ActiveReciprocating internal combustion engines—Measurement of sound power level using sound pressure—Part 1: Engineering method
往复式内燃机 声压法声功率级的测定 第1部分：工程法
Application Summary AI generated
This standard specifies an engineering-grade method for measuring the sound power level of reciprocating internal combustion engines using sound pressure in a semi-reverberant or free-field environment. It is applied in the testing and certification of engines for vehicles, ships, generators, and industrial machinery to ensure compliance with noise emission regulations. The standard is used by manufacturers and testing laboratories to accurately quantify engine noise for product development, quality control, and regulatory approval.
