Because we're bloody daft
This is a question I wondered about also.... with my childen and after contemplation and pondering I know for mysef from my own usage ...that when I used a normal voie the babies made no reation as if they did not know they wetre being talked to and when I raised the pitch and tone..it got the babies attention...as if they now new this was being diected at thm and they were more inclined to give vocal as well as physical reactions such as cooing... smiling..flailing of limbs in acknoledgement of theirability to refognize this talk to them and differentiate the normal tones as being directed to others.....Does that make sense to you???
Two possibilities explanations occurred to me.1. Physical: because of their small size the baby's tiny eardrums resonate at a high frequency, so high frequency sounds are louder to the baby than low frequencies, i.e. they are comparatively deaf to low frequencies so are more likely to respond to high pitched sound.2. Evolutionary: babies who pay attention to those with high voices, females, are more likely be fed and survive than babies who prefer the low voices of males, (who do not lactate !).

Ultra Hearing FetusThe sounds the fetus hears in the uterus during ultrasound procedures. Dr. Mustapha Fatemi, a medical engineer at the Mayo Foundation's Ultrasound Research Laboratory in Rochester, Minnesota, and his team of researchers recently discovered that fetuses can actually hear ultrasound scans, which were previously thought to be inaudible. Fatemi originally became interested in the issue after hearing that fetuses often act up during ultrasound exams.
