Ear Anatomy
The three parts of the ear
Outer, middle and inner ear
A professional devoted to the study of hearing disorders, assessment of hearing, hearing conservation, and aural rehabilitation
Audiologist
The name of the instrument used to look in ear
The otoscope
The transducer utilized to complete bone conduction testing
Bone oscillator
Symbol for right and left air conduction thresholds on audiogram
O and X
The three ossicles
Malleus, incus, stapes
The two systems within the scope of practice for an audiologist
Hearing and vestibular systems
The direction to pull ear during otoscopy
Up and back
(Superiorly and posteriorly)
The softest level that a person responds to a stimulus tone 50% of the time
Puretone threshold
Presbycusis (Aging) typically produces this type of hearing loss
Sensorineural
Begins with the pinna and external auditory meatus and terminates at the tympanic membrane
Outer ear
"Gold standard" organization for audiologists
ASHA (American Speech-Language and Hearing Association)
These abnormal landmarks can be found prior to otoscopy
Pit, tags, atresia/microtia, keloids
The purpose of masking
To keep the non-test ear "busy" while establishing results for the test ear
AC is worse than BC, and BC in normal range
Conductive hearing loss
The sensorineural mechanism is made up of these two parts
Inner ear and auditory nerve
Three practice settings for an audiologist
hospital, ENT office, university, private practice, schools, research
Three times to not perform otoscopy
The frequencies tested during a hearing screening
1000Hz, 2000Hz, 4000Hz
Difference between AC and BC of same ear is >10dB
Air bone gap
The portion of the ear responsible for hearing function.
Cochlea
Prevention, identification, assessment, rehabilitation, advocacy, education, practice settings
two abnormal otoscopic findings
Perforation, foreign body, excessive wax, active drainage
3 threshold Response task options for pediatrics
Conditioned Play Audiometry, Visual Reinforcement Audiometry, Behavioral Observation Audiometry
Four characteristics to describe an audiogram
Degree, type, configuration, laterality
