Benasich will also be the first to say that you don’t have to have this exact sound machine. Is there a healthier alternative to white noises, and other traditional sound machines?ĭr. In tens of milliseconds, short patterns of sound “tickle the brain” and are complex, changing over time, she says. “Womb sounds have lots of variation and an underlayer and overlayer of sounds - babies begin to learn about speech sounds in their last trimester, when they are hearing muffled but distinct lower frequency sounds that help the brain set up those linguistic networks,” Dr. Or, you might find yourself in a more realistic womb setting than the “perfect” womb, in which you can hear additional rustling or jostling that isn’t as repetitive as other products might have. But what you’ll also notice if you listen closely, are those cues that differentiate it from other sound machines, such as a twig cracking in the nature scene. If you listen to RAPT’s Smarter Sleep sound machine, you will hear noises that seem typical of any sound machine, like a nature scene with leaves and a pleasant breeze. “Our goal was to take the sound machine, which is typically just used to promote sleep, and add an enriched supportive auditory environment that is more beneficial for a baby’s development,” Benasich adds. “It analyzes the speech stream and segments it this word begins and ends here, this sound belongs to this other sound.” The Smarter Sleep Machine is different from your average white noise machine because it uses subtle but structured acoustic cues built into the soundtrack that stimulates an infant’s efforts to identify sound to build those language networks. “Lots of parents don’t know that when their babies are sleeping, their brains are very busy…they are setting up these networks and listening for specific sounds that the brain analyzes statistically,” she says. Solomon Endowed Chair in Developmental Cognitive Neuroscience at Rutgers University, and the director of the Infancy Studies Laboratory at the Center for Molecular & Behavioral Neuroscience, explains the need for a smarter sound machine. Building the Smarter Sound Machineīenasich, who is the Elizabeth H. The Smarter Sleep sound machine is designed not to just drown out noisy dogs and siblings in the background during nap time, but to encourage cognitive development in the sleeping baby’s brain. April Benasich, who offers a “smart” sound machine for babies and kids, says it might be time to ask different questions entirely in order to find the most optimal product for your baby’s development. What’s going to drown out all that background noise? What sounds most like the womb? What will give us just a tiny bit more shut-eye as brand new parents? All valid questions, and key considerations when they shop for this product.īut neuroscientist and co-founder of RAPT Ventures Inc., Dr. In pregnancy or early days after a baby’s birth, parents often find themselves shopping for a sound machine for their nursery.
