The primary endpoints were tinnitus loudness and tinnitus handicap inventory. The secondary endpoints were speech recognition, anxiety and sleep quality.

Here we show that after 24 month implant usage, the tinnitus cohort experience 58% reduction in tinnitus loudness (on a 0-10 scale from 4.3 baseline to 1.8 = -2.5, 95% CI: -2.7 to -2.2, p = 3 x 10^-6; effect
