Welcome to Wikipedia and thank you for your contributions. I am glad to see that you are discussing a topic. However, as a general rule, talk pages such as Talk:Sound are for discussion related to improving the article in specific ways based on reliable sources and the project policies and guidelines, not for general discussion about the topic or unrelated topics, or statements based on your thoughts or feelings. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. Thank you. ~ GB fan 12:56, 12 December 2018 (UTC)

Please do not add promotional material to Wikipedia, as you did to Talk:Light. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you.
