"置若罔聞"用英語怎麼說？

“置若罔聞”，漢語成語，意思是放在一邊，好像沒有聽見似的。指不去過問、不理睬（ignore completely，pay no attention to）。與英語習語“turn a deaf ear”意思相近，表示“to ignore someone when they complain or ask for something”。

例句：

過去，他們往往對這種要求置若罔聞。

In the past they've tended to turn a deaf ear to such requests.

他們要求釋放人質的呼籲被置若罔聞。

Their appeals to release the hostages fell on deaf ears.
