The Effect of Music on Working Memory Performance in Noisy Simulated Open-Plan Offices: An Experimental Study

In open-plan office environments, irrelevant speech noise (ISN) is a common complaint among employees, leading to reduced performance. This study aimed to assess the impact of music on the working memory performance of individuals exposed to ISN in simulated open-plan offices. Additionally, we sought to examine any differential effects of music between male and female participants. In this experimental study, participants were selected through convenient sampling. Their working memory performance was evaluated using n-back (n=1, 2) tests conducted with software while they were exposed to irrelevant speech noise (ISN) alone and a combination of ISN and music. Sampling took place over one month during the spring season in the acoustic laboratory of the Faculty of Health in Shiraz, Iran. Thirty students, including 15 females, with an ags range of 18 to 38 (Mean=25.27, Standard Deviation=6.03), participated in the study. The results showed a significant increase in the accuracy of participants’ responses to both simple and difficult tasks of the n-back (n=1, 2) test when music was played compared to the ISNonly condition. However, there was no significant difference between the conditions regarding reaction times in the working memory test. In the present study, the inclusion of music, specifically “For Elise,” emerged as a crucial factor in enhancing working memory amidst the presence of open-plan office noise. This finding underscores the potential of utilizing music as an effective strategy for improving cognitive performance in such environments. Given its cost-effectiveness and simplicity of implementation, incorporating background music like “For Elise” can be recommended as a favorable method for mitigating the negative impacts of noise in open-plan offices.
