Abstract：Objective To determine the value of mandarin acceptable noise level test and mandarin <br> hearing in noise test in assessing outcomes of hearing aids in older populations. Methods Mandarin accept-able noise level test (M-ANL) and mandarin hearing in noise test (signal-to-noise ratio=10dB) were conduct-ed in 20 subjects with presbycusis after they were fitted with hearing aids. Participants in this study were di-vided into an ANL<7 dB group and an ANL≥7 dB group according to a previous study by Nabelek et al. The International outcome Inventory for hearing aids (IOI-HA) was administered face-to-face foe IOI-HA sub-scale 1, sub-scale 2 and total scores. Correlations among M-ANL values and MHINT scores and IOI-HA scores were analyzed. IOI-HA and MHINT scores were compared between the two groups. Results 1) Pear-son correlation analysis showed no correlation between M-ANL values and IOI-HA sub-scale 1 scores or IOI-HA total scores (p> 0.05), but a negative association between IOI-HA sub-scale 2 and M-ANL values (r=-0.528, p<0.05). MHIN scores after hearing aid fitting showed a positive association with IOI-HA sub-scale 1, sub-scale 2 and total scores. 2) Two independent samples T test showed that there were no statisti-cally significant differences between the ANL<7 dB and ANL≥7 dB groups regarding the IOI-HA sub-scale 1, sub-scale 2 and total scores. 3) The average MHINT score was 78.64 ± 26.49 dB S/R for the ANL<7 dB group and 52.42±9.24 dB S/R in the ANL≥7 dB group, respectively (t=2.333, p=0.031). 4) Pearson correla-tion analysis showed that M-ANL values and MHINT scores were negatively correlated (r=-0.505, p=0.023). Conclusion M-ANL and MHINT tests show values in evaluating outcomes of hearing aid fitting. The M-ANL test is useful to predict the effects of hearing aid fitting, while the MHINT test can be used to evalu-ate the outcomes.
