Word recognition scores of 0% in one ear with normal audiometric thresholds in the same ear most strongly suggest:
Answer: Pseudohypacusis (non-organic hearing loss)
Normal thresholds with 0% word recognition is a pattern inconsistent with organic pathology and strongly suggests non-organic hearing loss.
During pure-tone audiometry, the Stenger test is used when:
Answer: Unilateral non-organic hearing loss is suspected
The Stenger test exploits the binaural Stenger effect to detect feigned unilateral hearing loss by presenting tones to both ears simultaneously.
A Type Ad tympanogram is characterized by:
Answer: Abnormally high peak compliance
Type Ad (deep) tympanograms show abnormally high static admittance, often associated with ossicular discontinuity or a flaccid eardrum.
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:
Answer: 20%
A rollover index exceeding 0.45 (or a drop >20 percentage points) at high intensities is considered significant for retrocochlear pathology.
Which behavioral hearing test technique is most appropriate for a typically developing 8-month-old infant?
Answer: Visual reinforcement audiometry (VRA)
VRA is most appropriate from approximately 6 months to 2.5 years of age, using head-turn responses reinforced by animated toys.
The supra-aural earphone calibration standard requires audiometric zero at 1000 Hz to be set to:
Answer: 7 dB SPL
For TDH-type supra-aural earphones, audiometric 0 dB HL at 1000 Hz corresponds to approximately 7 dB SPL per ANSI standards.
High-frequency audiometry (above 8000 Hz) is particularly useful for monitoring ototoxicity because:
Answer: Cochlear damage from ototoxic drugs begins at the base and progresses apically
Ototoxic drugs damage the basal (high-frequency) cochlear region first, so extended high-frequency audiometry detects early changes before speech-frequency loss occurs.
