Infrasound, Its Sources and Its Effects on Man

摘要: Abstract : Infrasound, sinusoidal pressure variations from 0.1 to 20 Hz, is somewhat more complicated measure and analyze than sound of higher frequency. But the most common error in analyzing infrasound not also frequency sounds then interpret these with respect their effects on humans. Generally, where there intense infrasound, are above Hz; that cause adverse human effects. At sufficient intensity audible, but easily masked by sound. Infrasound does often occur at levels harmful or even audible man. Thus exposure one mankinds pressing environmental problems.
