Blasting sound out of your vehicle into a residential area for hours just because you want to sell something is selfish.

So is defending the behavior and imposing it on everyone around you just because it's sometimes convenient for you to walk 10 meters for some ice cream once a month.

Like TFA says, we have to decide as a society what kind of noise we think is worthwhile. The sound of kids playing seems essential for a culture to stay friendly to family development.

But broadcasting an advertisement jingle to neighborhoods because you want to make money, perhaps not.

You are focusing on the driver, but what about the patrons. Is one selfish person listening to sound for a minute enough to to prevent 10 kids from being happy? 100? 1000?

Yeah, did you even think of the children?

Would the kids not be happy if the truck was not constantly playing music?

Ice cream trucks are awesome. I have stopped wfh zoom meetings due to Mister Softee coming by and wanting to grab an ice cream. The surprise and delight of a treat when totally unexpected is wonderful. No one complained.

I miss Mr Softee too!

So what about the sound of your car going by my house every morning? That's really the irony, everyone is complaining about all sorts of noise, but the worst noise in urban environments, the constant traffic & car noise, is somehow sacrosanct.

No, doing so is the equivalent of using Adblocker.

Isolating yourself from the sound via one of various available methods would be analogous to using Adblock.
