In recent years, the world of work has undergone profound changes that have a significant impact on the physical spaces where people work. In the case of offices, there has been a shift from individual offices to open-plan spaces in, capable of accommodating multiple workstations. This change, in addition to generating cost savings, has led to an entirely new way of experiencing the workplace, transitioning from a more private space to a collective one. Over the years, research has focused extensively on the subjective satisfaction levels of workers. In the field of acoustics, particular attention has been given to the detrimental effects of Irrilevant Speech Noise (ISN), a parameter that defines the level of noise generated by conversations among workers, phone calls, and other noises they produce.
