Most pasken according to the Shulchan Arukh that mundane talk in shul during tefilot is forbidden. With some exceptions: Is mundane speech allowed in shul?.
Is there anywhere a halachic point of view that talking may be permitted, and that it does not have a negative affect on the tefilot? Can members of a shul halachically stop people from talking? Can anyone provide any sources as to why you may be allowed to?
