The effect of moderate broadband noise on cognitive performance: a systematic review
Abstract Individuals in occupational settings are often exposed to moderate levels (e.g., < 85 dBA) of background noise (i.e., broadband noise) while performing cognitive-based tasks. Exposure to such noise may affect individuals’ cognitive performance and thus affect desired performance level (e.g., safety performance). The present review outlines the effect of moderate broadband noise on indices of cognition such as reaction time, attention, short-term and long-term memory, and high(er)-order cognitive tasks such as decision-making, mental arithmetic, grammatic reasoning, or reading comprehension. The present review highlights limitations associated with moderators, and their effect on broadband noise. 43 studies ranging from 1980 to February 2023 were selected and analysed to investigate this issue. Reviewed results offered minimal evidence for a negative effect of moderate broadband noise on cognitive performance. Negative effects that were found, were often evident only under specific circumstances. The roles of cognitive load, repeated session, and individual differences (e.g., sex) were found to differ from theoretical predictions based on evidence from broader noise(s), which highlights the distinctive characteristics of the mild stressor; hence an area for future research.
期刊介绍:
Cognition, Technology & Work focuses on the practical issues of human interaction with technology within the context of work and, in particular, how human cognition affects, and is affected by, work and working conditions.
The aim is to publish research that normally resides on the borderline between people, technology, and organisations. Including how people use information technology, how experience and expertise develop through work, and how incidents and accidents are due to the interaction between individual, technical and organisational factors.
The target is thus the study of people at work from a cognitive systems engineering and socio-technical systems perspective.
The most relevant working contexts of interest to CTW are those where the impact of modern technologies on people at work is particularly important for the users involved as well as for the effects on the environment and plants. Modern society has come to depend on the safe and efficient functioning of a multitude of technological systems as diverse as industrial production, transportation, communication, supply of energy, information and materials, health and finance.
