I am going to play devils advocate now, do you think it could possibly be that people become more intolerant of noise as they age?
We have five children, the noise at times was loud, both inside and out. As parents we were capable of distinguishing between general shouting and screaming and a scream/shout of pain and/or anguish.
When it is your own child/children you can tell the difference in their screams, but not when it is someone else's. If your child is out of your earshot, it would be someone else who came to their aid in a real emergency - but if they are ignoring the screams because the mother could be annoyed at them for "upsetting" the child, they would get no help.
When we were young, any adult seeing us do something dangerous or anti-social would feel a responsibility, and be quick to comment, but now they don't dare to for fear of being accused of "harassing" or "giving verbal abuse to" children.
