneratorsAcupunctureMedication (Xanax)Counseling Tinnitus retraining therapyNeuromonics (customized, music therapy, through a tinnitus evaluation/ tinnitus pitch match/frequency/Hypersensitivity Levels)
57 Thanks to LIFE’s 2011 Grant to UCF Communication Disorders Clinic Tinnitus TreatmentNeuromonics, music therapy, was used to treat tinnitus and hyperacusis in an autistic female. It has proven to help reduce her tinnitus, hyperacusis, anxiety levelsand improve her ability to focuswhile in speech therapyand school.
