Perception and Reaction to Floor Impact Noise in Apartment Buildings: A Qualitative Approach

This study used grounded theory to understand how apartment building residents perceive and react to floor impact noise from upstairs. In-depth interviews with a heterogeneous group of 14 participants were conducted, and the acquired data were analysed to develop a conceptual model for describing perception and reaction to floor impact noise. It was found that floor impact noise had diverse sources, with the majority originating from footsteps. The participants negatively perceived the noise as annoying and disturbing, and sleep disturbance was reported the most frequently. Cognitive and avoidant coping strategies were initially adopted, and complaints were only thereafter registered if the noise persisted. It was also observed that exposure to the noise led to self-reported health problems and concerns. The developed conceptual model highlights potential intervention measures for controlling noise perception and reactions to floor impact noise.
