Improving the reproducibility of acoustic rhinometry: a customized stand giving control of height and angle

  • Edward W. Fisher (a1) and Adrian B. Boreham (a2)

Abstract

Control and recording of the position of the acoustic rhinometer in relation to the nostrils is important for serial measurements. Several technical factors must be controlled, including the angle of the incident acoustic wave. We describe a simple, newly-designed, rhinometer stand which allows control of height and angle, and hence improves the reliability of serial measurements in clinical and physiological work.
