This review article summarizes the effects of sensorineural hearing loss on the recognition of amplified speech, both for speech presented in quiet and in a noise background. Some hypotheses are presented regarding the underlying damage in the cochlea that leads to the deficits in speech recognition for hearing losses of various configurations. For severe hearing losses in the high frequencies, amplification is often ineffective. While the existing data also suggest that sensorineural hearing loss can lead to poor frequency resolution, which leads to problems understanding speech in noise, the frequency resolution of the cochlear implant is usually even poorer. Therefore a strategy of preserving low-frequency residual hearing combined with electrical stimulation for the higher frequencies is an attractive solution for patients with severe high-frequency hearing loss.
这篇综述文章总结了感音神经性听力损失对放大语音识别的影响，包括在安静环境和噪声背景下呈现的语音。文中提出了一些关于耳蜗潜在损伤的假设，这些损伤导致了各种类型听力损失患者在语音识别方面的缺陷。对于高频严重听力损失，放大通常无效。虽然现有数据也表明感音神经性听力损失会导致频率分辨率差，进而导致在噪声中理解语音出现问题，但人工耳蜗的频率分辨率通常更差。因此，对于严重高频听力损失患者，保留低频残余听力并结合高频电刺激的策略是一种有吸引力的解决方案。
