​Resturants should push for more soundproofing in their establishments to promote conversation instead of just loud crowd background noise which makes table conversations impossible.

Of course it costs money to hire a sound consultant which most restaurants would rather not spend a dime on. However simple things can be done to reduce noise levels such as soft materials on walls and floors instead of hard wood or concrete. Also depending on space they could also use dividers like in pandemic days to block sound as well.
