Neuro-Audio Study: New Pediatric ABR Normative Data Published in Brazil

Researchers from the Federal University of São Paulo (UNIFESP/EPM), Brazil, have published the results of a study addressing one of the key challenges in pediatric audiology — establishing normative Auditory Brainstem Response (ABR) values for children up to 3 years of age using the Neuro-Audio system by Neurosoft.

Because recorded ABR parameters may vary depending on the diagnostic system used, equipment-specific normative reference data are essential for accurate interpretation of test results and early identification of hearing disorders. Until now, independent reference values for the Neuro-Audio system had only been available for adults, limiting the interpretation of pediatric ABR recordings.

The study included more than 200 children with confirmed normal hearing, ranging in age from two weeks to three years. Based on the collected data, the researchers established age-specific normative values for ABR wave latencies and interpeak intervals and evaluated the influence of age, sex, and test ear on the recorded responses.

The implementation of these normative data into clinical practice will help audiologists, hearing care professionals, and neurologists assess auditory brainstem maturation more accurately and improve the early detection of both peripheral and central hearing disorders during the first years of life.

We are pleased to see Neurosoft technologies continuing to support international scientific research and contribute to the advancement of objective hearing assessment in children.
