摘要
从声压和声强两个角度研究了背景噪声和声反射对噪声测量的影响,并探讨了减小影响、提高测量精度的措施。在保证精度的前提下找到可应用于普通实验室条件乃至工作现场的噪声测试方法。
Measurement conditions have a significant effect in noise testing. Both background noise and sound reflection will inevitably cause measurement error. Aiming to make noise testing more reliable and economical, we analyze respectively how they affect the testing in the sense of sound pressure and sound intensity. And we further study the corresponding measures to reduce their effects. Some personal viewpoints are also brought forward in this paper.
