Phone: Infant ABR: Click vs CE-Chirp
Course: #27898 1 Hour
Historically, ABRs have been evoked using click stimulus. Recently, the CE-Chirp stimulus was developed to maximize the temporal synchronization of the responses from the underlying neural components. Few researchers, however, have investigated the utilization of chirp stimulus with newborns. In this course, findings will be presented from a large study with newborns examining ABRs to air and bone conducted CE-Chirp versus click stimuli. A multitude of stimulus manipulations was investigated. Clinical application will be discussed.
