摘要

背景和目的:与未接触音乐的训练相比,音乐训练在一些听觉和非听觉任务中表现出色。畸变产物耳声发射(DPOAE)输入输出函数可以是耳蜗非线性功能的指标。本研究的目的是评估和比较具有和不具有音乐能力的个体的DPOAE输入输出函数斜率的差异。方法:考虑20名年龄在18-25岁之间的正常听力个体。他们根据音乐能力问卷上获得的分数被划分为具有和不具有音乐能力的个体。对两组患者分别进行DPOAE输入输出函数分析。比较各组之间不同频率下DPOAE输入输出函数的斜率。结果:Mann-Whitney测试结果显示,在2000、3000、4000和6000赫兹的频率下,有音乐能力的人的斜率明显更陡。在1000和1500Hz时斜率没有显著差异。结论:斜率的增加表明具有音乐能力的个体的耳蜗功能相对较好。对音乐的感知增强可以引起耳蜗的变化,从而更好地欣赏音乐。

Assessment of Distortion Product Otoacoustic Emissions Input-Output Function in Individuals with and without Musical Abilities
Background and Aim: Musical  training  has shown to bring about superior  performance  in several auditory and non-auditory tasks compared to those without musical exposure. Distortion product otoacoustic emissions (DPOAE) input-output function can be an indicator of the non-linear functioning of the cochlea. The objective of this study was to evaluate and compare the differences in the slope of DPOAE input-output function in individuals with and without musical abilities. Methods: Twenty normal-hearing individuals were considered in the age range of 18–25 years. They were divided based on the scores obtained on the questionnaire of musical abilities, as individuals with and without musical abilities. DPOAE input-output function was done   for each of the two groups. The slope of the DPOAE input-output function was compared at different frequencies between the groups. Results: The results of the Mann Whitney test revealed that the slope was significantly steeper at 2000, 3000, 4000 and 6000 Hz in individuals with musical abilities. There was no significant difference in slope at 1000 and 1500 Hz. Conclusion: The increased steepness of the slope indicates a relatively better functioning     of the cochlea in individuals with musical abilities. The enhanced perception of music may induce changes in the cochlea resulting in a better appreciation of music.
