No — managing digital notifications addresses only one of the two primary distraction sources in an open-plan office. Even with perfect notification management, the Irrelevant Speech Effect from intelligible background speech continuously loads the phonological loop and degrades the working memory that deep work requires. Research consistently shows that reading comprehension drops 20–30% and writing quality declines in the presence of intelligible background speech, regardless of the listener’s intent to ignore it. Both digital and acoustic sources must be addressed for deep work to be reliably accessible.
