Abstract: |
This study is a collaboration between the Polytechnic of Turin and the Acoustic Group of South Bank University of London. Voice use play a significant role in the causation of many common voice disorders caused by chronic and recurrent conditions, which result from an incorrect use of the voice or from poor acoustic conditions in the environments where the voice is used. Scientific data in literature show that the singers of classical lyric orchestras are exposed to high risk of damage to the vocal apparatus due to the intense effort they have to face during the artistic performances. New protectionist laws impose to evaluate all different risk factors in the workplaces. All categories of workers are included and, among them, workers employed in recreational activities and shows should be considered. The object of this dissertation is an investigation in singers’ vocal parameters in order to understand how they change under different acoustical conditions. At the beginning the acoustics of 5 different spaces was analyzed: the Sir Jack Lyons Theatre and a rehearsal room, both located at the Royal Academy of Music in London, and the anechoic, semi-reverberant and reverberation chamber located at the LSBU. After the room’s acoustics study, four singers volunteer (3 females and 1 male) were monitored in those different spaces and they were asked to execute some vocal exercises such as scales or arpeggios for 3 minutes. To take this measurements two battery powered devices were used and during the test an accelerometer was attached on their throat using a medical secure silicone adhesive wich was removed at the end of each test by a specific Uni-Solve adhesive remover wipe. During the test in the anechoic chamber they were asked to sing an opera aria too in order to record their voice to make auralizations with the software CATT. The auralization is typically the final stage in a predictive assessment and its aim is to demonstrate of a space’s prospective performance to both experts and non experts in acoustics. At the end of each test they were asked to fill a short questionnaire about their personal perception singing in those different venues.
