Chana was the first to introduce the idea of davening quietly, as she saw the need to prioritize the Kavana. The story of the Husyatener Rebbe has various versions. What I related is the version I heard from Rabbi Feder; from Rabbi N. T. I heard that it was the kever of the Orach Chayim and that many people had joined together in Prayer (after undertaking to build Mikvaos all over Eretz Yisroel) and the Prayer lasted about two hours, not twenty four as I indicated.
