Practical solutions are needed here, some at the communal level and some at the individual level.
At the communal level:
Shul layout plays a role. If everyone is fairly close to the Bima (where the Torah is read from), they will focus on the actual reading of the Torah.
Our shul eliminated “mishebeirach”s (potentially long prayers for each person called to the Torah with expected donations from them) and uses pledge cards instead.
Individual level: Sit as close to the Prayer Leader and / or Bima as practical.
