Q. I go every year to blow shofar to people residing in a Old Age institution. It happened a number of times that when I enter a room, the occupant tells me that he already heard the Shofar by listening to someone else who was blowing in an adjacent room. Do I have to blow for him again since after all whoever was blowing on that room probably did not have any intention to be moitzi (make comply) someone in another room?
A. Mishna Berura (589: 17) rules that if one heard the blowing of the shofar from a neighbors house, as there where blowing for the sick, he does not comply, since they likely did not have any intention for others outside that house to be yotze.
However, the situation when blowing in a hospital room is different, since it is common that others in other adjacent rooms may also want to hear the voice of the Shofar.
Chashukei Chemed (Rosh Hashana 29a) and others rule likewise and so is also the opinion of Horav Shlomo Miller Shlit'a.
