Ultrasound danger?

Commented on January 01, 2014

I've read different things about the danger of ultrasounds/sonograms. Linked to autism, hearing damage, negative side effects from the heat...

Of course, I wouldn't want to do anything to harm my baby, but it's so hard to distinguish what's a legit concern and what is internet alarm-ism.

Thoughts? Experience positive or negative?

Autism: Claiming autism seems to be the adult version of claiming that Mountain Dew will reduce your sperm count. It's a bullshit claim to the cause of a real problem and it is wildly disrespectful to those families and individuals who suffer from it. I'll reverse this stance if given even an ounce of real plausibility. Until then, for shame internet.

Hearing Damage: Damage to the ears are caused by the intensity (read: loudness) of a wave and not its frequency. To do damage I reckon you would need an ultrasound somewhere in the range for 120+ decibels. I can't say I know what a standard fetus viewing ultrasounds runs at, but I would be surprised if it came even close to that threshold.

Negative Side Effects from Heat: As per Wikipedia ultrasounds are apparently kept under 1 watt per square centimeter in order to avoid any heating of the object being observed.

Speaking of Wikipedia, read the first two sentences of the above linked ultrasound article. It's sound. That's all it is. The only thing "special" about it is that it is above human hearing.

Both of my kids were ultra sounded in the womb. They seem pretty smart and normal, no other way for me to gauge this.
