Figure 2.

Examples of CAEP waveforms from a representative ONH participant. Responses to 500-Hz tones in Gaussian noise are shown from suprathreshold to threshold levels (shown as dashed red lines) for NoSo (left) and NoSπ (right) conditions. The NoSo threshold is 88 dB SPL and the NoSπ threshold is 80 dB SPL, resulting in a BMLD of 8 dB.
