Mannell R.H., (2013) Oral-Nasal Airflow Workshop, Macquarie University
Workshop aims
To measure the rate of airflow through the mouth and nose during the utterance of various passages and nonsense sentences.
To measure the sound pressure level of that part of the vocal output which is emitted through the nose and the sound pressure level of that part which is emitted through the mouth.
The measurements of airflow will be compared with the oral/nasal sound pressure measurements.
Pervasive, vowel intrinsic, and contextual "nasality" will be examined.
Workshop video
Equipment setup and experimental procedure is covered in the oral-nasal airflow workshop video. Various versions of this video can be found on the movies index page.
You should also have a look at a number of short video clips that examine velum opening from above using a nasoendoscope. Also, patterns of velum opening from the side can be seen in a a series of xray movies on this site.
Review of nasality
View a brief overview of the functional physiology of velum opening and of oral-nasal airflow.
Methodology

Results
