FIG. 4.
Sound localization responses for a representative control listener (C2) with the left ear plugged. A, C Responses toward 500 Hz were less affected by the earplug than responses towards the 3-kHz noise, as indicated by the higher r 2 value. All 3-kHz noises (C) were perceived at the hearing side (large positive bias +49° vs. +14° for 500 Hz). B, D Binaural hearing performance is good for both stimulus types (r 2 > 0.9, b small). Data pooled across presentation levels. The dashed gray line denotes the linear regression fit. r 2 coefficient of determination, g response gain, b bias, X indicates the plugged side.
