Basal auditory functions and early verbal communication skills were examined in young, profoundly deaf children with hearing aids or a cochlear implant. The hearing aid users (n = 23) were subdivided on the basis of their (unaided) hearing thresholds into: group A (pure tone average (PTA) at 0.5, 1 and 2 kHz: 90-100 dB HL); group B (PTA: 100-110 dB HL); and group C (PTA > 110 dB HL). All the children with a cochlear implant (n = 20) had a profound sensorineural hearing loss with a PTA that exceeded 120 dB HL. Functional hearing was evaluated by means of basal sound identification. The child's communication abilities with hearing aids or a cochlear implant were assessed using structured observations on the Scales of Early Communication Skills for Hearing Impaired Children. The basal auditory functions on a sound identification level improved over time in the cochlear implant users and groups A and B. Hardly any improvement was seen in group C. The performance of all the groups (either hearing aid or cochlear implant) on the Scales of Early Communication Skills for Hearing Impaired Children at 6 months after fitting the device and at later evaluations, was close to the average level for their age.
对佩戴助听器或人工耳蜗的重度失聪幼儿的基础听觉功能和早期言语交流技能进行了检查。助听器使用者（n = 23）根据其（未佩戴助听器时的）听力阈值被分为：A组（0.5、1和2千赫处的纯音平均听阈（PTA）：90 - 100分贝听力级）；B组（PTA：100 - 110分贝听力级）；以及C组（PTA > 110分贝听力级）。所有人工耳蜗使用者（n = 20）均患有重度感音神经性听力损失，其PTA超过120分贝听力级。通过基础声音识别评估功能性听力。使用针对听力受损儿童早期交流技能量表的结构化观察来评估儿童使用助听器或人工耳蜗时的交流能力。人工耳蜗使用者以及A组和B组在声音识别水平上的基础听觉功能随时间有所改善。C组几乎没有改善。在佩戴设备6个月后及之后的评估中，所有组（无论是使用助听器还是人工耳蜗）在听力受损儿童早期交流技能量表上的表现均接近其年龄的平均水平。
