UpcomingReciprocating internal combustion engines—Measurement of sound power level using sound pressure—Part 2: Survey method
往复式内燃机 声压法声功率级的测定 第2部分：简易法
Application Summary AI generated
This standard specifies a simplified survey method for measuring the sound power level of reciprocating internal combustion engines using sound pressure. It is applied in industrial settings for engine manufacturers, testing laboratories, and regulatory compliance to assess noise emissions from engines used in vehicles, machinery, and power generation equipment. The method provides a practical approach for field or production-line noise evaluation where high precision is not required.
