Medical Research: What is the background for this study?
Dr. Wenqi Gan: In epidemiologic studies on health effects of noise exposure, community noise is typically assessed using noise prediction models, occupational noise is assessed using self-reports or historical records. These methods are able to estimate community noise exposure in residential areas and occupational noise exposure in the workplace; however, these methods are not able to accurately reflect actual personal noise exposure in the home and workplace. The lack of personal noise exposure information is a major limitation of previous studies, which could cause underestimations of the true health effects of noise exposure. Bilateral high-frequency hearing loss, an objective indicator for long-term exposure to loud noise, may be used to investigate health effects of noise exposure.
Medical Research: What are the main findings?
Dr. Wenqi Gan: This study includes 5223 people aged 20-69 years who participated in the US National Health and Nutrition Examination Survey 1999-2004. Compared with people with normal high-frequency hearing, people with bilateral high-frequency hearing loss were approximately two times more likely to have coronary heart disease. This association was particularly striking for people who were chronically exposed to loud noise in the workplace or leisure time. For example, for currently employed workers with occupational noise exposure history, the possibility of having coronary heart disease increased more than four times. This study confirms that chronic exposure to loud noise is associated with increased risk of coronary heart disease.

MedicalResearch: What is the background for this study? What are the main findings?Dr. Mosnier: Association between hearing impairment and cognitive decline has been established; however, the impact on cognition through cochlear implantation in profoundly deaf elderly patients is not known. The focus was to determine the impact of hearing rehabilitation including cochlear implant on cognitive functions, in addition to the influence of cognitive factors on cochlear implant outcomes over time.

MedicalResearch.com Interview with: Dr. Peter Torre III PhDAssociate Professor, AudiologyDirector, Recreational Noise Exposure and Hearing Lab
San Diego State University
Medical Research: What is the background for this study? What are the main findings?
Dr. Torre: The primary purpose of our study was to evaluate hearing sensitivity in HIV+ and HIV- adults. And subsequently, in HIV+ adults only, to examine whether HIV disease variables or treatment was associated with hearing sensitivity.
The main findings were that HIV+ adult had poorer hearing for both the lower and higher frequencies compared with HIV- adults, although we did not find any significant associations between HIV variables and treatment variables with hearing loss.
