Hello, I'm Velella. I wanted to let you know that one or more of your recent contributions to Noise pollution have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. ''Please do not cite the same primary piece of research across many articles. It is considered link-spam''  Velella  Velella Talk 21:20, 24 March 2021 (UTC)
