Stranded whales and autism in children may both be linked to use of ultra sound

Two quick questions: If sonar beams can kill fully-developed dolphins, what effect, then, do they have on the developing brains of in-utero embryos and fetuses? And why is this never discussed or debated or mentioned on TV broadcasts like the ones last week that reported the CDC’s latest and quite disastrous findings?

Getting back to those embryos and fetuses, Rodgers explains that an ultrasound used in fetal imaging emits short pulses of high-frequency sound waves that reflect off the tissues of the fetus, and the return echoes are converted into images. In addition to vibration, ultrasound waves can cause heating of the tissue and bone.”

When the transducer from the ultrasound is positioned over the part of the fetus the operator is trying to visualize,” she continues, “the fetus may be feeling vibrations, heat or both.”

Rodgers then cites a warning the Food and Drug Administration issued in 2004: “…even at low levels, [ultrasound] laboratory studies have shown it can have…”jarring vibrations” – one study compared the noise to a subway coming into a station – “and a rise in temperature.”
