Can You Hear Me?

Can anyone commuting in the subway ever hear the overhead announcements? I often wonder about that as almost everyone has their earphones (some with noise-cancelling features) on all the time. People wore earphones for various reasons but personally, I occasionally put mine on to drown out the noise of passengers talking loudly to each other. If we live our lives muting outside sound and just focusing on our own choice music/podcast/activities, do you think there is room for the voice of God calling you?
