Background and Objectives: The methods for testing Eustachian tube function include conventional, radiological, and physiological tests. Sonotubometry is one of the physiological test methods. Sonotubometry checks the openness of the ear canal by transmitting 7 kHz narrow-band noise through the nasal cavity and measuring sound energy in the external canal using a microphone. To confirm the clinical significance, the Williams test (Y-226 Hz) was performed and compared to sonotubometry by analyzing their results. Materials and Methods: We recruited a total of 40 participants (80 ears), consisting of 20 men and 20 women between the ages of 20 and 40, who did not have any rhinological or otological issues. The subjects were selected based on pure tone audiometry, categorized using the Williams test (Y- 226 Hz), and their sonotubometry results were compared. Results: The sonotubometry results for the normal group indicated longer duration, greater elevation, and a wider dimension compared to the Eustachian Tube Dysfunction (ETD) group. Furthermore, a correlation was observed between each variable. Conclusion: The Williams test (Y-226 Hz) confirmed tube status as either open or closed based on changes in impedance with tube opening. However, Sonotubometry had the advantage of quantitatively confirming not only whether the Eustachian tube was open but also the duration of tube opening and the amount of ventilation during that time.
