The aim of this paper is to evaluate the impact of exposure to low-frequency noise in residential areas, where there are power poles and power lines, in the human auditory system. A methodology to assess discomfort due to the low-frequency noise as well as audiometric tests exclusively for the low frequencies is proposed. Two predominantly urban areas were defined in Northwest Portugal to test the methodology. An {\textquotedblleft}exposed{\textquotedblright} and {\textquotedblleft}unexposed{\textquotedblright} study was used; the first group was highly exposed to the source under study and the second had no record of exposure to high voltage lines. To develop the research, a methodology was used to assess the discomfort due to low-frequency noise using audiometric tests (based on ISO-8253-1/2010) to determine the hearing threshold for pure sounds and recorded sound, as well as cognitive tests (Mini-Mental State Examination{\textemdash}MMSE). The average hearing threshold for recorded sound of the eight individuals tested in the {\textquotedblleft}exposed{\textquotedblright} group was 51.3\ dB, ranging from 40 to 65\ dB, while the mean of the six subjects in the {\textquotedblleft}unexposed{\textquotedblright} group was 24.1\ dB, ranging from 20 to 30\ dB. Based on the results obtained, the {\textquotedblleft}exposed{\textquotedblright} group seems to be less sensitive to the low frequencies when compared to the {\textquotedblleft}unexposed{\textquotedblright} group. The methodology used is adequate for a subjective assessment of the discomfort due to low-frequency noise.
