The investigation of human sensibility to vibration was conducted by a semantic differential method to clarify the relation between the vibration magnitude of a ship and human sensibility. VL is the most suitable vibration magnitude for the-vibration sensibility rating. The weighted overall vibration measurement method is superior to the Octave band boundary evaluation method in sensibility rating. VL is the physical amount of the vibration that is equivalent to the sound level in dB (A) in terms of the sound, and it's a dB value that is indicated through the network VL with a frequency response according to the weighting curve proposed by ISO. The relationship of the vibration level VL and the cartegory stage areas given below. "Indifferent" "Somewhat" "Considerably" "Very" VL(standing posture) 17dB 23dB 29dB 35dB VL(laying posture) 11dB 17dB 23dB 29dB
