Managing the Musician with Hearing Loss: Fundamentals and Diagnostics, presented in partnership with Salus University

---

1.  The term "damage-risk criteria" (DRC) specifies: The combination of sound level and duration that is considered to have equivalent hearing loss risk The maximum sound level of allowable exposure in a given country The maximum sound duration of allowable exposure in a given industry How much hearing loss can be expected from a sound exposure

2.  The Occupational Noise and Hearing Survey (ONHS) is best described as: A carefully controlled prospective study including members of both sexes and representative of race and ethnicity A cross-sectional study of the hearing sensitivity of adult, primarily Caucasian men exposed to factory noise A study that explained the genetic predisposition of individual susceptibility to NIHL A study describing the dose-effect relationship of noise on hearing that is repeated every 5-7 years

3.  What is a benefit of using in-ear monitors over floor-wedge monitors? The musician is protected from the sound exposure from the crowd. The musician gets a more consistent monitoring signal regardless of location on the stage. Both A and B None of the above

4.  What is the effect of a slit-leak of a musician's earplug that is not snuggly fitting in the ear canal? Increased attenuation in the high frequencies Loss of attenuation in the low frequencies Loss of attenuation in the high frequencies Increased attenuation in the low frequencies

5.  Which of the following is NOT a reason for immediate medical referral for an adult musician presenting with hearing loss? Concomitant dizziness Conductive component to the hearing loss Bilateral, symmetric tinnitus with a history of noise exposure Poor word recognition score with hearing loss asymmetry

6.  What is a risk of custom in-ear monitors? Sound quality is poor The device does not fit well in the ear Poor comfort Incredibly powerful hearing damaging device

7.  What technique did the presenter recommend be used when verifying performance of custom hearing protection by MIRE/real-ear system to help manage the measurement artifact created by introduction of possible slit leak from a probe microphone tube? Insert the probe tube through the musician's earplug filter Have the earmold lab build the probe tube into the body of the custom sleeve Liberal use of water-based lubricant along the sleeve and at the face of the earplug where the probe tube interfaces with the ear canal and earplug No intervention is needed: we don't care about low-frequency isolation

8.  Which of the following earmold impression techniques can be used to improve the comfort and performance of custom hearing protection devices? Take impression while musician is playing his/her instrument Let the impression material harden a little in the syringe before injecting it into the ear canal Place the otoblock no deeper than the 1st bend of the ear canal If using two-part silicone earmold impression material, use double the material for Part 1 as for Part 2

9.  Which audiological test is illustrative for organic hyperacusis, if the patient can tolerate it (so approach use of this test with caution)? ABR Acoustic reflex threshold Pure-tone audiometry SISI

10.  Which are included in our plan of care? Diagnostic testing Tinnitus questionnaire All are included in our plan of care Detailed history
