title: Evaluation of whole-body road traffic vibration in building.
abstract: Level fluctuating vibration has been evaluated by the cumulative index L10, but some investigators suggest that the L10 cannot represent an adverse comment on vibration. In order to clarify the compliant, various factors involving vibration need to be analysed together by statistical methods, for instance factor analysis or quantum theory. The authors investigated the relationship between an evaluation index and human sensation of vibration in a subjective experiment in a wooden house. The subjects were exposed to vertical road traffic vibration reproduced with an electrodynamic vibrator placed near the house. The range of vibration levels at surfaces in contact with the subjects were from 50dB to 70dB in root mean square of frequency weighted acceleration level, i.e. the vibration level. Numbers assigned by the subjects and evaluation indices of the vibration level were analysed by applying the Stevens power law. The results showed that L10 or Leq (55) could become an effective index for the assessment of subjective perception of level fluctuating vibration in a wooden house.
