SonoBirth: Supporting Regulation and Connection in Pregnancy and Birth

How Sound Becomes a Practical Ally in Pregnancy and Birth

In my previous article, Sound Therapy in the Field of Pregnancy and Birth, I spoke about the profound role sound plays in early life. But once people understand its importance, the next question naturally arises:

How do we use sound in a clear, safe, and effective way during pregnancy and birth?

Many parents and practitioners feel instinctively drawn to humming, singing, or using simple sound tools, yet they are unsure how to apply them meaningfully. They want guidance that is grounded and practical; something that translates research into everyday support.

What follows is an overview of the areas where sound becomes a practical resource for regulation, bonding, and birth support, based on both scientific foundations and years of direct involvement in the field. In fact, since 2013, I have been deeply involved in feminine-centred projects alongside my wife Jaguar Yolande, surrounded by birth professionals in a doula training environment that profoundly shaped my understanding of how sound and presence support the natural processes of birth.

1. Sound and Early Regulation: Physiological Foundations

One of the strongest insights from research is that the fetus is not just passively hearing, it is actively processing and learning from sound.
Studies show that:

• Low–mid frequencies travel most easily through the maternal body (Lecanuet et al., 1998)
• The baby recognises music and repeated sound patterns after birth (Partanen et al., 2013)
• Newborn vocalisations already reflect the rhythmic and melodic qualities of the mother’s language (Wermke et al.)

Together, these findings tell us something very practical:
The prenatal sonic environment directly supports the baby’s developing regulatory system.

Practical support

Parents can create a consistent sonic environment, such as a simple hum, tone, or lullaby, repeated during pregnancy.
This gives the baby a familiar acoustic reference that can be used after birth to settle, soothe, or support sleep.

It doesn’t need to be elaborate. What matters is consistency, emotional warmth, and presence.

2. The Most Supportive Sounds Are Often the Simplest

It is true that sound therapy often involves many tools or specific musical choices. However, pregnancy calls for simplicity.

Warm, low-mid frequency sounds match the natural transmission properties of the womb. These include:

• The mother’s voice
• Tibetan-style singing bowls
• Tuning forks between 128–512 Hz
• Soft humming or toning

These sounds are perceived clearly by the baby and have a calming effect on the maternal nervous system as well.

Practical support

• Encourage slow breathing + gentle vocal toning during moments of stress or discomfort.
• Use a single bowl on the feet or hands to support grounding and relaxation.
• Apply a weighted tuning fork to sacral points for down-regulation and spaciousness.

These interventions are subtle yet effective in supporting the body.

3. Sound Helps By Supporting the Nervous System

During labour, women often naturally use sound: low vowels, deep hums, long sighs and exhalations. This is instinctually intelligent.

Research shows that singing and vocalising:

• Reduce cortisol
• Regulate breath
• Enhance vagal tone
• Support emotional coherence
  (Fancourt & Perkins, 2018)

Practical support

• Encouraging mothers to allow their voices to move freely, without restrictions.
• Supporting a low tone (“mmm”, “ooo”) during contractions to release tensions.
• Using simple rhythmic cues to help them stay connected to breath and body.

This approach is about using the voice as a physiological ally, without any aesthetic consideration.

4. Consistency Creates Continuity

One of the most powerful, and often overlooked, aspects of prenatal sound work is continuity.

Babies remember:

• Melodies
• Tones
• Rhythmical patterns they heard repeatedly in the womb.

After birth, these same sounds help them regulate, orient, and bond.

Practical support

• Develop a “womb sound” with the parents: a short phrase, a simple hum, or a gentle melody.
• Repeat it during moments of calm, rest, or connection.
• Use it again after birth to support transitions.

Think of it not as a technique, but rather as a continuity of relationship expressed through sound.

5. Practitioners Need Sound Skills Too

One essential aspect of perinatal sound work is often missed:
The practitioner’s presence is part of the intervention.

Sound is gentle but powerful in the way it travels deeply, very quickly. This means practitioners benefit from:

• Knowing how sound affects their own nervous system
• Learning to use their voice in a grounded, stable way
• Sensing when sound is supportive or when the system needs less stimulation
• Listening as much as offering sound

Regulated practitioners create warm, regulated environments.

This is also why training in this field matters. Not so much to acquire methods to replicate automatically, but to develop clarity, sensitivity, and confidence.

Why SonoBirth Exists

As I worked more deeply with parents, doulas, therapists, and birth professionals, a consistent theme emerged:
People know sound is meaningful, but they often don’t feel equipped to use it competently or effectively.

SonoBirth Training was created to fill that gap.

It brings together:

• Scientific understanding
• Practical voice and sound tools for pregnancy and birth
• Principles of regulation and somatic awareness
• Trauma-sensitive guidelines
• And a grounded, non-dogmatic approach to the inner work sound requires

My intention with SonoBirth is not to teach people to “do more”, but to help them do less with more awareness… to use sound in a way that respects the physiology of birth and the emotional landscape of the family.

A Closing Note

If the previous article introduced the “why”, this piece opens the door to the “how”.
Whether you are a parent, a birth professional, or a sound therapist, sound offers you a direct, human-centred way to support calm, connection, and nervous-system coherence for both mother and baby.

If you feel called to deepen these skills in a structured, grounded way, the SonoBirth Training may offer the framework and confidence you are looking for.
