N1m source strength in each condition.

<p>The x-axis depicts the respective tone positions. The y-axis denotes the mean N1m source strength. Red color symbolizes the random condition, and black the constant sequencing condition. Values in the silent condition are drawn with solid lines, and values in the noise condition are symbolized by dashed lines. Single colored asterisks mark significant differences between tones of the same sequencing condition. Double colored asterisks mark differences between tones of different sequencing conditions in the same respective position. Error-bars denote the 95% confidence interval limits of the arithmetic mean across subjects.
