Effects Of Primary And Secondary Cigarette Smoke On Auditory Function: A Systematic Review, Hilary Mcmanus

Dissertations, Theses, and Capstone Projects

Objective: The goal of this paper was to systematically review literature in order to investigate the effects of active and passive cigarette smoke on auditory function when assessing outcome measures including pure tone audiometry, otoacoustic emissions, high-frequency audiometry, and auditory evoked potentials.

Methods: A comprehensive search using the Medline Complete database was conducted to identify relevant studies published after 2005. Inclusion criteria included the use of pure tone audiometry, high-frequency audiometry, otoacoustic emissions, and/or auditory evoked potentials to examine the effect of primary or secondary cigarette smoke. Studies involving noise exposure or other confounding factors were excluded.

Results: A total …

Screening For Hearing Loss: Physician Attitudes And Practice, Theresa N. Vitale

Dissertations, Theses, and Capstone Projects

Age related hearing loss (ARHL) is considered a public health hazard in large part due to the negative health outcomes with which it is associated, such as, cognitive decline, increased risk of falling, social isolation and depression. Despite the health-related costs of ARHL, physician’s rarely screen older adults for ARHL. Some of the reasons previously cited include a lack of time and resources in medical offices, a lack of reimbursement for such measures, or lack of knowledge of risk factors associated with hearing loss. The latter is problematic as improved communication among physicians and their patients is an important correlate …

Hearing Studies In Old Mice: The Effect Of Pre-Pulse Inhibition On The Acoustic Startle Response, Ashley B. Hillyard, Nicolette S. Chuss

Senior Honors Projects, 2010-2019

The purpose of this study pertains to hearing in the species Peromyscus maniculatus (deer mice) — specifically their responses to a startling sound. Approximately seven mice were tested between four and five years of age, approaching the lifespan of this species. By means of an accelerometer, which measures a reflexive, motor response, the mice were presented with an acoustic startle-eliciting stimulus (SES) — that is a loud, startling, unexpected sound. During the study, the mice were also presented with a softer, less-intense stimulus — known as a pre-pulse — slightly before the more intense sound. This pre-pulse stimulus was in …
