“…6 Thus, EEG studies using infrasound stimuli often apply an analysis in the frequency domain. Kasprzak 7 investigated the influence of narrow-band signals with frequencies between 4 and 8 Hz on α -waves in EEG signals. Kolesnik et al 8 investigated the correlation between infrasound exposure events and the time-development of various bands of EEG signals.…”

Concerns about potential health risks from infrasound exposure require objective investigation methods for the perception of infrasound by humans. Neural-network methods were applied to identify weak infrasound evoked potentials and to investigate the efficacy of these techniques. Two simple networks – a fully connected three-layer feed-forward network and a two-layer autoencoder – were designed for the analysis of electroencephalography (EEG) data recorded in response to infrasound stimuli presented. Late auditory evoked potentials (LAEPs) were detected and correlation factors between the target and the output of the networks were determined to assess the differentiation ability of the two networks. Both networks were able to differentiate infrasound evoked potentials from noise but showed different performance levels with respect to a differentiation threshold. The results can be applied to objectively identify perception events by infrasound in humans.

The purpose of this paper is to determine the eect of infrasound noise from wind turbines (up to 20 Hz) on the changes in the EEG signal patterns in humans. The experimental study was undertaken to investigate the eect of a 20 minutes long infrasound exposure on humans. The acoustic signal was recorded at a distance of 750 meters from the wind turbine and the frequency components above 20 Hz were then ltered out. Research work undertaken so far to investigate the impacts of wind turbine noise on humans would mostly rely on questionnaire tools and subjective assessment given by respondents. This study focuses on the eects of infrasound noise from wind turbines on variations of EEG signal patterns in an attempt to develop a more objective measure of the infrasound noise impacts. The experimenal study was conducted in a pressure cabin where the EEG procedure was performed. Analysis of the EEG signals reveals the changes between the EEG patterns registered during the three successive stages of the study.The results indicate some changes in EEG signal patterns registered under exposure to wind turbine noise. Moreover, the specic frequency ranges of the EEG signals are found to be altered.

The problem of low-frequency acoustic waves emitted by wind turbine farms has become a great challenge to acousticians in Europe for more than 20 years. In Poland wind farm industry is growing rapidly and generates questions about the inuence of such sounds on human organism. A short survey of previously published reports concerning subjectively perceived inuence of wind turbines on people living next to wind farms is given together with the results of the Thayer's test measuring the dierence in activation level before and after exposition on infrasound wave generated by a wind turbine. Statistically signicant increase of the High Activation Level representing a tension type arousal has been revealed.
