Incubeats is committed to advancing neonatal care through collaborative clinical research and responsible scientific development.

The project is grounded in a growing body of scientific literature exploring the role of maternal voice, and maternal heartbeat stimulation in neonatal intensive care environments.

​

A growing multicenter clinical initiative

​

Incubeats is currently collaborating with hospitals and neonatal care teams preparing a multicenter clinical initiative evaluating personalized maternal acoustic exposure within neonatal intensive care environments.

This growing institutional engagement reflects increasing interest in:

• developmental neonatal care

• family-centered NICU practices

• non-invasive supportive interventions

• individualized sensory support

• developmentally supportive NICU environments

The initiative aims to evaluate:

• feasibility within NICU settings

• integration into clinical workflows

• caregiver and parental acceptance

• implementation within developmental care practices

Incubeats is being developed collaboratively with clinicians and healthcare institutions committed to responsible neonatal innovation.

​

Scientific background

An increasing number of clinical studies have explored maternal voice exposure, maternal heartbeat stimulation, and maternal acoustic interventions in premature newborns hospitalized in NICUs.

Published research has reported associations with:

• physiological stability

• neonatal comfort

• feeding-related outcomes

• parental wellbeing

• developmental care support

• auditory and neurodevelopmental processes

Incubeats does not claim to independently produce these outcomes. However, the project is informed by and aligned with this evolving scientific field.

Comfort, stress, pain, and physiological stability

Several randomized and observational studies have explored the role of maternal acoustic stimulation in supporting neonatal comfort and physiological regulation during NICU hospitalization.

Reported findings include:

• reduced procedural pain responses

• increased comfort

• improved physiological stability

• lower heart rate during maternal sound exposure

• support for developmentally supportive care practices

 

“Using recorded maternal voices to limit pain in preterm infants undergoing heel lance procedures appeared safe and effective.”
PMID: 28580602 — Chirico et al., 2017

​

“Auditory interventions used during heel lance reduce the pain and increase the comfort of premature infants.”
PMID: 32653359 — Kahraman et al., 2020

 

“Maternal voice and lullabies may effectively reduce pain and enhance physiological stability in preterm infants during aspiration.”
PMID: 40901698 — Mutlu et al., 2025

 

“During exposure to maternal sounds, infants had significantly lower heart rate compared to matched periods of care without exposure.”
PMID: 4312137 — Rand et al., 2014

 

“This study provides preliminary evidence for short-term improvements in the physiological stability of NICU infants using maternal sound stimulation.”
PMID: 22185623 — Doheny et al., 2012

 

“Exposure to low intensity recorded maternal voice has positive effects on preterm infants’ physiologic responses.”
PMID: 27914263 — Sajjadian et al., 2016

​

Neurodevelopment and auditory maturation

​

Emerging research has explored possible associations between maternal sound exposure and early neurodevelopmental processes in premature newborns.

 

Published studies have investigated

• auditory cortical plasticity:

• sensory maturation

• language-related neural pathways

• auditory developmental processing

These findings contribute to growing scientific interest in the role of early sensory environments during neonatal intensive care.

“Increasing exposure to maternal speech via overnight audio recordings was directly linked to maturation of the left arcuate fasciculus, a white matter circuit implicated in life-long language processing.”
PMID: 1673471 — Travis et al., 2025

​

“This study provides evidence for experience-dependent plasticity in the auditory cortex in preterm newborns exposed to authentic recordings of maternal sounds.”
PMC: 4364233 — Webb et al., 2023

 

“Maternal voice may also induce maturation of both cognitive and respiratory control centers of the brain.”
PMID: 36747385 — Zhang et al., 2025

Feeding and physical development

Additional studies have explored associations between maternal acoustic exposure and feeding-related or developmental parameters in premature newborns.

Published research has reported findings related to:

• feeding tolerance

• weight gain

• physical growth parameters

• developmental progression during hospitalization

 

“Results indicated that a recorded maternal voice intervention improved preterm infants’ growth and development, including weight, recumbent length, and head circumference.”
PMID: 36747385 — Zhang et al., 2023

 

“Preterm infants in the intervention group showed a significant increase in weight, recumbent length, and head circumference.”
PMID: 37331833 — Qi et al., 2023

Supporting families and parental wellbeing

Prematurity and neonatal hospitalization also affect parents and caregivers.

Research has explored how maternal voice interventions may contribute to parental emotional wellbeing during NICU hospitalization, including reported associations with reductions in maternal stress, anxiety, and emotional distress.

​

“The intervention of playing maternal recorded voice to preterm infants in incubators was associated with reductions in maternal depression, anxiety, and stress.”
PMID: 36747385 — Zhang et al., 2023

Collaborative neonatal innovation

Incubeats believes that meaningful neonatal innovation must be developed in close collaboration with clinicians, hospitals, researchers, and neonatal care teams.

 

The project continues to engage healthcare institutions interested in advancing more developmentally appropriate and human-centered NICU environments.

Healthcare institutions interested in:

• multicenter collaboration

• developmental care innovation

• NICU implementation initiatives

• research participation

are invited to connect with the Incubeats team.
