Abstract

Noise pollution is a critical concern on construction sites because it adversely affects the cognitive performance of workers. While prior research has explored the effect of construction noise on workers’ cognitive performance, gaps remain in understanding how these effects change under varying task difficulty and noise frequency. To address this limitation, this study investigates the combined effects of construction noise frequency and task difficulty on mental workload using EEG. To this end, a 3-level N-back memory task was conducted under three noise conditions while EEG data of participants was recorded simultaneously. Furthermore, behavioral and subjective data were collected. This study found that low-frequency noise has a more negative impact on mental workload. The frontal and left occipital-parietal brain regions show more responses to changes in mental workload. This study is expected to help in the development of mental workload assessment models and construction noise regulations for safety interventions.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
