Why These Sounds Work

The science, the sound, and the stillness underneath it all.

At New World Baby, every audio journey is made with care, not only in the words and music you hear, but in the subtle sounds beneath it. These frequencies and soundscapes are designed to support your nervous system, your baby’s development, and the bond between you.

Here’s what we use, and why.

🎵 Solfeggio Frequencies

Solfeggio tones are specific musical pitches that have been used in sacred music for centuries. Some believe they carry balancing or healing properties, and while research is still emerging, many people report feeling more calm, safe, and connected when listening.

We use the following tones in different audio journeys:

174 Hz – Safety & physical comfort
396 Hz – Letting go of fear and guilt
417 Hz – Encouraging emotional release & change
432 Hz – Natural harmony with Earth’s vibration
528 Hz – Love, healing, and inner restoration
639 Hz – Emotional connection and bonding
963 Hz – Inner wisdom, awareness, and intuition

🎧 These tones are embedded subtly in the background, you may not hear them, but your body does.

Binaural Beats

Binaural beats are created when two slightly different tones play in each ear. Your brain responds by syncing into the rhythm of the difference, gently guiding you into states like calm, creativity, or restful alertness.

We use these low, safe frequencies to support:

Theta (4–7 Hz): meditation, deep rest, and connection
Alpha (8–13 Hz): relaxed wakefulness and focus
Delta (1–4 Hz): deep sleep and regeneration

Binaural beats are most effective with headphones, as the tones need to reach each ear separately.

Nature Sounds

Water, birdsong, wind, heartbeat… these aren’t just aesthetic choices. Natural soundscapes are proven to reduce stress, support emotional balance, and signal safety to the nervous system.

Research shows:

Water sounds promote calm and tranquility
Birdsong improves mood and reduces tension
Heartbeats offer your baby a familiar, womb-like rhythm

Your body instinctively recognizes these cues as safe, helping you shift out of stress and into being relaxed.

Theta Waves

Theta waves are slow brainwaves that occur during dreaming, deep meditation, and emotional processing. They’re associated with creativity, connection, and inner calm.

We use pure theta frequencies (4–7 Hz) in some audio tracks to gently help you:

Drift into rest
Reconnect with your intuition
Anchor your body and baby in stillness

Do These Really Work?

Science is still catching up to what many mothers already know: that sound has the power to shift how we feel. While not every claim has been fully proven, early research and personal experiences show that these elements can reduce stress, increase focus, and support emotional well-being.

And for your baby, these natural soundscapes may become the first language of safety, calm, and love.
