Coming Soon đ At the beginning of April, youâll be
introduced to a brand-new GoComics! See more information here. Subscribers, check your

Letâs see. 55 mph is about 81 feet per second. Guess about 400 feet for a city block. I can hear the truck about one block away. 400 divided by 81, about 5 seconds. More or less. Of course, I also have to state: âyour mileage may varyâ.
Trick question. The Doppler effect does not increase as the truck recedes, itâs constant given the speed. What makes it unrecognizable is distance not Doppler.
As I observe the Doppler effect, as the classic case of the receding train whistle, I noticed that the effect does change with distance. The pitch shift is large at first, decreasing in amount and rate of change as the train moves farther away. However, the effect on a melody will be negligible, because all pitches will shift by roughly the same amount. The ratios between pitches will not change enough to render the melody unrecognizable before the sound fades away in the distance.
Doppler would change the key (lower the pitch), but have no other effect. Background noise has far more effect than anything. On a windless prairie, the tune would be recognizable at a mile, in traffic-filled city it will be lost in a couple of corners.
Badly-written question. As anyone who has heard a musical truck go by should know, the Doppler effect might change the perceived pitch slightly, but it wonât make the tune unrecognizable. The tune is recognizable until the truck is far enough away that you canât hear it.
Ice cream Trucks in my time had a string of bells. No recorded songs. Made kids salivate for popsicles & ice cream. Then beg a nickel or dime from parents.
Mae West said too much of a good thing can be wonderful, and Robert Heinlein (and Mick Jagger, and Seal, and Ayn Rand, and half the world, appropriately) said anything worth doing is worth overdoing. I love it. But then Sting wrote the song âMessage in a Bottleâ with the closing phrase âsending out an SOSâ repeated over and over and over until you realize that there most certainly CAN be too much of a good thing, and that a perfectly good riff can most certainly be overdone, and GOOD GOD, WILL THIS FORMERLY GOOD NOW DREADFUL SONG NEVER END? To this day, I donât know what their producer was thinking.
Itâs a nice way to look at the end of summer. A quarter-year of it is just fantastic. Shoot, a half-year of it, depending on your latitude. And maybe itâs good all year âround, if thatâs your thing, but I donât know if it could be my thing. Make no mistake, fall comes too soon for me every year, but it needs to come, or else Iâd either summer myself into burnout or, worse, into complacency. And while summer might end too soon, better too soon than too late. Iâd rather suffer through sleet than forget how to appreciate sunny and 70s.
Although thatâs where the musical analogy ends, because it seems more often than not, on the kind of radio stations or â deal with it, boomers â grocery store soundtracks that play âMessage in a Bottle,â the next song is something by the band Journey, which is like summer ending and being followed not by a chill but by The Plague.

Does every ice cream truck plays that? âTurkey in The Strawâ? The one in our neighborhood certainly does!

I donât know about the Doppler effect, but it took about 60 years for the sound to fade to me. But then I am going deaf so,âŠ.

Does the Doppler Effect matter if you missed your last chance at ice cream?

Why is the ice cream truck doing 55 in a residential area? Or do they live on the freeway?

For many parents, the thing that takes the sting out of the last day of summer is that itâs the last day of summer.

Much would depend on how fast you are going to catch up with it.

Jeff Mallett must live up north. Where I live, we have ice-cream trucks all year.

I love the fact that this strip not only makes me chuckle but ponder, learn and wonder too.

This one reminds me of a Q&A I found online a while back:
If you have four pencils and seven apples, how many pancakes will fit on the roof?
Purple, because aliens donât wear hats.
