Low-frequency noise: Experiences from individuals reporting LFN complaints

Until now, Low-frequency noise (LFN) is hardly recognized as an environmental stressor, and its consequences on daily functioning have been rarely investigated. LFN is predominantly produced by human-made sources, and due to the increasing industrialization, these sources and accordingly the number of LFN complaints is steadily rising. Although the majority of the general population does not consciously perceive LFN, an estimated 2% of the Dutch adult population experiences severe annoyance from its exposure. Individuals sensitive to perceiving LFN in their everyday life report various physical complaints and particularly psychological complaints, such as sleeping difficulties, fatigue and stress, and cognitive difficulties such as difficulties in concentration or so-called executive functions. Yet, it is unclear why some people are more sensitive to and suffer more from LFN than others, and a comprehensive (neuro)psychological investigation in this population is still lacking. During an exploratory study, the demographic and personal characteristics of LFN-sensitive individuals, the perceptions of LFN-sensitive individuals and the reported physical, psychological, and social health-related symptoms and restrictions in daily living were investigated.
