The purpose of this paper is to provide an instructional format in the presentation of the clinical application of electroacoustic impedance measurements. Journal articles and impedance procedural booklets were used as a source of data for the information contained in the learning packet. Fundamentals of acoustic theory were treated to show the conceptual relationship of acoustic impedance and acoustic admittance. The terminology, normative data, and clinical interpretation of static acoustic impedance measures were examined. Diagnostically significant variables of the tympanogram were related to the audiometric-medical status of the patient. Clinical application of the acoustic reflex was investigated through descriptions of various pathologies and the particular indications expected in acoustic reflex testing for those pathologies . The learning packet is divided into four sections: impedance versus admittance, static acoustic impedance measurements, tympanometry, and acoustic reflex.
