AbolishedReciprocating internal combustion engines—Measurement of sound power levels using sound pressure—Part 4:Survey method using a reference sound source
往复式内燃机 声压法声功率级的测定 第4部分：使用标准声源简易法
Application Summary AI generated
This standard specifies a survey method for measuring the sound power level of reciprocating internal combustion engines using sound pressure with a reference sound source. It is applied in industrial settings for engine manufacturing, quality control, and noise assessment, particularly when a simplified, less precise measurement is acceptable for compliance or comparison purposes. The method is suitable for field testing of engines in applications such as automotive, marine, and power generation.
