If one is staying in an Old Age Home and they blow the shofar via a microphone, should he also place earplugs on his ears?
A. The same as above applies, yet one may cover the ears with a blanket.
However, one must procure and arrange before Yom Tov via Bikur Cholim or any other Frum help organization available to have a proper Shofar Blower come to his place at the institution or at home to blow the shofar correctly.
