Acoustic rhinometry is a diagnostic measurement of cross sectional area and length of the nose and the nasal cavity through acoustic reflections.[1] It can be used to measure nasal anatomical landmarks, and nasal airway changes in response to allergen provocation tests. The size and the pattern of the reflected sound waves provide information on the structure and dimensions of the nasal cavity, with the time delay of reflections correlating with the distance from the nostril.
