Objective:

To identify, describe, and categorize noise sources in the NICU and examine their potential impact on preterm infants, emphasizing the significance of these impacts.

Approach:

Key Findings:

• Most studies reported sound levels substantially above recommended limits, indicating a critical need for intervention.
• Major noise contributors included alarms, staff conversations, and incubator-associated equipment, which could be targeted for reduction.
• Respiratory support devices produced the highest internal noise levels, raising concerns about their use in sensitive environments.
• Interventions yielded short-term improvements but rarely sustained reductions, highlighting the need for more effective strategies.

Interpretation:

NICU noise is a modifiable risk factor with significant developmental implications, necessitating further research on long-term effects.

Limitations:

• Current evidence on long-term neurodevelopmental implications of early noise exposure remains heterogeneous and largely observational.
• Incubators provide partial attenuation of environmental noise but do not fully protect infants, and excessive shielding may reduce meaningful auditory input.

Conclusion:

Future strategies should integrate environmental design, technological innovation, and infant-focused interventions to create safer acoustic conditions, emphasizing the importance of addressing noise pollution for developmental outcomes.
