This study establishes normal values for Distortion Product Otoacoustic Emissions (DPOAE) in newborns. DPOAE testing in 185 infants found results comparable to other equipment, aiding hearing assessments.

Area of Science:

  • Audiology
  • Neonatal Hearing Screening

Background:

  • Distortion Product Otoacoustic Emissions (DPOAE) offer an alternative to Transient Evoked Otoacoustic Emissions (TEOAE).
  • Establishing normative data is crucial for accurate interpretation of DPOAE in neonatal hearing assessments.

Purpose of the Study:

  • To determine reference values for DPOAE in a cohort of healthy newborns.
  • To compare DPOAE measurements obtained with the Madsen Celesta 503 to existing literature.

Main Methods:

  • DPOAE were measured in 185 healthy newborns at 4 days postpartum.
  • Measurements were taken at 0.5, 1, 2, 4, and 8 kHz using specific unequal stimulus levels (L1=65 dB SPL, L2=50 dB SPL).
  • Statistical analysis included calculating 5% quantiles and medians for DPOAE amplitudes, examining sex and side effects.

Main Results:

  • DPOAE were present in 92.4% of the tested ears.
  • Reference limits (5% quantile and median) were established for each frequency and ear.
  • A significant sex effect was observed at 4 kHz (higher in females), and a sex-by-side interaction at 2 kHz.

Conclusions:

  • The study provides normative DPOAE data for healthy newborns, useful for clinical audiology.
  • The findings support the use of DPOAE as a reliable method for neonatal hearing screening.
  • The established reference values facilitate comparison with data from different equipment.
