Introduction There is an increase in the segments of the general population who complain about low frequency noise (LFN) in their homes or in their workplaces. These individuals often complain about similar sets of concurrent symptoms, and frequently attribute their ailments directly to LFN exposure. Oftentimes, however, the routine clinical evaluation of these individuals reveals no apparent dysfunction, and patients with persistent complaints are subsequently referred to psychology or psychiatry heath professionals. Objective The goal of this report is to put forth a clinical protocol that would objectively evaluate the extent of LFN- induced pathology that may be present in these individuals. Methods Based on prior studies, the scientific rationale for each non-invasive diagnostic test is provided, and evidence of its clinical pertinence is presented. Results When LFN-induced pathology is suspected, the clinical protocol should include an echocardiogram, P300 evoked potentials, brainstem auditory evoked potentials, lung function tests with respiratory drive test after CO2 inhalation, a neurological examination, brain MRI, and blood chemistry analysis. Conclusion By providing individuals who blame LFN for their physical ailments with objective diagnostic testing, cases of malingering can be eliminated, and real medical assistance can be provided to arrest the development of irreversible lesions caused by LFN exposure.
