5—repeating steps 3-4 until an approximate match is found with a resolution of no more than one octave

6—adjusting the tone up or down by 7 notes at a time

7—grading the tone by the subject as either higher or lower in tone than the perceived tinnitus tone

8—repeating steps 6-7 until an approximate match is found with a resolution of no more than 7 notes

9—adjusting the tone up or down by half notes

10—grading the tone by the subject as either higher or lower in tone than the perceived tinnitus tone

11—repeating steps 9-10 until an approximate match is found with a resolution of no more than half a note

12—adjusting the tone up or down on a continuous scale

13—grading the tone by the subject as either higher or lower in tone than the perceived tinnitus tone

14—repeating steps 12-13 until an approximate match is found such that no further adjustments in tone produce a perceived improved match (“personalized tinnitus tone”)

15—saving the personalized tinnitus tone information including wavelength, frequency and amplitude, in a computer memory

16—generating by means of computer software, a plurality of sine clusters, wherein a sine cluster comprises at least three sine waves of similar amplitude but varying frequency, each sine wave separated by a phase difference of between 10 degrees and 90 degrees, and wherein at least one of the tones is the personalized tinnitus tone
