Random Info We Didn't Know
This test can be used as a speech screening tool in adults
What is the SLUMS?
This test doesn't show type of loss, only asymmetry
These are the three types of bone conduction
What is 90 dB and a change of .02 mL?
Rollover is considered significant when it reaches this number or higher
What is .4?
An 18 month old child should know approximately this many words
If the patient hears the sound for less time than the examiner during the Schwabach test, then they have this type of hearing loss
What is sensorineural?
This type of bone conduction involves movement of the head resulting in movement of the stapes in and out of the oval window
What is inertial (ossicular)?
Confirming a contralateral threshold must have these three things
What is a repeatable reflex at threshold, a present reflex 5dB above threshold, and an absent reflex 5dB below threshold?
This test involves a low frequency (500/1000Hz) tone being presented over 10 seconds at about 90-105 dB
What is reflex decay?
These three things are the components of a probe on a tympanometer
What are the probe tone generator (speaker), microphone, and tube connected to air pump?
If the patient hears the sound in one ear instead of the midline during the Bing test, it can mean these two things
What is conductive loss heard in the poorer ear and sensorineural hearing loss in the better ear?
This type of bone conduction transmission involves pressure put on the membranous labyrinth by the vibrations compressing the bones of the skull
Hint: it creates a traveling wave
What is distortional?
Acoustic reflex pathways are based on what type of ear
Bonus: they are NOT based on this type of ear
What is the stimulus ear?
Bonus: What is the measurement ear?
A strong sign for retro pathology is shown when the patient hears the sound for this many seconds or less
What is 5 seconds?
These three terms are used to describe the different layers of the tympanic membrane
What is epithelial, fibrous, and membranous?
This test involves striking the tuning fork, placing it 1-2 inches in front of the ear, then repeating the process on the mastoid
What is the Rhinne test?
This type of bone conduction involves the escaped energy from the unoccluded ear that hits the TM, stimulating the inner ear
What is osseotympanic?
A normal threshold of 65-90 dB could indicate these three things
Bonus: If a reflex is reduced (present <60 dB), they have this type of loss
Bonus Bonus: If a reflex is elevated (present >100 dB) they may have these two type of losses
Bonus Bonus Bonus: If a reflex is completely absent, they could have one of these three types of losses
What is normal hearing, mild cochlear loss, and conductive loss?
Bonus: what is a cochlear loss?
Bonus Bonus: what is conductive loss and retrocochlear loss
Bonus Bonus Bonus: What is moderate or greater cochlear/conductive loss or retrocochlear loss?
In a tone decay test, slow decay and rapid decay are associated with which type of pathologies, respectively?
What is cochlear and retrocochlear?
TOAEs use this type of stimulus, whereas DPOAEs use this type
What is a click and tones?
If a patient hears the sound the same when the ear canal is closed off vs when it's open during the Bing test, then the patient has this type of hearing loss
A patient has the following reflexes:
Right Ipsilateral: Normal
Right Contralateral: Elevated
Left Ipsilateral: Absent/Elevated
Left Contralateral: Normal/Elevated
The patient likely has this site of lesion
What is a mild middle ear pathology?
The SISI test, used to predict cochlear pathology, uses a pure tone presented at this intensity level, which is then increased by this many decibel increments?
Bonus: A patient who scores between 0-70% on this test will have these three options for pathology
Bonus Bonus: If a patient scores 75% or more on this test, they are positive for this type of pathology
What is 20 dB and 1 dB increments?
Bonus: what is normal hearing, conductive, retrocochlear?
Bonus Bonus: what is cochlear?
