ABA Audiologic Assessment & Diagnosis 3

Question 1

Word recognition scores of 0% in one ear with normal audiometric thresholds in the same ear most strongly suggest:

Accepted Answer

Pseudohypacusis (non-organic hearing loss)

Answer

Normal thresholds with 0% word recognition is a pattern inconsistent with organic pathology and strongly suggests non-organic hearing loss.

Question 2

During pure-tone audiometry, the Stenger test is used when:

Accepted Answer

Unilateral non-organic hearing loss is suspected

Answer

The Stenger test exploits the binaural Stenger effect to detect feigned unilateral hearing loss by presenting tones to both ears simultaneously.

Question 3

A Type Ad tympanogram is characterized by:

Accepted Answer

Abnormally high peak compliance

Answer

Type Ad (deep) tympanograms show abnormally high static admittance, often associated with ossicular discontinuity or a flaccid eardrum.

Question 4

Rollover on a performance-intensity function for word recognition is defined as a PI-PB max minus PI-PB score at high intensities greater than:

Accepted Answer

20%

Answer

A rollover index exceeding 0.45 (or a drop >20 percentage points) at high intensities is considered significant for retrocochlear pathology.

Question 5

Which behavioral hearing test technique is most appropriate for a typically developing 8-month-old infant?

Accepted Answer

Visual reinforcement audiometry (VRA)

Answer

VRA is most appropriate from approximately 6 months to 2.5 years of age, using head-turn responses reinforced by animated toys.
