METHODOLOGICAL CONSIDERATIONS IN THE STUDY OF HUMAN DISCOMFORT TO VIBRATION

Statement and discussion of vibration discomfort tests carried out with the NASA's Passenger Ride Quality Apparatus (PRQA). A random sample of 60 subjects were subjected, over a period of time, to sinusoidal frequencies from 0 to 20 Hz with 0.05 g to 0.25 g amplitudes. The paper explains the test equipment used, the method adopted to measure discomfort, the discomfort levels evaluated according to this method and their various correlations. The results are summarized into seven well-defined conclusions relating to the influence of frequencies and accelerations, of the floor or seat level at which the accelerations are measured, of the previous experience of the subjects, and their personality.
