Changes in the sensory environment modify our sensory experience and may result in experience-related or learning-induced reorganization within the central nervous system. Hearing aids change the sensory environment by stimulating a deprived auditory system; therefore, they may be capable of inducing changes within the central auditory system. Examples of studies that have shown hearing aid induced perceptual and/or physiological changes in the adult human auditory system are discussed. Evidence in the perceptual domain is provided by studies that have investigated (a) speech perception, (b) intensity discrimination, and (c) loudness perception. Evidence in the physiological domain is provided by studies that have investigated acoustic reflex thresholds and event-related potentials. Despite the controversy in the literature concerning the rate, extent, and clinical significance of the acclimatization effect, there is irrefutable evidence that the deprived auditory system of some listeners can be modified with hearing aid experience.
感觉环境的变化会改变我们的感觉体验，并可能导致中枢神经系统内与体验相关或学习诱导的重组。助听器通过刺激受损的听觉系统来改变感觉环境；因此，它们可能能够在中枢听觉系统内引发变化。本文将讨论一些研究实例，这些研究表明助听器可在成人人的听觉系统中引起感知和/或生理变化。在感知领域的证据来自于对以下方面进行研究的各项研究：(a)言语感知、(b)强度辨别和(c)响度感知。在生理领域的证据则来自于对听觉反射阈值和事件相关电位进行研究的各项研究。尽管文献中对于适应效应的速率、程度和临床意义存在争议，但有确凿证据表明，一些听力受损者的听觉系统可以通过佩戴助听器的经历得到改善。
