Hello, I'm Geardona. An edit that you recently made to Active noise control seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Geardona (talk to me?) 01:46, 14 January 2024 (UTC)
