Insights
Newborn infants demonstrate active listening skills, responding to and preferring specific sounds like speech and music. Excessive environmental noise can disrupt their sleep and attention, impacting development.
Area of Science:
- Neonatal Auditory Perception
- Developmental Psychology
Background:
- Understanding newborn hearing is crucial for clinical practice.
- Previous research highlights varying assumptions influencing auditory studies.
Purpose of the Study:
- To summarize research on newborn hearing and behavioral responses to sound.
- To inform clinicians about auditory development and environmental impacts.
Main Methods:
- Review of existing research literature on neonatal auditory responses.
- Analysis of studies examining responses to speech, music, and other sounds.
Main Results:
- Newborns are active listeners with preferences for certain sounds.
- Auditory system immaturity does not preclude discrimination of speech sounds.
- Environmental noise can negatively affect newborn sleep and attention.
Conclusions:
- Newborns exhibit sophisticated auditory discrimination abilities.
- Clinicians should be aware of noise pollution in nurseries.
- Further research can refine understanding of auditory development.
Abstract:
This article, addressed to clinicians caring for and interacting with newborns, summarizes information from the research literature about newborn infants' hearing and behavioral responses to sound. While the emphasis is on current knowledge, older studies show how the investigators' assumptions have influenced the questions they have asked. Although these studies do not make up a neat package of information for clinicians, they do reveal broad outlines of newborn hearing abilities and the affects of sound on sleeping, quieting from crying, habituating, and paying attention. The newborn's responses to and preferences for particular sounds such as speech, music, and heartbeats are reviewed. These studies present the term newborn as an active listener and learner who, despite a somewhat immature auditory system and a limited repertoire of behavioral responses, is highly discriminating regarding the sounds of speech and whose efforts at sleeping, quieting, and paying attention may be hindered by noise such as that commonly found in hospital nurseries.
