1. A 70-year-old male with bilateral moderate-to-severe SNHL (PTA 65 dB bilaterally) and word recognition score of 68% bilaterally is fitted with behind-the-ear (BTE) hearing aids. He reports benefit in quiet but difficulty in noisy environments. The signal processing feature most likely to improve speech understanding in noise is:
2. Tinnitus retraining therapy (TRT) is based on which neurophysiological model?
3. A child aged 8 years has normal hearing on pure tone audiometry but fails speech-in-noise testing and has academic difficulties. Behavioral audiometry and ABR are normal. The likely diagnosis and primary diagnostic test is:
4. Which hearing aid style provides the highest acoustic gain and is most suitable for a patient with profound hearing loss?
5. A 70-year-old retired factory worker complains of constant high-pitched bilateral tinnitus and sensorineural hearing loss greatest at 4 kHz. Tinnitus Retraining Therapy (TRT) uses which principle to achieve habituation?
6. Which type of hearing aid is most appropriate for a patient with a bilateral severe-to-profound sensorineural hearing loss who is not a cochlear implant candidate, wishes to use a hearing aid, and has adequate residual cochlear reserve?
7. A 70-year-old patient is being fitted with a hearing aid. The audiogram shows a moderately severe high-frequency SNHL with a sloping configuration (ski-slope pattern). Which hearing aid style and processing feature would most appropriately address this audiogram?
8. Tinnitus retraining therapy (TRT) is based on the neurophysiological model of tinnitus proposed by Jastreboff. According to this model, the persistence and distress of tinnitus is primarily attributable to:
9. Auditory processing disorder (APD) in a school-aged child manifests despite normal peripheral hearing thresholds on pure-tone audiometry. Which test specifically assesses central auditory processing?
10. A 70-year-old patient with moderate-to-severe presbycusis (sloping high-frequency SNHL) requires hearing aid fitting. The 'gain' of a hearing aid is defined as:
11. A 45-year-old patient presents with constant, high-pitched, unilateral right tinnitus of 6 months duration. Audiometry shows a notch at 4 kHz bilaterally with predominantly right-sided loss. Tinnitus matching localizes it to 4 kHz. Residual inhibition testing shows complete suppression of tinnitus lasting 30 seconds after masking tone presentation. This residual inhibition finding indicates:
12. On audiological assessment of a child with suspected auditory processing disorder (APD), which test specifically evaluates the brain's ability to process degraded or competing speech signals in the central auditory pathway above the brainstem?
13. A 70-year-old with bilateral sensorineural hearing loss (moderate, sloping audiogram) is prescribed hearing aids. The patient reports difficulty understanding speech in noisy environments despite adequate amplification. Which hearing aid feature MOST directly addresses this complaint?
14. Tinnitus Retraining Therapy (TRT) is based on which neurophysiological model of tinnitus?
15. In pure tone audiometry, air-bone gap greater than 10 dB indicates:
16. A 70-year-old man with bilateral moderately severe sensorineural hearing loss (averaging 65 dB HL) trials conventional hearing aids but finds them unsatisfactory due to poor speech discrimination in noise. The most appropriate next rehabilitation option is:
17. In tinnitus retraining therapy (TRT), the theoretical basis involves which neuroplasticity model?
18. A 60-year-old patient with bilateral mild-to-moderate high-frequency sensorineural hearing loss is being fitted with hearing aids. Regarding hearing aid selection, receiver-in-canal (RIC) hearing aids have what advantage over traditional behind-the-ear (BTE) aids?
19. Tinnitus retraining therapy (TRT) is based on the neurophysiological model proposed by Jastreboff. Its core principle involves:
20. Central auditory processing disorder (CAPD) is best diagnosed by:
21. On pure tone audiometry, the air-bone gap is the difference between air conduction and bone conduction thresholds. A maximal conductive hearing loss produces an air-bone gap of approximately:
22. Tinnitus Retraining Therapy (TRT) is based on the neurophysiological model by Jastreboff. The key principle underlying TRT is:
23. In otoacoustic emission (OAE) testing, distortion product OAEs (DPOAEs) are absent bilaterally in a neonate who passes automated ABR screening. This pattern suggests:
24. The candidate for bone conduction hearing aid (conventional headband type) rather than a conventional air conduction behind-the-ear hearing aid would be a patient with:
25. A patient with moderate bilateral SNHL is being fitted with a hearing aid. The most commonly prescribed hearing aid style that sits entirely in the ear canal and is cosmetically least visible is:
26. Tinnitus Retraining Therapy (TRT) is based on the neurophysiological model of tinnitus developed by Jastreboff. The fundamental mechanism targeted by TRT is:
27. In auditory neuropathy spectrum disorder (ANSD), which combination of audiological findings is characteristic?
28. On pure tone audiometry, a patient's air conduction threshold is 55 dB HL and bone conduction threshold is 30 dB HL in the same ear. The air-bone gap is 25 dB. This configuration is most consistent with:
29. Speech Discrimination Score (SDS) / Word Recognition Score (WRS) of <50% at maximum comfortable listening level despite appropriate amplification most commonly indicates pathology at which level?
