. This study aimed to assess noise levels in various units in hospitals and explore the correlation between healthcare employees' daily noise exposure level () and their stress and symptoms. . A healthcare facility was selected to study noise pollution. Personal noise dosimeters were used during 8-h working shifts. Data were collected from 126 employees using the 36-item 'A stress scale' and a socio-demographic information form. . The results of noise measurements exceeded World Health Organization and US Environmental Protection Agency recommended limits at all sites. The lowest (52 dB) was detected in the endocrinology clinic, while the highest (91 dB) was recorded in the podology unit. According to the stress scale scores, the lowest mean psychological symptom score (PsSS), physiological symptom score (PhSS) and total scale score (TSS) were observed in diagnostic units with 35 ± 14, 41 ± 14 and 76 ± 27, respectively, while the highest mean PsSS, PhSS and TSS were observed in the polyclinics with 44 ± 6, 64 ± 10 and 107 ± 10, respectively. The PsSS of employees exposed to noise () above 75 dB was found to be higher than for other employees. . above 75 dB can increase psychological symptoms in healthcare employees.

Background: Exposures to hazardous noise causes irreversible injury to the structures of the inner ear, leading to changes in hearing and balance function with strong links to age-related cognitive impairment. While the role of noise-induced hearing loss in long-term health consequences, such as progression or development of Alzheimer's Disease (AD) has been suggested, the underlying mechanisms and behavioral and cognitive outcomes or therapeutic solutions to mitigate these changes remain understudied. This study aimed to characterize the association between blast exposure, hearing loss, and the progression of AD pathology, and determine the underlying mechanisms.

Objective: To examine the association between individual, cumulative leisure noise exposure (CLNE), acceptable yearly exposure (AYE) and tinnitus among a nationally representative sample of Canadians.
Design: In-person household questionnaires were used to evaluate leisure noise exposure across age, sex, household income and tinnitus: ever experienced, previous year, frequent, bothersome. High (≥85 dBA, LEX), low (<85 dBA, LEX) CLNE and AYEs were defined according to occupational limits.

Background: Photon-counting detector (PCD) technology has the potential to reduce noise in computed tomography (CT). This study aimed to carry out a voxelwise noise characterization for a clinical PCD-CT scanner with a model-based iterative reconstruction algorithm (QIR).
Methods: Forty repeated axial acquisitions (tube voltage 120 kV, tube load 200 mAs, slice thickness 0.
Hazardous exposures and engineering controls in the landscaping services industry.

Landscapers are exposed to noise, carbon monoxide (CO), respirable dust, and respirable crystalline silica (RCS) generated from the tools they use. Although engineering controls are available to reduce these exposures, no previous study has evaluated chronic exposures to landscapers in different work settings and compared exposures from landscaping tools with and without engineering controls. This field study of workers in the landscaping services industry documented the occupational exposures of 80 participants at 11 varied worksites to noise, CO, respirable dust, and RCS using personal breathing zone sampling.

Purpose: This study investigated the impact of the field of view (FOV), voxel size, and exposure parameters on the contrast-to-noise ratio (CNR) in cone-beam computed tomography (CBCT).
Materials And Methods: A SedentexCT phantom was scanned using 3D Accuitomo 170 across 3 FOVs (40×40 mm, 60×60 mm, 80×80 mm). Each FOV had 4 settings for kVp and 3 for mA.
