FIG. 5.

Individual interaural pitch matches and binaural fusion ranges for all HI listeners. Plotted as in Fig. 4. Plus (+) symbols indicate when the pitch matches were “out of range,” and low or high values indicate that the pitch match was below the lowest frequency tested or above that subject's highest comfortably audible frequency, respectively. Open squares at the top or bottom of fusion range lines indicate when the upper or lower limit of fusion could not be measured, respectively, due to limitations in the residual hearing frequency range or because fusion occurred up to the lower or upper limit of the frequency range tested.
