Wideband tympanometry (sometimes referred to as Wideband Acoustic Immitance) is a approach to performing middle ear assessment with the aim of providing the clinician with more diagnostic information without any additional effort. Measuring tympanograms for all frequencies in a single pressure sweep provide the traditional 226 Hz tympanogram as well as new information such as the absorbance graph, resonance frequency tympanogram and wideband averaged tympanogram. By performing multiple tympanograms clinicians are able to gain a greater understanding of the status of the middle ear and be able to make a more accurate or definitive diagnosis.
