Auditory Brainstem Response (ABR) threshold measurements

A student in biomedical engineering at the RUG has been working on a project at PENTO testing two types of stimuli for Auditory Brainstem Response (ABR) threshold measurements; the main question was whether one or the other was more suitable for measurements in neonates (those who get referred to us for failing an automated screening measures in the first week after birth). The main conclusion is that the ABR signal of peak V is significantly larger in Chirp-evoked ABR-responses than in conventional click-evoked ABR-responses. The figure shows the amplitude for many different levels for the two stimuli.
