Silencing mobile devices is a crucial aspect of concert etiquette that is often emphasized to ensure an enjoyable experience for both performers and audience members. The presence of ringing phones or notifications can disrupt the performance and distract both the musicians and those watching.

This practice contributes to the overall atmosphere of the concert, fostering a more focused and engaged environment.
