Talking about what our parents let us get away with - still happens today. And the obstacles to that.
We still have to pay exorbitant rates for a firearms silencer, plus a Tax Stamp, yet in my locality there is zero - zip - zilch - nada enforcement for large motorcycles with NO muffler, regardless of law. "Loud pipes save lives" might be something to usurp as a motto, maybe? I'm going to start using that old chestnut when it pops up.
Rock bands and bars. The sound is so loud you can sit in the parking lot and name that tune. The bass affect of having your lung tissues resonate seems to be preferred.
Home theatre. Being 63 I've driven up to my own home with the TV on and can determine what program is on by the sound affects. Each has it's unique signature. How loud do you need your TV? Well, at one point I was wearing wireless headphones to listen to it, but no, that was selfish and she who must be obeyed decided they can't be worn anymore. In terms of sound volume it was a no win situation.
Now, at the workplace, I am in a new building and it's a concrete tube with polished floors and very little sound absorption, with the phone "alarm" turned up as high as it will go to force workers to answer it immediately regardless of who they are working with at the counter. I'd love to get a dB reading on that.
And then there's just the sound of passing traffic - since the ringer volume is so high nobody stays in the building for lunch - old or new - as the broadcast horn is directly over the lunchroom table pointing down at YOU. So we sit in our cars for a moment of quiet but in the summer, not happening. You are subject to diesels jake braking, motorcycles, hot rods, pickup trucks with loud/no mufflers, brotrucks with 44 tires which roar as they pass by.
We are presently NO better off than we were. It's not about how our parents so casually ignored our safety, it's about society's freedom to make noise and lots of it.
Do we outlaw fireworks in the Fourth, too? I got a lot of damage early on from that alone. We may "know better" but until the Noise Police start writing tickets it likely won't be any better.
