Figure 2. MTMI noise caused changes in CAP responses.

Figure 2

(A) Under the 90-dB SPL click acoustic stimulation, the 1DPN group showed an increased CAP threshold, and this parameter recovered in the 1WPN and 1MPN groups. (B) CAP peak-to-peak amplitudes under different click stimulations in the noise exposed groups. (C) Under the tone burst acoustic stimulation, CAP thresholds were elevated in the noise exposed groups at different frequencies. (D) Under the tone burst acoustic stimulation, CAP peak amplitudes were suppressed in the noise exposed groups at different frequencies. (E,F) AM-CAP responses were suppressed in different frequency modulation depths. (E) 20 kHZ carrier at 80 dB SPL strength, coupled with a modulation frequency of 996 Hz. (F) On a 60 dB SPL white noise exposure backgrounds (NEBs). (Control: n=10, 1DPN: n=8, 1WPN: n=8; 1MPN: 12).
