A FULL ASSESMENT OF MIDDLE EAR REFLECTANCE AND CONDUCTANCE CAN BE MADE EASIER WITHOUT WIDEBAND REFLECTANCE DEVICES Technology Leader in Otoacoustic Emissions The most common probe tone frequency used in tympanometry is 226 Hz. Using 226 Hz, well known and categorized tympanogram shapes can be obtained. When testing infants younger than four months, a probe tone frequency at 1000 Hz is recommended. For many pathologies, the optimal probe tone frequency is not a well established value. Multifrequency tympanometry can improve on middle ear diagnostics, but can be time consuming with analysis sometimes...
