Auditory Processing Disorder and Blast Trauma

---

1.  Although more widely recognized in the UK and Australia, a common cause of acoustic trauma in the US is: Otosclerosis Working in a call center Listening to music Presbycusis

2.  This cause of acoustic trauma results in progression of symptoms over a lifetime: Presbycusis Noise exposure Electrocution Traumatic brain injury (TBI)

3.  Blast injuries result in damage to: The peripheral auditory system The central auditory system Both A and B Only the physical structures of the ear

4.  Common auditory issues reported after acoustic trauma can include: Tinnitus Difficulty hearing in background noise Peripheral hearing loss All of the above

5.  The underlying etiology thought to result in tinnitus and/or hyperacusis in patients exposed to acoustic trauma is: Cochlear synaptopathy Inner hair cell damage Presbycusis Central auditory dysfunction

6.  Assessment of auditory processing skills in a patient who has experienced acoustic trauma should include: DPOAEs Speech in noise testing Pure tone assessment All of the above

7.  Pure tone audiometric findings for a patient who has experienced an acoustic trauma are likely to demonstrate: A severe to profound sensorineural hearing loss A mild conductive hearing loss A unilateral hearing loss A "normal" audiogram based on pure tone description

8.  The most common auditory deficit noted for those that have experienced acoustic trauma is: Temporal processing disorder Auditory memory Speech discrimination Both A and C

9.  Appropriate treatment for those that have had acoustic trauma is: Fitting of amplification, even in view of a "normal" audiogram Listening training such as with the LACE or CLEAR Use of digitally modulated (DM) system All of the above

10.  A medical treatment thought to assist with improvement of hearing and tinnitus following acoustic trauma is: Steroid treatment Hyperbaric oxygen treatment Vasoactive agents Carbogen
