近年来国外对噪声的听觉外影响有许多实验研究和现场调查报道。这里仅就下列几个方面作一概述(包括一些简要的历史回顾)。 听神经系统可分主要系统和次要系统。 主要系统:声刺激→听觉器官神经冲动→听神经→听觉中枢(对声音的综合分析和理解)。 次要系统:声刺激→听神经分支→一部分到达脑干中产生反射运动的神经细胞;另 In recent years, there are many experimental studies and field investigations on the auditory and foreign influences on noise in foreign countries. Here only an overview of the following aspects (including some brief historical review). Listen to the nervous system can be divided into major systems and minor systems. Main system: acoustic stimulation → auditory organ nerve impulse → auditory nerve → auditory center (comprehensive analysis and understanding of sound). Secondary System: Acoustic Stimulation → Auditory Nerve Branches → Part of Nerve Cells Reached in Brain Stem to Produce Reflection Motion;
