I sometimes walk around with a little transistor radio just like this one in my jacket pocket, or I carry it in the mesh side-pocket of my backpack when I'm cycling. It's tuned to CBC AM, usually, what fills the NPR niche here. I don't like wearing ear buds, and much prefer this retro means of listening to stuff. I'm aware of others as I pass, so I keep the volume low, at a normal human speaking level so as not to disturb their reverie or other level of consciousness. But here's the thing: any motorized vehicle going past completely drowns out the radio. Forget diesel engines and motorcycles and other obviously offensively noisy machines. Even a Corolla drowns it out. The tires on the road are noisy.
If I blared the radio as loud as needed to keep it heard, it would be shouting. People would stare at me for A, being odd, and B, for being noisy. Car noise? Fine, apparently.
Have you ever been somewhere so quiet you can hear your blood pumping? People once heard that all the time. Now it would drive them mad. Me? I would I turn on CBC. Keeps you sane.
