This practical book contains the fundamentals, methods, and guidelines for the most important testing procedures in objective audiometry. It can be directly applied to daily work and quickly answers the questions: "How do I apply the methods?" and "How can I correctly evaluate and interpret the results?" Objective hearing testing methods are essential for the detection and management of congenital and acquired hearing disorders in children, and particularly for monitoring those who did not pass the newborn hearing screening. The book provides an overview of the significantly expanded inventory of methods in impedance audiometry, otoacoustic emissions, and the diverse spectrum of auditory evoked potentials, from electrocochleography to late and event-related potentials, while considering current recommendations and guidelines on audiometry.
