This study presents normative brain-stem auditory evoked response (BAER) values for school-aged children (4-14 years). Findings reveal significant age and sex influences on specific BAER components, informing normative data development.

Area of Science:

  • Neuroscience
  • Audiology
  • Developmental Psychology

Background:

  • Brain-stem auditory evoked response (BAER) is a key electrophysiological measure for assessing auditory pathway function.
  • Establishing normative data is crucial for interpreting BAER results in pediatric populations.
  • Previous studies have indicated potential age and sex differences in BAER, but comprehensive normative data across a wide age range is needed.

Purpose of the Study:

  • To establish normative values for brain-stem auditory evoked response (BAER) in a large sample of typically developing school-aged children.
  • To investigate the influence of age and sex on various BAER components within this age group.
  • To develop age- and sex-adjusted normative data for improved diagnostic accuracy.

Main Methods:

Related Experiment Videos

  • A large cohort of 174 normal school-aged children (4-14 years) underwent BAER testing.
  • Data analysis focused on identifying significant effects of age and sex on specific BAER waveform components.
  • Normative values were computed, accounting for identified age and sex influences.

    • Main Results:

    • Significant influences of sex were observed on certain BAER components.
    • Significant influences of age were identified on other BAER components.
    • Normative values were calculated and adjusted based on these age and sex effects.

    Conclusions:

    • Age and sex are significant factors influencing brain-stem auditory evoked response (BAER) measures in school-aged children.
    • The derived normative values, adjusted for age and sex, provide a more accurate reference for clinical audiological assessment.
    • These findings contribute to a better understanding of auditory development and maturation during childhood.
