The document sets out to provide information and guidelines for testing babies in the first few months of life by AABR using primarily air conduction click stimuli for the purposes of screening for hearing loss. Clicks are widely employed for neonatal screening and the majority of reported studies have employed the click stimulus. However in the future it is possible that other electrophysiological methods, such as the tone pip ABR, might become an alternative technique.
Equipment that carries out AABR testing is available from some manufacturers. The test protocols for this type of equipment are usually fixed and are specific to different manufacturers. Data collection parameters, implementation of the test, and scoring algorithms will be discussed. General aspects of ABR methodology have been reported previously and will not be included in detail in this document.
