Chapter 14 Flashcards
what part of the ear does conductive hearing loss effect?
the outer or middle ears
why is conductive hearing loss is more prevalent than sensorineural in children?
because of the high rates of otitis media in early childhood
what causes sensorineural hearing loss?
outer or inner cell damage in the cochlea
damage to the auditory nerve
why is sensorineural hearing loss is more prevalent than conductive in adults?
because it is the cochlea and auditory nerve that are most readily affected by aging, noise exposure, illness, disease, and injury
Definition of recruitment
a reduced tolerance for loud sounds caused by cochlear damage
Definition of tinnitus
a ringing or buzzing sound in one or both ears
Definition of signal-to-noise ratio (SNR)
hearing loss and loss of speech clarity due to inner hair cell damage
true or false: people with SNR loss require a greater signal intensity than those with normal hearing
true
Cause of neural loss
damage to the auditory nerve
hearing loss goes undetected and/or untreated in more than ____% of adults with hearing loss
75%
Definition of presbycusis
progressive hearing loss that occurs as a result of aging
true or false: presbycusis is more prevalent and severe in women
false - men
what is presbycusis characterized by?
hearing loss in the high frequency range of sounds
what percentage of the population have a hearing loss?
approximately 10%
true or false: incidence of acquired hearing loss increases dramatically with age
true
how is hearing loss classified?
etiology, manifestation, and severity
true or false: conductive Hearing Loss is more common in children
true
symptoms of conductive Hearing Loss
a slight to moderate loss of hearing in one or both ears
is conductive Hearing Loss permanent?
no – it is amenable to medical or surgical intervention, so often it is temporary
what are 4 causes of conductive Hearing Loss?
otosclerosis
ear wax blockage
otitis media
damage to outer and middle ear structures
Definition of otosclerosis
a condition in which abnormal bone growth develops around the ossicles
true or false: otosclerosis occurs twice as commonly in women than in men
true
true or false: sensorineural hearing loss is more common in children
false - more common in adults
true or false: damage to outer hair cells results in difficulty with hearing acuity
true
true or false: damage to inner hair cells results in SNR loss
true
symptoms of sensorineural hearing loss
a decrease in both acuity and a loss of clarity
is sensorineural hearing loss permanent?
typically, yes – it can be treated effectively with amplification, but hearing cannot usually be restored
what are the most common causes of sensorineural hearing loss?
presbycusis and noise exposure
four focus areas in assessment of hearing loss
hearing acuity (or degree of loss)
type of loss
cause of loss
speech perception ability in quiet and in noise
what is the most effective treatment approach for adult hearing loss?
a comprehensive plan that combines counseling, fitting of amplification devices, and aural habilitation
true or false: most third-party payers do not reimburse for hearing aids or adult aural rehabilitation services
true
what does aural rehabilitation focus on?
auditory skill building concerns
the ability of the person with hearing loss to relearn how to listen
