Creating a Calmer Birthing Space: How to Reduce Noise Levels in Delivery Rooms

"Simple changes can make a big difference in the well-being of newborns, mothers, and healthcare teams."


The environment of a delivery room plays a critical role in the well-being of everyone involved. While medical advancements are essential, the focus on creating a soothing and supportive space is just as important. One often-overlooked aspect is noise pollution, which can significantly impact newborns, mothers, and the healthcare team.

Noise in delivery rooms isn't just a minor annoyance; it's a form of energy created by colliding molecules, resulting in pressure variations that our ears perceive as sound. Unlike pleasant or neutral sounds, noise is disorganized and can be physiologically incompatible with the human ear. High noise levels can lead to physical discomfort, psychological distress, and behavioral changes.

This article will explore the findings of a study focused on noise levels within delivery rooms. It will offer practical solutions to mitigate these issues, creating a more calming and therapeutic environment for everyone involved.

Why is Noise Reduction Important in Delivery Rooms?

A recent study investigated the sound pressure levels (SPLs) in delivery rooms at a Brazilian university hospital to identify noise sources. Data was collected over several months using dosimeters to record sound levels and unstructured observation to pinpoint noise origins. The results highlighted some concerning trends.

The study found that average equivalent sound levels (Leq) were 69.6 dBA during vaginal deliveries and 65.4 dBA during cesarean sections. These levels exceed the recommended limits set by regulatory bodies. The primary source of noise was identified as conversations among professionals within the delivery room.

  • Impact on Newborns: Noise can disrupt sleep patterns, increase stress, and potentially affect auditory development. Studies show that premature infants exposed to high noise levels may experience physiological changes, such as increased heart rate and decreased oxygen saturation.
  • Impact on Mothers: Elevated noise levels can increase anxiety and discomfort, hindering relaxation and potentially interfering with the bonding process between mother and child. A calm environment is crucial for a positive birthing experience.
  • Impact on Healthcare Professionals: Constant exposure to high noise levels can lead to stress, fatigue, and decreased concentration, potentially affecting performance and increasing the risk of errors. A quieter environment promotes better communication and focus.

Smartphones Reduce Paging Noise

A study on replacing overhead paging with smartphones reported that overhead pages were eliminated after implementation. Transitory noises decreased by two-thirds (P < 0.001). The findings point to smartphone-based communication as a way to reduce these sources of hospital noise.

Limits of Noise-Reduction Interventions

In a cesarean-delivery study, a visual alarm program reduced noise by 0.7 dBA, but the reduction did not reach a discernible 3-dB change or reduce startle events. The overhead-paging study at the University of Maryland Medical Center collected sound data only during day shifts, leaving its effect at night unknown; measurements from empty patient rooms also excluded noise from in-room care. These findings show that intervention results may be modest and that measurement conditions can leave important gaps.

Sound Levels Across Delivery Settings

One study measured an average sound level of 58.03 ± 7.66 dB in the delivery room during the first hour of a newborn’s life, with readings ranging from 40.30 to 78.0 dB. A separate clinical study reported average labor-ward noise reaching 87 dB(A) and maximum levels reaching 122 dB(A). A third source cites a hospital in India where the highest nighttime level in the obstetrics and gynaecology ward was 71.9 dB LAeq, with slightly lower levels in the labour ward. These measurements come from different studies and settings, so they should not be treated as directly comparable readings.

Given these findings, it's clear that noise reduction strategies are essential. Simple changes in behavior and room setup can create a more peaceful and supportive atmosphere for newborns, mothers, and healthcare teams.

Creating a Quieter Future

Reducing noise levels in delivery rooms requires a conscious effort from everyone involved. By implementing simple strategies and fostering a culture of quiet, we can create a more supportive and healing environment for newborns, mothers, and the dedicated healthcare professionals who care for them. Prioritizing noise reduction is an investment in better health outcomes and a more positive birthing experience.

Noise and Team Communication

A 2023 study set out to comprehensively analyze noise during cesarean deliveries, using sound-level meters to establish baseline levels and describe acute noises that could trigger a human startle response. It also evaluated whether a visual alarm system could mitigate excessive noise. Its report says cesarean delivery-room noise is excessive and may contribute to impaired communication among the operating team. The supplied summaries describe the study’s aims and concern, but do not establish that the visual alarm system was effective.

Birth Centers Beyond the Traditional Model

A January 30, 2026 article describes family birth centers as evolving beyond the traditional labor-and-delivery model. It links this change to a new generation of mothers reshaping expectations around childbirth and postpartum care. The source does not specify particular noise-reduction technologies or design features.

Room Design and the Labor Environment

A systematic review of birthing-room design identified labor-room noise as an unpleasant factor and, citing Pirdel and Pirdel (2009), a major predictor of pain for multiparas. A related source says that birthing women need high-quality care alongside a familiar, calm, safe, and secure environment, and that the physical healthcare environment affects health and well-being. Together, these sources place noise within the broader challenge of creating supportive birth environments.

Acoustic Comfort in Maternity Care

A 2022 case study examined noise disturbance in a maternity ward, noting that hospitals contain spaces with different sensitivity to noise as well as activities and equipment that can contribute to high levels. Its analysis included sound-insulation measurements between bedrooms. Wavecare describes its sensory delivery room as designed to enhance the experience for both the woman or couple and staff, using light, sound, and natural scenery to support a homely atmosphere. The supplied material describes the design’s purpose but does not provide measured outcomes.
