Suppression of transient-evoked otoacoustic emissions was recorded from 29 members of the Louisiana Philharmonic Orchestra and 28 non-musician control subjects matched for age and gender. Binaural broad band noise was used as the suppressor stimulus in a forward masking paradigm. Results showed musicians to have significantly more suppression than non-musicians for both the right and left ears. Two possible explanations for this functional difference between groups are that moderately loud music serves as a sound conditioning stimulus and that music can be a mechanism for strengthening central auditory pathways which may influence the olivocochlear reflex arc. Possible explanations for this are discussed and ear, gender, and age differences within each group are examined. Additionally, middle-ear muscle reflex thresholds were found to be higher in musicians than non-musicians at some frequencies in some conditions.
从路易斯安那爱乐乐团的29名成员以及28名年龄和性别匹配的非音乐家对照受试者中记录了瞬态诱发耳声发射的抑制情况。在正向掩蔽范式中，使用双耳宽带噪声作为抑制刺激。结果显示，音乐家双耳的抑制情况均显著多于非音乐家。两组之间这种功能差异的两种可能解释是，适度响亮的音乐充当了一种声音调节刺激，并且音乐可能是一种强化中枢听觉通路的机制，这可能会影响橄榄耳蜗反射弧。本文讨论了对此的可能解释，并研究了每组内的耳朵、性别和年龄差异。此外，发现在某些条件下的某些频率上，音乐家的中耳肌肉反射阈值高于非音乐家。
