Figure 2: PMTF thresholds at 2 kHz as a function of noise level for one normal-hearing subject (circles) and one sensorineurally impaired subject (triangles). Peak thresholds have filled symbols and valley thresholds have open symbols. The threshold for the brief tone without noise was 24 and 71 dB SPL for the two subjects, respectively
