Sound levels for neonates in transit

J P Shenai

    The Journal of Pediatrics
    |May 1, 1977
    PubMed
    Summary

    Neonatal intensive care unit (NICU) infants face hazardous noise levels during transport, especially in helicopters. Sound attenuation measures are crucial for infant stabilization during transit.

    Area of Science:

    • Neonatal intensive care
    • Environmental health
    • Transport medicine

    Background:

    • Neonatal intensive care units (NICUs) provide critical care for vulnerable infants.
    • Infant transport involves exposure to various environmental stressors.
    • Noise pollution is a recognized stressor with potential health implications.

    Purpose of the Study:

    • To quantify sound levels experienced by neonates in a NICU and during different modes of transport.
    • To assess the potential risks associated with noise exposure during infant transport.
    • To advocate for noise reduction strategies during neonatal transport.

    Main Methods:

    • Sound level measurements were conducted in a NICU setting.
    • Acoustic monitoring was performed during ambulance, rotary-wing aircraft, and fixed-wing aircraft transport.
    • Decibel (dB) levels were recorded under typical conditions.

    Main Results:

    • NICU sound levels ranged from 58 to 70 dB.
    • Transport sound levels were consistently higher than NICU levels.
    • Rotary-wing aircraft transport exhibited the highest sound levels, exceeding 90 dB.

    Conclusions:

    • Neonates undergoing transport are exposed to potentially harmful noise levels.
    • Noise exposure during transport may pose a significant risk to infant well-being.
    • Implementing sound attenuation methods is essential for stabilizing infants during transport.
