Cochlear Synaptopathy: Potential Functional Implications for Musicians and Other Performing Artists

---

1.  A comprehensive test battery for musicians is recommended to include: Careful case history. Otoscopy, tympanometry, conventional air conduction and bone conduction threshold tests . DPOAE testing and extended high frequency threshold tests up to 16 kHz. All of the above

2.  Comprehensive care for musicians should include detailed case history with questions asking about: Tinnitus Hyperacusis Speech-in-noise understanding All of the above

3.  Music induced hearing disorders can potentially include: Hearing loss Tinnitus and/or hyperacusis Diplacusis and/or dysacusis All of the above

4.  Mice that experience TTS early in their lifespan experienced a selective loss of what type of cells when they were allowed to age? Outer hair cells Inner hair cells Spiral ganglion cells Fibrocytes

5.  Mice that experience TTS and are then allowed to recover show hidden permanent deficits. What are the hidden deficits? Permanent change in behavioral threshold. Chronic tinnitus. Lasting decrease in OAE amplitude. Lasting decrease in ABR amplitude.

6.  As mice age, they lose outer hair cells. This outer hair cell loss was associated with what permanent deficits? Lasting change in OAE threshold. Chronic tinnitus. Hearing in noise deficits. Lasting decrease in ABR amplitude.

7.  As mice age, they lose synaptic connections between inner and outer hair cells. This synapse loss was associated with what permanent deficits? Lasting change in OAE threshold. Chronic tinnitus. Hearing in noise deficits. Lasting decrease in ABR amplitude.

8.  Which of the following statements is the most accurate description of cochlear synaptopathy in humans? Diagnostic tests for cochlear synaptopathy in humans are available. Cochlear synaptopathy has been observed in human temporal bones, with synaptopathy increasing with age. Cochlear synaptopathy has been observed in human temporal bones, with synaptopathy increasing with noise exposure history. There is no evidence for cochlear synaptopathy in humans.

9.  Which of the following statements is the most accurate description of temporary noise induced functional deficits in humans? Exposure to loud sound can cause temporary changes in DPOAEs in humans. Exposure to loud sound can cause temporary changes in DPOAEs and behavioral thresholds. Exposure to loud sound can cause temporary changes in DPOAEs, behavioral thresholds, and word in noise tests. Exposure to loud sound does not cause temporary functional changes in humans.

10.  Chronic exposure to loud music: Does not result in damage to the ear and has no functional consequences. Can damage the ear but the pathology is usually minor and has no functional consequences. Can damage the ear and induce hearing disorders. Is not a concern because it is the listeners choice to participate in this activity.
