Abstract:
Objective To explore the feasibility of the application of music test materials in acceptable noise level (ANL) test.Methods We chose Mandarin proficiency test material,Mandarin music and accompaniment music to produce ANL test materials.The background noise was babble noise.A total of 40 normal hearing young people conduct ANL tests.Results The most comfortable loudness (MCL) obtained under the Mandarin short text test material,Mandarin music test material and accompaniment music test material were 39.10±7.43,43.85±9.53 and 44.10±10.83 dB,respectively.The maximum background noise level (BNL) were 37.91±8.65,44.52±11.23,43.65±12.89 dB HL,ANL values were 0.98±4.90,-0.90±3.78,0.45±4.65 dB S/N,respectively.The MCL and BNL values of Mandarin music test materials and accompaniment music test materials were higher than those of Mandarin short text test materials (P＜0.05),but there was no significant difference between MCL and BNL values in Mandarin music test materials and accompaniment music test materials (P ＞ 0.05).There was no significant difference in ANL among the three test materials (P＞0.05).Conclusion The music test material can be applied to the acceptable noise level test.The MCL value and the BNL value were higher under the music test material,which indicating that the acceptance of the music is higher in normal hearing people,whether or not the music test material containing lyrics has no effect on the ANL test results.
