I have heard that the use of feedback with delay - an echo - is very effective in disrupting movements like racist chants in say a sports crowd. It is very confusing to hear yourself with a delay of about one second, as anyone who has tried skyping without headphones has probably experienced first hand.
idea is to try and use this phenomenon on babies. Enter Echocry, a device which detects when a baby is crying, and produces the exact sound captured with a one-second delay. It wouldn't stop a baby from "legitimately" crying, but it might confuse it for some of the fake, attention-seeking cries.
As a plus, if it learns to cope with the confusion, your baby will later in life be able to make skype calls without headphones: unquestionably a strong asset.
||Not bad. But I think a baby should be allowed some fake and attention seeking crying.
||So I suggest only to use this for crybabies, babies that cry all the time. Test it and see what happens.
||The crybaby will quickly figure out that it's a lot more interesting to make sub-1s shrieks and overdub itself, and grow up to become a famous hip-hop artist.
There's a serious dubbing/looping toy niche for the 1-3 year market, I think.
