aplikasi derau putih terbaik untuk bayi baru lahir tanpa langganan di iPhone
Sereno's Nursery section includes womb, shush, and heartbeat sounds alongside fan and dryer — all synthesized continuously on-device with no looping, no streaming cost, and no subscription.
Jawaban singkat
Sereno's Nursery sounds include womb (a low-frequency rhythmic rumble), a shush (rhythmic modulated pink noise), and heartbeat — three sounds commonly used by caregivers for newborn soothing. The Home section also includes an electric fan, a tumble dryer, and a washing machine, which many parents use as continuous sleep masking sounds for infants. Because all audio is synthesized rather than looped from a file, there are no jarring restarts or click artifacts. Use the sleep pengatur waktu to fade audio out after 15, 30, or 60 minutes once you believe your baby is settled. One Pro purchase buka kuncis all Nursery and Home sounds permanently. Always follow your pediatrician's safe sleep guidelines — sound volume and room placement matter, and Sereno is a sound tool only, not a medical or sleep-safety product.
Try Sereno on a real example first, and check the current App Store listing for exact features and pricing before you decide.
