人工耳蜗用于恢复重度耳聋患者的功能性听力。以言语清晰度评分来衡量的成功程度，在患者之间差异很大；少数人几乎没有得到任何好处，而有些人则能够在良好的听力条件下使用电话。利用一种新的神经模型和阈上随机共振原理，我们证明了通过人工耳蜗系统的信息传输速率可以通过添加噪声来全局最大化。如果这些额外的信息可以被大脑利用，那么它将导致更大的语言清晰度，这是很重要的，因为所有人工耳蜗接受者的可理解性都比正常听力的人差，特别是在不利的听力条件下。
Cochlear implants are used to restore functional hearing to people with profound deafness. Success, as measured by speech intelligibility scores, varies greatly amongst patients; a few receive almost no benefit while some are able to use a telephone under favourable listening conditions. Using a novel nerve model and the principles of suprathreshold stochastic resonance, we demonstrate that the rate of information transfer through a cochlear implant system can be globally maximized by the addition of noise. If this additional information could be used by the brain then it would lead to greater speech intelligibility, which is important given that the intelligibility of all cochlear implant recipients is poorer than that of people with normal hearing, particularly in adverse listening conditions.
