Evaluation Of Swallowing Related Measures In Different Head And Neck Postures In Healthy Young And Older Adults, Mabell Vargas

FIU Electronic Theses and Dissertations

This study evaluated swallowing related measures (oral transit time and number of swallows, tongue force and lip force) and different head and neck postures in a group of healthy young adults and older adults. Participants consisted of 19 healthy young and 17 healthy old. They were asked to ingest 2 different liquid consistency to measure the time they take to swallow and the number of swallows. The maximum tongue and lip force was measured with the IOPI device for 3 seconds and repeated 3 times.

The results of the study showed that the number of swallows is not significant regardless …

Kemar Hats Head Orientation Directivity, Samuel D. Bellows, Timothy W. Leishman

Directivity

This directivity data set for a KEMAR head head-and-torso simulator (HATS) includes head orientations in 14 directions in 5° steps starting from 0° to 40° and then in 10° steps from 40° to 90°. The full spherical measurements followed at an a = 0.97 m radius with the mouth aperture at the spherical center. The sampling density and distribution followed the AES 5° dual-equiangular sampling standard, omitting the south pole (θ = 180°). Thus, each spherical directivity assessment included 36 polar-angle θ samples and 72 azimuthal-angle ϕ samples. The presented data include 22 1/3-octave bands, ranging from 80 Hz …
