Shabbos Bulletin Parshas Pinchas 5778

When making the berachos over the Torah upon receiving an aliyah, care must be taken to make the berachah loudly. If less than 9 adult males hear the berachah, it is very questionable if it is valid. If at least 9 adult males hear the berachah, everyone may respond–together with them—”baruch HaShem hamevorach…”

If less than 9 heard, no one may respond “baruch HaShem…” nor may anyone answer “amein.”
