I can easily believe there could be damaging and even lethal magnitudes of sound volumes transmitted to fetuses which are surrounded by amnyotic fluid from ultrasound machines.

+1. I also think it isn't a bad thing to give people a reason to back off of the ultrasounds for sport. Of course certain types of and conditions in pregnancies warrant frequent ultrasounds, but ultrasounds at every appointment just because it is fun for mom to see the baby, or, worse yet, ultrasounds at a non-medical place to get some cool 3-D pictures or find out the sex of the baby early??? A little ridiculous.

If this was to have any legitimacy, they would look at the rates of autism among those who had high exposure. Even then, you would need to rule out other factors (i.e. those issues that necessitated multiple ultrasounds).
I get that people are interested in understanding why this disorder happens so that we can work on prevention, but wild goose chases like this seem to me to be harmful to the cause. Just another vaccine type distraction.

The thing is, you have to be really careful about causation. Older women are considered more at risk for having a child with autism. Because of the concerns around pregnancy and AMA, older moms get more ultrasounds. That doesn't mean ultrasounds lead to autism, it could just mean that older moms are more prone to having a child with autism and they happen to be the population having more ultrasounds.
Either way, I'm glad that the focus on vaccines is starting to wane. That was a huge waste of resources.
