Study of Noise Loudness and Sharpness Effects on Cognitive Performance on Male Students of Tehran University of Medical Sciences

بهداشت و ایمنی کار, 2022
Introduction: The noise could affect some aspects of human health, including the cognitive performance. In addition to sound pressure level and exposure time, the psychoacoustic features of noise may cause destructive effects on humans.

Evaluation of Software‐Optimized Protocols for Acoustic Noise Reduction During Brain MRI at 7 Tesla

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background MR‐generated acoustic noise may be particularly concerning at 7‐Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized.

Impact of pre‐examination video education in Gd‐EOB‐DTPA‐enhanced liver MRI: A comparative study

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 34-41, March 2025.
This study evaluates the effects of pre‐examination video education on patient anxiety, satisfaction and image quality in Gd‐EOB‐DTPA‐enhanced liver MRI. We found that video education significantly reduced anxiety, increased patient satisfaction and improved image quality compared to standard pre‐MRI guidance, highlighting the potential of video ...

Non-uniform temporal weighting of intensity in audition and vision: The signature of an evidence integration process?

Acta Acustica
Non-uniform temporal weights (TWs) are often reported regarding the perceptual evaluation of dynamic auditory and visual information, such as perceptual judgments of the overall intensity of time-varying stimuli.

Acting authentically: Using play to cultivate authentic interrelating in role performance

Journal of Organizational Behavior, EarlyView.
Summary Research is increasingly demonstrating that authenticity and human connection are fundamental and interrelated human needs. However, organizational roles often constrain authenticity and connection in workplace interactions, especially roles that are highly scripted.

Developing methodologies to study perceived sound qualities of violins*

Acta Acustica
Violin makers and acousticians have long sought correlations between sound qualities, construction parameters and vibroacoustic measurements. This is challenging for three main reasons: it is difficult to build violins reliably enough to ensure that the ...
