基于GB 9068—88浅谈空调产品噪声测试思路
Discussion on testing approach for noise of air conditioning products based on standard GB 9068-88
摘要：
基于对GB 9068—88《采暖通风与空气调节设备噪声声功率级的测定工程法》的分析,结合行业内噪声测试现状,从噪声评价指标、背景噪声修正值、背景噪声限定值、机组安装方式、反射物5个方面指出现行标准的局限,并提出了后续改进建议。

Abstract：
This paper analyses the Chinese standard GB 9068-88 “Determination of sound power levels for noise emitted by heating, ventilation and air conditioning equipments—Engineering method” and examines current industry practices in noise testing. The study identifies limitations in existing standards regarding five key aspects: noise assessment parameters, background noise correction values, background noise limits, equipment installation methods, and reflectors. Improvement suggestions are then proposed to address these limitations.
