BREAKING DOWN 'Tight Monetary Policy'. The Fed can sell Treasuries on the open market in order to absorb some extra capital during a tight monetary policy. This effectively takes capital out of the open markets as the Fed takes in funds from the sale with the promise of paying the amount back with interest. The Fed will often look at tightening monetary policy during times of strong economic growth.
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.
