Thank you for your contributions. It seems that you may have added public domain content to one or more Wikipedia articles, such as Sound level meter. You are welcome to import appropriate public domain content to articles, but in order to meet the Wikipedia guideline on plagiarism, such content must be fully attributed. This requires not only acknowledging the source, but acknowledging that the source is copied. There are several methods to do this described at Plagiarism, including the usage of an attribution template. Please make sure that any public domain content you have already imported is fully attributed. Thank you. — Diannaa 🍁 (talk) 00:19, 1 February 2017 (UTC)

I have removed your edits to Aircraft noise. The text and image you added to the article added nothing of value to the topic and seemed to be intended just to promote NIOSH and its website. You probably should review WP:COI before editing more articles. - Ahunt (talk) 00:40, 28 June 2018 (UTC)

Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Airbus A320 family, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. Thank you. McSly (talk) 19:00, 14 July 2018 (UTC)

cabin noise
Hi, perhaps it would be best to avoid adding large paragraphs in airliner articles to avoid WP:undue weight and add one or two sentences to Aircraft_noise instead, where there is already various sources. Also, it is best to avoid going in too much intricate details. Bye,--Marc Lacoste (talk) 07:45, 15 July 2018 (UTC)
