The presentation reviews issues associated with low frequency sound—sources, human perception, typical levels, and effects on imaging systems. A set of infrasound criteria are presented which correlate imaging resolution with low frequency sound levels. Design features intended to mitigate infrasound generation and impact are discussed.
