Specialty tests
What is the purpose for ABRs in the pediatric population?
finding thresholds when the child cannot complete behavioral testing due to age or other factors
what is the acronym for the behavioral test done on infants that REQUIRES a cross-check with ABR and OAEs?
BOA
What pathology is characterized by a sensorineural hearing loss with a notch at 4,000 Hz?
Noise induced hearing loss
What tymp and volume would you get with a TM perforation?
type B with large volume
What is the scientific name for the classification of a spider?
Arachnid
What is the purpose for ABR in the adult population?
Screening for acoustic schwannomas (benign tumors on auditory nerve)
Name and describe the test that is used to find thresholds for ages 6 months to 2 1/2 years. (2 steps)
Visual Reinforcement Audiometry
Conditioning: Condition child to look at toy in box whenever sound plays by presenting sound and flashing toy at same time.
Testing: present tone and see if child looks towards box. Have assistant distract child between presentations with simple toy to keep them looking forward until the signal us presented.
What is the term used for drug-induced hearing loss?
Ototoxicity
What tymp and volume would you get with otitis media that is in the process of healing (no fluid)?
type C, normal volume
What is one of the 2 mammals that can lay eggs?
Platypus and echidna
What is the general term for the test that is often used as a screening tool as it only takes a minute? This test looks presents sounds to the ear using a probe and a very sensitive microphone picks up responses generated from the OHCs in the cochlea.
OAEs (otoacoustic emissions)
Name and describe the test that is done for infants that are 0-6 months old.
Behavioral observation audiometry
Present speech and tones (speech slightly more reliable) at a moderate intensity and watch for an unconditioned response
What pathology is characterized by episodic dizziness, roaring tinnitus, and a sensorineural hearing decrease?
Meniere's
What tymp and volume would you get with an incomplete wax occlusion?
Type A with small volume
Which mammal has the longest vertebrae?
Giraffe
When we test pediatrics using ABR, what is the term used for the function we are specifically looking at?
Latency intensity function
Name and describe the test used for 2 1/2 to 4 year olds. (2 steps)
Play Audiometry
Conditioning: condition child to put toy in box (or other action) in response to a signal by holding child's hand with toy up to their ear and then moving their hand to the bucket when a moderate signal is presented.
Testing: child completes simple action in response to signal. May require reinforcement.
sudden sensorineural hearing loss
What tymp and volume would you get with discontinuity of the ossicular chain?
type Ad, normal volume
What is the largest animal? (its a mammal, perhaps surprisingly)
a blue whale
VNGs assess the vestibular system by looking at what? (this is a specific term)
nystagmus
Which 2 frequencies should you try to get thresholds for first when testing younger pediatrics?
500 Hz and 2,000 Hz
What is the pathology that is characterized by progressively decreasing hearing in 1 ear, unilateral tinnitus, dizziness, abnormally poor speech discrimination, and positive reflex decay?
Acoustic Schwannoma
What tymp and volume would you get with Otosclerosis?
type As, normal volume
What is a group of crows called?
a murder
