My nephew and his friends picked my daughter and me up from the airport. For the next three hours, he had the radio cranked to ten.

・Oxford English Dictionary: A loud, unpleasant, and prolonged noise.: the fans made an awful din
・Collins Dictionary: A din is a very loud and unpleasant noise that lasts for some time.: They tried to make themselves heard over the din of the crowd. ・Cambridge English Dictionary: a loud, unpleasant confused noise that lasts for a long time: I had to shout to make myself heard above the din.
なるほど、"ding-dong" を連想しましたが、おそらく共通の語源でしょうね。
