一种基于聚类分析的护听器筛选分类方法

A Sorting Method of Hearing Protectors Based on Cluster Analysis

对于长期佩戴护听器的人员,护听器不仅要求隔声效果好,而且舒适性也要很好。这样在考虑不同噪声频段和多技术参数的情况下,利用聚类理论对噪声护听器的多技术参数(噪声单值评价值、高频衰减值、中频衰减值、低频衰减值、加紧力、重量等)进行筛选分类研究,对于护听器的多参数综合选择具有重要意义。

Hearing protection for the people who are always working in noisy environment is very important. These people usually wear in anti-noise hearing protectors, which must have good sound insulation performance as well as good hearing comfort. In this paper, considering different frequency hands of the noise, a sorting method based on cluster analysis theory was used to study the multi-technical parameters of the hearing protectors, such as single value of noise evaluation, high frequency attenuation value, medium frequency attenuation value, low frequency attenuation value, tightening force, weight, etc. The hearing protector＇ s comfort index was analyzed. To improve hearing protector＇ s comfort, the subjective evaluation of bipolar scale was studied. This work has provided a technical support for hearing protection of the workers in noisy environment.
