20Q: The Importance of Psychoacoustics in Clinical Audiology

---

1.  Which of the following audiological assessments is a psychoacoustic test of detection? Audiogram Acoustic Reflex Threshold Tympanogram Otoacoustic Emissions Testing

2.  Which of the following tests is based on the psychoacoustic principle of binaural lateralization and used in audiology to rule out pseudohypacusis or functional hearing loss? Dichotic Digits Stenger test Tone decay test Tinnitus Pitch Match Test

3.  Which of the following statements is true regarding sensorineural hearing loss and perceptual abilities? All listeners with SNHL experience severe deficits in the representation of spectral, temporal and binaural information. Listeners with SNHL experience deficits in the representation of spectral, temporal and binaural information to varying degrees. SNHL does not impact perceptual abilities unless the Pure Tone Average is 70 dB or greater. The impact that sensorineural hearing loss will have on perceptual abilities can be predicted by the audiogram.

4.  Which statement best describes how amplification impacts the perceptual distortions associated with sensorineural hearing loss? Hearing aids improve all perceptual distortions associated with sensorineural hearing loss. Amplification with compression may distort spectral and temporal cues, and amplification may reduce binaural cues. Amplification does not impact perceptual distortions associated with sensorineural hearing loss. Cochlear implants correct all perceptual distortions associated with sensorineural hearing loss.

5.  According to the author, how might psychoacoustics influence the way an audiologist provides amplification and audiological rehabilitation? An audiologist could provide counseling about realistic expectations with amplification to patients who have hearing loss and temporal processing deficits. An audiologist could provide communication strategies and other aural rehabilitation to patients who have hearing loss and temporal processing deficits. When selecting and fitting hearing aids, an audiologist could consider how the sound processing and features may impact an individual with specific perceptual deficits. All of the above
