近年来许多生产厂家已开始重视测定产品噪声和研究低噪声产品.为了使测试的结果能作相互比较和提高测试水平,对简单实用的测试标准的了解和掌握是十分重要的.当前一些基层单位已具备简易法测试噪声条件,这种方法虽精度不高,但简便易行,因此可以广泛应用.本文主要介绍简易法的特点,对测试环境的要求,确定测量面的方法和声功率级的计算等.
In recent years, many manufacturers have begun to attach importance to the determination of product noise and low noise products.To make the test results can be compared with each other and improve the level of testing, simple and practical testing standards to understand and grasp is very important.Currently some grassroots units Already has a simple method to test the noise conditions, although this method is not high accuracy, but simple, it can be widely used.This paper mainly introduces the characteristics of the simple method, the requirements of the test environment, to determine the method of measuring the surface and the sound power level Calculation and so on.
