A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein
Dissertations, Theses, and Capstone Projects
The prevalence of noise induced hearing loss (NIHL) is a public health concern with government regulations (i.e. OHSA, NIOSH) in place to protect employees in occupational settings. Sound pressure levels (SPL) of various industries have been measured and exposure dosages monitored as per the national regulations. Previous research has demonstrated that occupational exposure to loud noise has led to audiometric evidence of NIHL. Thus, it raises the question about the impact of occupational exposure to music on hearing. For the purposes of this capstone, literature pertaining to occupational music exposure levels, and the effects on both hearing threshold levels and …

Microbeam radiation therapy (MRT) is an experimental radiosurgical technique under investigation as a treatment for presently incurable brain lesions such as gliomas. The treatment involves the irradiation of a macroscopic target volume by delivering a very high dose to many microscopic wide sub-volumes. A very high dose rate and very low beam divergence are prerequisites for MRT, which at present necessitates the use of synchrotron radiation. The complex structure of the radiation field combined with the very high dose rate pose a challenge for conventional dosimetry. To address the dosimetric inadequacies, a complete and standalone dosimetry system was developed for …

The treatment of mucosal Head and Neck (H+N) cancers with radiotherapy has seen considerable technological development over recent years; from large non-conformal fields, to three- Dimensional Conformal Radiation Therapy (3-D CRT) and subsequently the introduction of Intensity Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT) and other radiation therapy delivery techniques, such as proton therapy. When compared to older "conventional" techniques, the IMRT planning process results in improved dose to tumour volumes, whilst simultaneously reducing Organ at Risk (OAR) dose; i.e. an improvement of the therapeutic index. This dosimetric improvement translates into clinical benefits; especially in terms of reduced …
