简要总结
Study of noise generated by military-type aircraft and equipment maintenance in relation to non-auditory effects that impact with the body of the crew and ground staff can cause cardiac pathologies
Hypothesis of work: The pilots and the technical personnel of maintenance that work before the exhibition of noise generated by planes hunt F-16, or equipments of maintenance of the same ones, present major risk of a cardiac affectation, which demonstrates in changes in the normal pace of the heart, in his function of bomb or in hemodynamic conditions.
详细描述
The work area military airport is characterized by low frequency noise in sound pressure levels exceeding 100 dB, smashing into the body of pilots and ground staff.
It found variations in the thickness of the pericardium and deviation measures ejection fraction
