a Mean and one standard error of the SNR loss in each group. The higher the SNR loss, the worse the speech-in-noise performance. In the tinnitus group, the SNR loss in the left ear was significantly higher than that in the right ear (P = 0.034). b A scatter plot of the individual performance. Higher SNR loss represents poorer speech-in-noise performance. Points that fall below the diagonal indicate higher SNR loss in the right ear compared to that in the left ear. Only one of 14 tinnitus patients showed a score below the diagonal
