| Abstract: | 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. |
