The purpose of the present study was to investigate vocal singing performance of hearing-impaired children with cochlear implants (CI) and hearing aids (HA) as well as to evaluate the relationship between demographic factors of those hearing-impaired children and their singing ability.
Thirty-seven prelingually-deafened children with CIs and 31 prelingually-deafened children with HAs, and 37 normal-hearing (NH) children participated in the study. The fundamental frequencies (F0) of each note in the recorded songs were extracted and the duration of each sung note was measured. Five metrics were used to evaluate the pitch-related and rhythm-based aspects of singing accuracy.
Children with CIs and HAs showed significantly poorer performance in either the pitch-based assessments or the rhythm-based measure than the NH children. No significant differences were seen between the CI and HA groups in all of these measures except for the mean deviation of the pitch intervals. For both hearing-impaired groups, length of device use was significantly correlated with singing accuracy.
There is a marked deficit in vocal singing ability either in pitch or rhythm accuracy in a majority of prelingually-deafened children who have received CIs or fitted with HAs. Although an increased length of device use might facilitate singing performance to some extent, the chance for the hearing-impaired children fitted with either HAs or CIs to reach high proficiency in singing is quite slim.
本研究旨在调查使用人工耳蜗（CI）和助听器（HA）的听力受损儿童的声乐演唱表现，并评估这些听力受损儿童的人口统计学因素与其歌唱能力之间的关系。
37名语前聋人工耳蜗植入儿童、31名语前聋助听器佩戴儿童和37名听力正常（NH）儿童参与了本研究。提取录制歌曲中每个音符的基频（F0），并测量每个演唱音符的时长。使用五个指标来评估歌唱准确性中与音高相关和基于节奏的方面。
人工耳蜗植入儿童和助听器佩戴儿童在基于音高的评估或基于节奏的测量中表现均明显低于听力正常儿童。除了音程的平均偏差外，在所有这些测量中，人工耳蜗植入组和助听器佩戴组之间均未观察到显著差异。对于两个听力受损组，设备使用时长均与歌唱准确性显著相关。
大多数接受人工耳蜗植入或佩戴助听器的语前聋儿童在音高或节奏准确性方面的声乐演唱能力存在明显缺陷。尽管增加设备使用时长可能在一定程度上促进演唱表现，但佩戴助听器或人工耳蜗的听力受损儿童达到高水平歌唱能力的机会相当渺茫。
