AUDIOLOGY RESEARCH 2004
A collection of photographs from research labs |
Legend: A. Masters student Sarah Parker from Perth averages electrical signals from her head in a laboratory class in our unit Evoked Responses in Clinical Diagnosis; B. Masters student Fred Bienvenu from Victoria is wired for sound (Auditory Middle Latency Response testing); C. Masters student Brenden Van Fleet concentrates hard on minimizing muscle activity while recording minute signals from his auditory brainstem; D. Masters students Philippa Hatch and Sarah Parker take a break while collecting cortical evoked potentials from the somatosensory cortex (note electrical stimulator on Sarah's wrist); E. PhD student Norman Zakaria from Malaysia studies directional hearing ability in children with Central Auditory Processing Disorder (CAPD). His setup tests hearing in 3D. Norman's ground-breaking work has shown that most children with CAPD are unable to tell left from right with only timing cues; F. Perth PhD student Daniel Brown prepares to measure microvolt signals from his ear drum in a test called Tympanic Electrocochleography. Daniel's work follows from his previous work in guinea pigs where he studied the generation of the electrical signals from the inner ear. His work has been published internationally, and should form the basis of non-invasive testing for various forms of tinnitus and auditory tumours. G. In developing his diagnotic testing, Daniel has worked with Dr. Robert Patuzzi (course co-ordinator in audiology) in developing cost-effective and electrically quiet amplifiers to magnify the minute signals from the inner ear and auditory brainstem. The prototype circuits rarely look impressive! H. Daniel Brown's work requires the development of sophisticated computer software to record and analyze the electrical signals evoked by sound. Daniel's present system is up to 20 times faster than the systems used by many audiologists in collecting similar data. I. Typical recordings of minute signals from the ear drum of nerve responses from within the inner ear. These recordings can be used to investigate the origin of tinnitus in individuals, and understand the mechanisms of hearing loss in various pathologies. The work will soon be extended in various Masters research projects to diagnose deafness in newly born babies. Other research projects have included a Chinese speech test via Microsoft Powerpoint, acoustic analysis of classrooms, the post-auricular muscle response for objective audiometry and screening, the history of audiology in WA and Australia, issues in central auditory processing disorders (CAPD) in children, various tests of client satisfaction in hearing aid rehabilitation, high-frequency audiometry, evoked responses and auditory tumours, issues in paediatric and geriatric audiology, and many more. Present research projects include issues in tinnitus, CAPD, neonatal teting, play audiometry, and more. |  |
