Sixteen subjects were exposed for three hours to inaudible infrasound, audible infrasound, traffic noise and a quiet control condition, while they performed various psychological tasks. Some cardiovascular and hearing parameters were recorded and after the experiments the subjects answered a questionnaire concerning their experiences during the noise exposure.The most conspicuous effect of infrasound was a high rating of annoyance and a feeling of pressure on the ear at less than 20 dB above the threshold of hearing. No influence on the cardiovascular system was seen and the performance only deteriorated in one of nine tasks. lnfrasound below the threshold had no effect.It is concluded that a better knowledge of the hearing at low frequencies is required, the most urgent being an extension downward in frequency of existing curves of equal loudness and equal annoyance.

“…Lower-frequency (\40 Hz) mechanical energies have the capacity to affect the semicircular canals (primarily associated with balance), the otolith system, chest and abdominal cavities, and the whole body. The three pairs of semicircular canals and the otolith structures are most sensitive to infrasound frequencies around 7 Hz (Evans and Tempest 1972). These otolith and semicircular canals are particular sensitive to linear and angular acceleration of the head, respectively.…”

“…Bruel and Olesen (1973) found that artificial generation of infrasound around 12 Hz within the 85-110 db range elicited ill-feelings within a few seconds in several people. While infrasound pressures between 115 and 120 db generated between 1 and 20 Hz did not produce visual anomalies during routine test-taking behaviors, there was a 30-40 % increase in reaction time as well as the sensation of lethargy (Evans and Tempest 1972). Application of whole-body vibrations from vertically applied sinusoidal variations displays maximum transmissibility around 5-6 Hz with a range between about 3 and 7 Hz (Stephens 1969).…”

Infrasound displays a special capacity to affect human health and adaptation because its frequencies and amplitudes converge with those generated by the human body. Muscle sounds and whole-body vibrations are predominately within the 5-to 40-Hz range. The typical amplitudes of the oscillations are within 1-50 lm, which is equivalent to the pressures of about 1 Pa and energies in the order of 10 -11 W m -2 . Infrasound sources from the natural environment originate from winds, microbaroms, geomagnetic activity, and microseisms and can propagate for millions of meters. Cultural sources originate from air moving through duct systems within buildings, large machinery, and more recently, wind turbines. There are also unknown sources of infrasound. It is important to differentiate the effects of infrasound from the awareness or experience of its presence. Moderate strength correlations occur between the incidences of infrasound and reports of nausea, malaise, fatigue, aversion to the area, non-specific pain, and sleep disturbances when pressure levels exceed about 50 db for protracted periods. Experimental studies have verified these effects. Their validity is supported by convergent quantitative biophysical solutions. Because cells interact through the exchange of minute quanta of energy that corresponds with remarkably low levels of sound pressure produced by natural phenomena and wind turbines upon the body and its cavities, traditional standards for safety and quality of living might not be optimal.
