Baby sleep sounds

Soothing sounds to help your little one sleep peacefully

Calma is an elegant, easy-to-use baby sleep sounds app offering consistent white noise, gentle rain, and womb-like low frequencies. Quickly calm a crying infant, establish a comforting naptime routine, and build soundscapes that mask sudden noises.

Mask disturbing sounds

Babies are easily startled by sudden household noises. Continuous, rhythmic white noise from Calma creates an acoustic blanket that helps babies sleep longer.

Mimic the womb

The womb was a loud, whooshing space. Low-frequency brown noise, heartbeats, and deep water sounds remind your newborn of that safe environment.

Customizable mix

Every baby is different. With Calma, easily mix a humming fan with gentle rain to find the exact frequency that instantly calms your baby.

FAQ

Baby sleep sounds FAQ

Is white noise safe for babies?

Yes, white noise is generally considered very safe and effective for babies, provided that the volume is kept at a comfortable, conversational level (around 50-60 decibels) and the device is placed a safe distance from the crib.

Which color of noise is best for newborns?

Many babies respond well to standard white noise, but pink noise and brown noise (which emphasize deeper, lower frequencies) can also be perfect for simulating the muffled sounds of the womb.

Does Calma require internet to play offline?

Calma works offline. Once you have the app installed, you don't need an active internet connection to play your baby's favorite sleep mix.
