本文概要地阐述了机器噪声测定的基本理论与方法。着重引用实验数据,通过理论分析,论述了在声场条件较差的试验室,对中小功率内燃机进行噪声测定的可行性和测定值的可信性。
This article briefly describes the basic theory and method of machine noise measurement. Emphasis is put on the experimental data. Through theoretical analysis, the feasibility of measuring the noise of small and medium-power internal combustion engines and the reliability of measured values are discussed in the laboratory with poor sound field conditions.
