Reshaping workspace soundscapes: An in-depth analysis of ISO 22955 compliance and its influence on acoustic comfort and wellbeing - a case study

The prevalence of hybrid office landscapes is on the rise, eliciting concerns among users primarily due to noise and the challenge of balancing two conflicting acoustic activities: oral communication and concentrated individual work. This study investigates the interplay between acoustic comfort and wellbeing in an office setting, utilizing evidence-based data gathered through occupant surveys before and after a comprehensive renovation. Prior to the renovation, room acoustic calculations were performed to assess compliance with the acoustic parameters from the ISO 22955:2021: "Acoustic quality of open office spaces". The office was transformed, guided by a human-centric approach, from a predominantly enclosed layout into one that incorporates a blend of open-plan areas and closed rooms designed for meetings, concentrated work and phone calls. Room acoustic measurements were taken before and after the renovation that confirm compliance with ISO 22955. The results of the questionnaire indicate improvements in concentration, decision-making and contemplation, which corresponds well with acoustic parameter values achieved. Nevertheless, "disturbance of nearby conversations" was not reduced as expected. The research delves into the connection between the indoor acoustic environment and subjective experiences of health, well-being, and responses to noise disturbances, emphasizing the need for tailored acoustic design to optimize overall workplace experiences.
