The purpose of this study was to investigate the effect of symmetrical, asymmetrical and unilateral hearing impairment on music quality perception. Six validated music pieces in the categories of classical music, folk music and pop music were used to assess music quality in terms of its 'pleasantness', 'naturalness', 'fullness', 'roughness' and 'sharpness'. 58 participants with sensorineural hearing loss [20 with unilateral hearing loss (UHL), 20 with bilateral symmetrical hearing loss (BSHL) and 18 with bilateral asymmetrical hearing loss (BAHL)] and 29 normal hearing (NH) subjects participated in the present study. Hearing impaired (HI) participants had greater difficulty in overall music quality perception than NH participants. Participants with BSHL rated music pleasantness and naturalness to be higher than participants with BAHL. Moreover, the hearing thresholds of the better ears from BSHL and BAHL participants as well as the hearing thresholds of the worse ears from BSHL participants were negatively correlated to the pleasantness and naturalness perception. HI participants rated the familiar music pieces higher than unfamiliar music pieces in the three music categories. Music quality perception in participants with hearing impairment appeared to be affected by symmetry of hearing loss, degree of hearing loss and music familiarity when they were assessed using the music quality rating test (MQRT). This indicates that binaural symmetrical hearing is important to achieve a high level of music quality perception in HI listeners. This emphasizes the importance of provision of bilateral hearing assistive devices for people with asymmetrical hearing impairment.
本研究的目的是调查对称、不对称和单侧听力障碍对音乐质量感知的影响。使用六首经验证的古典音乐、民间音乐和流行音乐类别中的乐曲，从“愉悦度”“自然度”“饱满度”“粗糙感”和“尖锐度”方面评估音乐质量。58名感音神经性听力损失患者[20名单侧听力损失（UHL）患者、20名双侧对称听力损失（BSHL）患者和18名双侧不对称听力损失（BAHL）患者]以及29名听力正常（NH）的受试者参与了本研究。听力受损（HI）受试者在整体音乐质量感知方面比NH受试者有更大困难。BSHL受试者对音乐愉悦度和自然度的评分高于BAHL受试者。此外，BSHL和BAHL受试者较好耳的听力阈值以及BSHL受试者较差耳的听力阈值与愉悦度和自然度感知呈负相关。HI受试者在这三类音乐中对熟悉乐曲的评分高于不熟悉的乐曲。当使用音乐质量评分测试（MQRT）进行评估时，听力受损受试者的音乐质量感知似乎受到听力损失对称性、听力损失程度和音乐熟悉度的影响。这表明双耳对称听力对于HI听众实现高水平的音乐质量感知很重要。这强调了为不对称听力障碍患者提供双侧听力辅助设备的重要性。
