Final Exam: Audiology

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 (Behavioral Observation Audiometry).

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.

Which animal has a cochlea that most resembles a human's cochlea?

Chinchilla.

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.

Visual Reinforcement Audiometry; Conditioning involves training the child to look at a toy in a box when sound plays, and testing involves presenting a tone to see if the child looks toward the box.

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 the general term for the test that is used as a screening tool that only takes a minute?

OAEs (otoacoustic emissions).

Name and describe the test for infants that are 0-6 months old.

Behavioral observation audiometry; Present speech and tones 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.

When testing 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.

Play Audiometry; Conditioning involves training the child to put a toy in a box in response to a signal, and testing involves the child completing a simple action in response to the signal.

Name and describe the pathology that requires immediate treatment from an ENT for the best chance of hearing recovery.

Sudden sensorineural hearing loss.

What tymp and volume would you get with discontinuity of the ossicular chain?

Type Ad, normal volume.

What do VNGs assess in the vestibular system?

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 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.
