Could you please provide me the reference for the attached noise correction table for the different pipe and wall thickness and the reference for the equation to determine noise correction.Unknownhttps://www.blogger.com/profile/13871995150613278320noreply@blogger.comtag:blogger.com,1999:blog-8968604820003269863.post-61092228007519083492009-06-08T06:59:14.370-07:002009-06-08T06:59:14.370-07:00The noise correction factor contain Sound Power Le...The noise correction factor contain Sound Power Level (PWL) attenuation and correction from dB to dBA. Therefore the PWL generated at source minus the noise correction factor (attenuation plus correction) lead to noise level in dBA.Webwormhttps://www.blogger.com/profile/11991072858350648438noreply@blogger.comtag:blogger.com,1999:blog-8968604820003269863.post-61109684394158623062009-06-08T06:49:08.379-07:002009-06-08T06:49:08.379-07:00Hi,
