Correlation between Mandarin acceptable noise level and cortical auditory evoked potential in young normal-hearing listeners
To investigate the correlation between Mandarin acceptable noise level (M-ANL) and cortical auditory evoked potential (CAEP), and to explore the possible mechanism leading to individual differences in M-ANL values.

Summary: | To investigate the correlation between Mandarin acceptable noise level (M-ANL) and cortical auditory evoked potential (CAEP), and to explore the possible mechanism leading to individual differences in M-ANL values.
Thirty listeners aged 22-33 years with normal hearing were selected as the study subjects, and the M-ANL test and CAEP test were performed respectively. The most comfortable level (MCL), maximum background noise level (BNL), M-ANL and CAEP values of each subject were recorded. The latency of each wave of P1, N1, P2, N2, P300 and the amplitude of P1-N1, P2-N2, P300 in CAEP were recorded for each subject. SPSS 25.0 was used for statistical analysis to explore the correlation between the MCL value, BNL value and M-ANL values and the latency of P1, N1, P2, N2, P300 and P1-N1, P2-N2, P300 amplitudes of CAEP.
①The MCL value and M-ANL value were positively correlated with the P2 latency of CAEP, and the correlation coefficients were 0.404 and 0.400, respectively, and the differences were statistically sig |
