Regarding questions about the SOUNDS of the BabyPlus Prenatal Education system, I want to give the following information...

Some experts say that a baby’s hearing develops as early as 14 weeks, others say 16-18 weeks. We feel that by the 18th week of gestation a baby’s hearing is fully functional, and that is why you will begin using the BabyPlus at 18 weeks.

During the prenatal months, your child hears many different sounds. What we have learned is that music is wonderful for infants and children post-natally. As methods of prenatal enrichment, however, we believe it is not very effective. Research has shown that the fluid surrounding the baby muffles all but the simplest sounds. Music is too random and complex, and the spoken word is too hard to understand. The baby has no frame of reference for those sounds. That is the amazing idea behind BabyPlus - the sound your child hears all day every day is your heartbeat! Over the course of the sixteen lessons, your baby will hear your heartbeat and the slightly different sound pattern of the BabyPlus, and begin comparing/contrasting those two sounds - learning has begun! Incredible!

The sound level to the baby is strictly controlled for both pitch and volume. Dr. Logan spent many years studying the normal environment of the developing baby, and BabyPlus® is carefully designed to present sounds to the prenatal infant at a very safe but audible level. Normal sounds in a mother's environment--television, loud remarks, traffic--reach the fetus at volumes similar to that of her heartbeat yet the baby still sleeps through it most of the time, even though its brain is monitoring the sound. BabyPlus is designed to produce an external sound of about 105 decibels, which is then reduced by 30-35 decibels as it is filtered through the mother's abdominal wall, reaching the unborn infant at 70-75 decibels, well below the sound level of the mother's blood.

BabyPlus therefore has a scientifically engineered sound ceiling which is always less that the natural sonic environment of the womb. More than 100,000 families worldwide have attested to its safety and effectiveness. Overstimulation does not occur because the sound is so familiar to the developing baby. The tones are natural, and the sound level is safe. Of the 100,000 BabyPlus children born to date, there has never been a case of hearing damage--or any other detrimental effect from the product. Think about it - your baby is not in a sound-proof booth! He or she is hearing so much during the prenatal months - why not use sounds that are scientifically proven and researched???

I know this sounds very "science-y" - but the truth is, the BabyPlus is an unbelievable way of enabling your child to have the ability to learn easily and well throughout his or her life. What parent wouldn't want these benefits?
