Acoustic Rhinometry (AR) evaluates the geometry of the nasal cavity by
means of acoustic reflections. Since it is a recently developed testi
ng procedure, little is known about the various environmental factors
that may affect measurements made with this technique. The acoustic si
gnal generated from the source and received by the microphone(s) withi
n the system are audible tones. The system is currently operated in or
dinary office settings. Therefore, other noise present in the testing
environment may interfere with test measurements. This study evaluates
the effects of different sources of environmental noise on Acoustic R
hinometry measurements.
