A three-year study is reported of the nature and influence of the transmission of vibratory energy from a hand tool to an operator's hand; the attendant vibratory acceleration levels and the transmissibility from hand tool to various locations on the operator's hand and arm; the factors influencing an individual's subjective response to hand arm vibration; and the physiological mechanisms involved with regard to subjective response to vibration. Results show that the mechanical and subjective response characteristics of individuals to hand vibration were a function of the manner of clasping the vibratory tool handle and the orientation of the vibration relative to the hand. The vibration response of the hand was indicative of only local response characteristics of the hand and fingers. Attenuation of vibration as it proceeded up the arm occurred in the tissue adjacent to bone and not the bone itself; similarly, there was little attenuation across the joints. The results of subjective response tests indicate that Ruffini endings, joint capsules, and Meissner's corpuscles were responsible for subjective response to low frequency (equal to or less than 100 hertz) discrete frequency hand induced vibration, whereas Merkel's discs, Ruffini endings, and pacinian corpuscles were responsible for subjective responses above 100 hertz (discrete frequency vibration). Broad band vibration was subjectively determined mainly from the response characteristics of tonic receptors. Salient findings indicate a questionable credibility with regard to using subjective response data for the purpose of establishing hazardous hand- vibration criteria. It can also be inferred from the results that high frequency vibration (above 100 hertz) is responsible, in part, for the destructive effects associated with vibration syndrome.
