Marpac LifeSounds 440 Sound Machine for Infants, Babies, Toddlers and Small Children - The Unwind Company

Marpac LifeSounds 440 Sound Machine for Infants (works for any age)- Create a Soothing, Relaxing Atmosphere for your baby, toddler or anyone in need.

Recommended by leading pediatricians to help babies fall asleep faster and stay asleep longer. The LifeSounds sound conditioner was designed to comfort infants and small children with a unique selection of natural sounds. LifeSounds incorporates both digital and synthesized sound technology to create a realistic and soothing assortment. The womb, heartbeat and lullaby selections are peaceful and comforting to infants, providing a secure feeling while masking out unwanted noise. Even irritable or colicky babies are soothed by these LifeSounds. Three other selections (surf, rain and brook) are perfect for children of all ages, making LifeSounds the one sound conditioner that grows with your child to provide calming sounds throughout his or her life.

Sleep Better with LifeSounds
Scientific studies dating back to the early 20th century have proven that children, as well as adults, go to sleep faster and sleep more deeply when exposed to natural environmental sounds. Research also demonstrates the calming effects these sounds can have on irritable and colicky babies. LifeSounds can be a real lifesaver for moms and dads (Grandparents too!)

The LifeSounds 440 is Portable
LifeSounds is small enough that it can be packed in a diaper bag or overnight bag, so it can travel when baby does. It can also operate on batteries (sold separately) to provide soothing "LifeSounds" in the car, motel room...anywhere you go! The optional 60 minute timer, with automatic shut-off, helps conserve batteries when traveling.

Marpac LifeSounds is Very Versatile
LifeSounds can be used to mask street noise, barking dogs, noisy neighbors, air traffic, even a snoring spouse. Take it to work to mask office sounds, conversations and manufacturing noise. The LifeSounds Sound Conditioner is the perfect way to bring peaceful sounds into a noisy world- Regardless of your age!

Over 40 years ago, the founder of Marpac developed the original Sound Screen¨ sound conditioner because he was having trouble sleeping. It worked so well, he made it available to his friends and family and ultimately the world. Today, the Sound Screen¨ is still the most economical, most popular sound conditioner on the market.

Marpac combines American ingenuity and craftsmanship to create lightweight, yet durable sound machine and sound therapy appliances capable of many years of reliable service. The nature sounds and womb sounds effectively mask unwanted noises and create a sense of calm, making it easier for your baby to relax or fall asleep.

We recommend the entire Marpac Sound Therapy or Sound Conditioner line for any restless sleepers, shift workers, infants, children, students, apartment dwellers, office workers (for confidentiality) and others. We offer the complete Marpac line, including International versions with dual voltage options. If you don't see the version you are looking for, please drop us a line at 1-888-486-9463 and we'll get you taken care of ASAP!
