Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [ Time Frame: 84 days ]
    Safety and tolerability assessed based on comparison of adverse events vs. placebo

  2. Change in low frequency hearing thresholds measured by pure tone audiometry [ Time Frame: 56 days ]
    Co-primary efficacy endpoint; assessment of hearing by pure tone audiometry

  3. Change in Words-in-Noise Test score [ Time Frame: 56 days ]
    Co-primary efficacy endpoint; assessment of word recognition by Words-in-Noise Test


Secondary Outcome Measures :
  1. Change in tinnitus severity [ Time Frame: 56 days ]
    Tinnitus Functional Index (0-100) where higher score is worse outcome

  2. Change in tinnitus loudness [ Time Frame: 56 days ]
    Tinnitus Functional Index Question #2 -- How Strong or Loud was your Tinnitus? (0-10) where higher score is worse outcome

  3. Change in vertigo severity [ Time Frame: 56 days ]
    Vertigo Symptom Scale (0-60) where higher score is worse outcome

  4. Change in aural fullness [ Time Frame: 56 days ]
    Aural Fullness Scale (0-10) where higher score is worse outcome

  5. Change in dizziness [ Time Frame: 56 days ]
    Dizziness Handicap Inventory (0-100) where higher score is worse outcome
