Arm Intervention/treatment
Experimental: Erchonia HLS
635 nanometers (nm) laser application
Device: Erchonia HLS
56 procedure administrations with the Erchonia® HLS™ administered by the subject at home: daily procedure administrations for 8 weeks.

Primary Outcome Measures :
  1. Total Score on the Tinnitus Handicap Inventory (THI). [ Time Frame: Baseline and 8 week ]
    The Tinnitus Handicap Inventory (THI) is a 25-item questionnaire to assess how tinnitus affects an individual's life. Each question is responded to as 'yes' (4 points); 'sometimes' (2 points) or 'no' (0 points). The individual scores for the 25 questions are added to get a total THI score from 0 to 100. The higher the total THI score, the greater the negative impact tinnitus has on the individual's life. Change in total THI score is calculated as total THI score after the one week procedure administration phase minus total THI score at baseline. A positive (+) change in total THI score indicates the negative impact of tinnitus on the individual's everyday life has worsened. A negative (-) change indicates the negative impact of tinnitus on the individual's everyday life has improved (lessened).
