Capabilities for understanding speech in noise can be assessed by varying the noise
level relative to the level of the signal (or the signal-to-noise ratio).Normal-hearing
individuals can still comprehend sentences when the noise is about 5 dB louder than
the speech.Implant recipients typically show degraded speech recognition when
signal-to-noise ratios are lowered and generally fail to understand speech when the
speech is less then 5 dB louder than the noise.There is thus a difference of 10 dB
between the performance of CI users and normal-hearing persons.
Children with cochlear implants demonstrate significant improvements in closed-set
speech discrimination,enhanced lip-reading,and most obtain some open-set speech
understanding with their devices.Auditory skills appear to be higher when children
are implanted at a younger age but little difference is seen when implanted before
the age of one year compared to before the age of two [Svirsky,M.A.,personal
communication].Children still improve their auditory skills years after implantation,
and more than 75% of them reach substantial open-set recognition after 3 years of
cochlear implantation [Niparko,2004].
Deaf children generally develop slower than normal-hearing peers,especially at
language related skills such as speaking,reading or writing.However,after
receiving a cochlear implant an accelerated development is noticed.Unfortunately
this accelerated development is for a lot of CI-children insufficient to completely
bridge the gap with their normal-hearing peers [Svirsky et al.,2000].

Deaf children are almost never able to attend regular schools and seldom pursue
higher education.In contrast,more and more deaf children with implants are starting
to attend regular schools with some special help.In fact a number of implanted
persons are studying at universities,including two of the test subjects that
participated in the experiments of this thesis.

能力理解讲话的噪音可以评估不同的噪音水平相对水平的信号（或信号噪声比） .正常听力个人仍然可以理解句子时的噪音是5分贝胜于的讲话.植入者通常表现出退化的语音识别时,信噪比率降低,一般不理解时的讲话
讲话是不到5分贝胜于噪音.因此,有差异的10分贝性能之间的开曼用户和正常听力的人.
儿童人工耳蜗植入显示显着改善封闭集讲话歧视,增强唇读,并取得一些最开放的一套讲话了解他们的设备.听觉能力似乎更高当儿童植入的年龄,但差别不大时,被植入前年龄一年前相比两岁[ Svirsky ,马,个人通讯] .儿童仍然改善他们的听觉能力来植入后,超过75 ％的人达到相当开放的承认后,成立3年人工耳蜗植入[ Niparko ,2004 ] .
聋儿一般发展速度慢于正常听力的同行,尤其是在与语言相关的技能,如说话,阅读或书写.然而,在接受人工耳蜗植入一个加速发展的注意.不幸地这是加快发展的很多词儿童不足以完全缩小这一差距的正常听力同行[ Svirsky等.2000 ] .55
聋儿是几乎从来没有能够参加正规学校,很少追求高等教育.与此相反,越来越多的聋儿开始与植入经常参加学校的一些特殊的帮助.事实上,一些植入人在大学学习,其中包括两名测试科目参加实验的这一论断.
