how does frequency affect draw
The erroneous assumption made by this committee was that effects of low frequency sound can only be mediated through hearing, so that if infrasounds could not be heard then they could not possibly affect human physiology. Such an assumption is absurd and does not apply to other sensory systems of the body.t is also known that OHC provide mechanical amplification of the high frequency sounds that you normally hear. The presence of low frequency sound can alter the amplification of high frequency sounds which causes amplitude modulation and harmonic distortion of the high frequency sounds.
