Team led by Japanese researchers reveals best way to put crying baby to sleep:
The evidence-based soothing strategy was derived from experiments carried out in Japan and Italy, which were analyzed and published in the journal Current Biology on Tuesday.
[Senior author Kumi] Kuroda and colleagues wanted to explore this further in humans, and to compare the effect against other comforting behaviors such as rocking in one spot.
They recruited 21 mother-baby pairs aged 0-7 months, and tested them under four conditions: carrying while moving, held still by their sitting mothers, lying in a still crib, or lying in a rocking cot.
Crying decreased and heart rates slowed within 30 seconds when infants were transported. There was a similar effect when they were rocked, but not when held motionless.
[...] This suggested that, contrary to assumptions, maternal holding was insufficient to calm a child, and the transport response was an important factor.
Next, they looked at the impact of carrying infants for five minutes, finding that the activity put 46 percent of them to sleep, and an additional 18 percent fell asleep in the minute after.
This showed that not only did carrying stop crying, it also promoted sleep.
But there was a wrinkle: when infants were put to bed, more than one-third became alert within 20 seconds.
Electrocardiogram readings showed the babies' heart rates rose the second they were detached from their mother's bodies.
However, when the babies were asleep for a longer period of time before being put down, they were less likely to awaken.
Kuroda said she found this surprising, as she had assumed other factors like the way they were placed in bed or their posture would play a role, but this was not the case.

...you can only do so much of this: if you do it EVERY time a baby cries, you modify it's behaviour to cry EVERY time.
Sometimes you just gotta let little Jimmy cry and cry and cry: he cries himself to sleep and maybe another time and then they sleep on their own.
Coddle them and you've got a nightmare in the making.
Walk around on tiptoe all the time so the baby wakes up at EVERY noise; nightmare in the making.
Form a routine (like they won't sleep without both mom and dad singing to them) and ....nightmare in the making (like when one of you has to work instead of singing)....
Some, yes. All the time...... nightmare in the making...
But yes, movement is best: rocking, walking, driving, washing machine (like Runaway said). But sometimes you just gotta let them scream it out.

I wonder how much good or bad came from my early childhood featuring: steady din of a nearby Interstate, planes flying overhead, and the occasional loud car.
I remember being about 4 and asking my Dad about the loud cars. "That's teenagers with hot rods" he said. By then though, I think the original hot-rod era was long gone, but my Dad still called them that. They were most likely "muscle cars". OTOH, the planes man, I went through a phase where they scared the shit out of me. I really had to get used to that, and thunder. Then once you get used to it, you actually like it. We went to air shows. Loved it. Thunderstorms make me nostalgic now. It's interesting how we get shaped to our environment and then the higher level functions kick in: Loud cars? Hate 'em. You're a douche with that motor, son. Get a muffler.
Appended to the end of comments you post. Max: 120 chars.

A few years ago after some idjit wrote off my car by slamming into it while parked outside my place, I had to borrow my partner's parents' car, a Subaru WRX, so we could get around to various car yards to find a replacement. 1/10 - would not recommend. That low-frequency muffler throb gave me a serious headache after a couple of hours (and grouchy mood to go with it).
