| dc.description.abstract | Tourette syndrome is an inherited neurophysiologic disorder with onset in childhood, characterized by multiple physical (motor) tics and at least one vocal (phonic) tic. Between 0.4% and 3.8% of children ages 5 to 18 may have Tourette′s; the prevalence of other tic disorders in school-age children is higher, with the more common tics of eye blinking, coughing, throat clearing, sniffing, and facial movements. Coprolalia (the spontaneous utterance of socially objectionable or taboo words or phrases) is the most publicized symptom of Tourette′s, but only 19.3% of male and 14.6% of female Tourette′s patients exhibit it. People with Tourette Syndrome often feel immense anxiety about expressing their tics, particularly when they have vocal tics or coprolalia. This anxiety may make symptoms worse for some people, and frequently leads to social isolation.
If we can design a mask to reduce the intensity of vocal tic or coprolalia, the patients with Tourette syndrome will have a better life quality. The main emphasis in this study are three elements of sound-absorbing principle, the resonance structure, vibrator plate , sound-absorbing cotton. Through analysis, using different permutations and combinations, in order to seeking the efficiency of sound suppression by using design masks. Otherwise, a new novel multilayer vibrating plate design was successfully 3D printed in conjunction with the 3D scanned data for the customized face features. The field test results revealed an effective sound suppression can be fulfilled in the range of 60%~90% for the frequency range 100-2500Hz. Therefore, the second year project goal aims to continuously design and develop an alternative low-cost, vacuum structure for the patients of Tourette syndrome. | en_US |
