I've been doing noise assessments for HUD-funded projects by hand for about a year now. I have not been willing to put out the effort to create a "fill in the blank" Excel spreadsheet to automatically calculate and enter information because of the formula complexity. Does anybody have an Excel spreadsheet that could serve this purpose? I find it hard to believe that HUD has not created a form like this yet, but I have not found it on huduser, hudclips or the main HUD website.
