Many people benefit from the steady, soothing sounds of white noise and so do babies. A constant frequency can help maintain sleep in the toughest environments. Babies are sensitive to our bustling worlds, and the many invasive sounds with multiple amplitudes can cause your child to wake. White noise will help mimic the sound that your baby heard in the womb. The authors have created each track to ensure your child has a full sound support during a nap or sleep. The six sounds have a gentle fade in and out to help to customize the volume 10 seconds after you start the sound. This audio book features six frequencies of white noise: *** Warm White Noise *** Cool White Noise *** Water White Noise *** Dreamy White Noise *** Smoothed White Noise *** Cosmic White Noise What you will not hear: This audio book will not surprise you like others; you will not hear any overlying sounds of music or voices embedded in this book. Download our seven-hour audiobook, and choose the sound that best fits your needs. Enjoy!
