The true meaning of that the famous painting

I heard that Edvard Munch’s famous painting ‘The Scream’ means that the person standing in the center is not shouting, but “closing his ears as he hears a shout.”

I referred to a strange conversation history of my son and Google Assistant.

絵画『ムンクの叫び』は、中央の人が叫んでいるのではなく、「叫び声が聞こえるので耳を塞いでいる」のだそうです。
