The motion of the face carries great importance in research about speech production and perception. The suitability of a novel UVbased video recording system to track small facial motions during speech is examined. Tests are performed to determine the calibration and system errors, as well as the spatial and temporal resolutions of the setup. Results of the tests are further evaluated through k...

The purpose of this study was to assess the relationship between the directivity of a directional microphone hearing aid and listener performance. Hearing aids were fit bilaterally to 19 subjects with sensorineural hearing loss, and five microphone conditions were assessed: omnidirectional, cardioid, hypercardioid, supercardioid, and "monofit," wherein the left hearing aid was set to omnidirect...

This study examined differential performance of normally hearing subjects using a tactile device on the dominant versus non-dominant hand. The study evaluated whether tactual sensitivity for non-speech stimuli was greater for the dominant hand as compared with the non-dominant hand, and secondly, whether there was an advantage for speech presented tactually to the dominant hand, resulting from ...

INTRODUCTION  Cochlear implants may guarantee sound perception and the ability to detect speech at a close-to-normal hearing intensity; however, differences have been observed among implantees in terms of performance on discrimination tests and speech recognition. OBJECTIVE  To identify whether patients with post-meningitis deafness perform similarly to patients with hearing loss due to other...
