This commentary presents a synthesis of interdisciplinary findings that illustrate the inadequacy of regulatory frameworks in addressing the affective components of residents' complaints about the noise. Regulatory frameworks rely solely on energy-based, single-number quantities; however, they inadequately capture the cognitive and emotional dimensions of impact noise exposure. Evidence reveals that conventional structural interventions address mid- and high-frequency attenuation, but low-frequency components of floor impact noise are primarily unmitigated. Physiological studies have also reported autonomic arousal and activation of the stress system, particularly among individuals who are sensitive to noise. Epidemiological evidence further indicates that noise sensitivity affects a substantial proportion of the general population and constitutes an independent risk factor for adverse health outcomes. Future noise criteria require psychoacoustically informed metrics that incorporate emotional valence and individual factors.
