Acoustic Rhinometers allow a very rapid non invasive examination of the nasal cavity using a sound pulse technique. Reflections of the sound pulse, produced by changes in the. cross sectional area within the nose, are processed by a PC to provide a plot of the area as a function of distance into the nose. Numerical information such as the area at certain distances and volumes between certain points in the nose can also be presented.
