ActiveReciprocating internal combustion engines—Measurement of sound power level using sound pressure—Part 4: Survey method for use in situ
往复式内燃机 声压法声功率级的测定 第4部分:现场测量简易法
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 in situ, without requiring a specialized acoustic environment. It is applied for on-site noise assessment of engines in their operational locations, such as in power plants, marine vessels, or industrial machinery installations. The method enables practical noise level verification and comparison against regulatory limits or manufacturer specifications during field testing.
