The aim of the study was (1) to investigate the development of identification of environmental sounds in children with Cochlear Implantation (CI) within four months from switch on (i.e. at 0, 2 and 4 months) and (2) to see the effect of family type in the perception of environmental sounds.
A longitudinal study design was utilized on a total of 18 children using CI within the chronological age range of 3 to 7 years. All participants underwent a closed set test of Environmental Sound Perception (ESP) to measure the longitudinal outcomes of ESP, at 0 (within 1 week of switch on), 2 months and 4 months of implant age. They were asked to identify the sounds by pointing at the picture representing the sound.
Results using One-way and Two-way ANOVA demonstrated that at 0 month of implant age, the scores were 0%. At 2 months of implant age the scores ranged from 0 to 25% and at 4th month the scores ranged from 0 to 40%. There was a statistically significant improvement observed in ESP at every 2 months of testing from 0 to 4 months of implant age. However, effect of family type revealed no significant differences between the performances across the implant age.
The current study reveals that identification of environmental sounds are one of the foremost benefits and early outcomes of CI in children. The perception of environmental sounds are constantly but gradually developing with increasing implant age. This information is useful to predict the performance of CI during rehabilitation and to set the therapy goals accordingly.
本研究的目的是（1）调查人工耳蜗植入（CI）儿童在开机后四个月内（即0、2和4个月时）对环境声音识别能力的发展情况，以及（2）观察家庭类型对环境声音感知的影响。
对18名年龄在3至7岁之间的人工耳蜗植入儿童采用纵向研究设计。所有参与者在植入年龄的0个月（开机后1周内）、2个月和4个月时，均接受了环境声音感知（ESP）的封闭测试，以测量ESP的纵向结果。他们被要求通过指向代表声音的图片来识别声音。
使用单因素和双因素方差分析的结果表明，在植入年龄0个月时，得分率为0%。在植入年龄2个月时，得分率在0%至25%之间，在第4个月时，得分率在0%至40%之间。从植入年龄0个月到4个月，每2个月的测试中，ESP均有统计学上的显著改善。然而，家庭类型的影响显示，在不同植入年龄阶段的表现之间没有显著差异。
本研究表明，识别环境声音是人工耳蜗植入对儿童最重要的益处和早期效果之一。随着植入年龄的增加，对环境声音的感知在持续且逐渐地发展。这些信息有助于预测康复期间人工耳蜗植入的效果，并据此设定治疗目标。
