Earlier quoted context omitted.
Kids yell for extended periods of time. Not all kids, but a large number of them do. If this is a problem it isn't with the kids. Demand better buildings.
Precisely. Architecture and construction can be improved, but kids are always going to yell. And unless you really believe kids have to live in detached housing, the answer is obvious - fix our environment to keep kids from annoying their neighbors.
Your kids, maybe. This isn't a ubiquitous perspective. But, some people don't tell their kids "no" about anything, so...
I'll teach mine to mostly yell in big open spaces, while biking, on a playground, during sports.
