sclerosis, I have spent long periods of time convalescing. It was in the solitude and stillness of my sickroom that God's voice became evident in that enforced quiet. Is that a blessing? Yes, it believe it has been. I have drawn closer to my Redeemer despite and even because of my illness and vulnerability.
I think a tool of Satan has been business, frenetic activity and noise in people's lives to block out the voice God. Quietude is sacred. Sometimes achieving it must be deliberately sought by people.
In the 15th Century Christian classic book The Imitation of Christ by Thomas a Kempis (1380-1471) he wrote:
"I will listen to what the Lord God will say to me. Blessed is the soul that listens when the Lord speaks to it  and receives consoling words from His lips."
"Blessed are the ears that are attuned to God's quiet whisper  and ignore the world's raucous sounds. Blessed, indeed, are the ears that disregard the noises outside and wholly attend to the voice teaching truth within."
|Thomas a Kempis|
God says in the Psalms to "Be still, and know that I am God." Jesus went into solitude of the wilderness to pray and spend time with the God the Father.
Quietude is an important aspect to the Christians prayer life. And as Thomas a Kempis alluded to we must guard what comes in to us by our eyes and ears that may corrupt our interior spiritual life or divert our attention to God.
Guard your quiet moments with God and purity of heart.
