摘要
目的 :针对环境噪声实时监测的重要性,研制一种便携式单兵噪声监测仪。方法 :在常用噪声分贝仪基础上进行改进,仪器主要由噪声探测球、主机、附件3个部分组成。其中,主机包括噪声探测、计算、分析以及报警4个功能部分;附件主要有电池、耳机、袖带式主机袋等。结果:该仪器实现了单兵作业环境噪声暴露的检测、处理、评估、报警及信息记录与存储,经使用,官兵耳鸣、听力减退的发生率显著下降。结论:该噪声监测仪整体设计新颖,质量轻,体积小,携带、使用方便,适合在多种军事作业噪声环境下使用。
Objective To design a portable device of noise exposure monitoring. Methods The device was developed from the common noise decibel instrument, which was composed of a noise detection sphere, a main device and accessories.The main device consisted of four components for noise detection, computation, analysis and alarming. The accessories included batteries, earphone, cuff-like device bag and etc. Results The device could be used for the detection, treatment,evaluation, alarming of individual noise exposure as well as information recording and storage, and could make the incidence rate of tinnitus and hypoacusis decreased greatly. Conclusion The device gains advantages in design, weight,volume, portability and operation, and can be applied in multi military operation environments.
