Hearing Test Flashcards
evaluates hearing loss by comparing air conduction to bone conduction
rinne test
hearing occurs through air near ear involving ear canal and eardrums
air conduction hearing (ac)
hearing occurs through vibrations picked up by the hard specialised nervous system
bone conduction hearing (bc)
rinne and webers test
test for hearing loss
occurs when sound waves are unable to pass through the middle ear to the inner ear can be caused by problems in the ear canal ear drum or middle ear
conductive hearing loss (CHL)
occurs when theres damage to any part of the specialised part of the specialised nervous system including auditor nerve hair cellist the inner ear and other parts of cochlea
sensorineural hearing loss
how many hertz is the tuning fork used in rinne and weber hearing tests
512-Hz
where is the tuning fork first and second placement in rinne hearing test
mastoid bone behind ear by ear canal
doctor strikes tuning fork and places in middle of patients head to see which ear hears better
weber test
air conduction time is twice as long as bone conduction time
normal hearing
bone conduction is longer than air conduction
conductive hearing loss
air conduction is heard longer than bone conduction but not twice as long
sensorineural hearing loss
sound best heard in abnormal ear
conductive hearing loss
sound heard best in normal ear
sensorineural loss
rinne both ears AC>BC without webers localistion
normal hearing
