Relations between points of 51ユbjective equality ( PSE )and ム 。q for loudness, an . noyance and endurance of road tra缶 c noise exposed during the works were i胛 esti − gated, and e 任ects of vibration on these subjective r且 tings of road traf 五c noise were also investigated . Eight male students were adopted as subjects . Road traMc noise ( T ) were exposed at 51evels from 60 to 80 dBA ,ム。 q . Vibration was exposed vertically in whole body at 75 dB 、 VL ( energy mean > overlapping road traf丑c

Control experiments were also made . using pink noise at 71evels from 50 to 80 dBA , background noise of 42 dBA , L . g and background noise of 58 dBA , L 。 q in concomitance with vibration ( P , B 。, B ユ( V ) ) . As a result of experiments , subjective ratings mentioned above had the linear relation with noise levels of T , T ( V ) and P respectively . Then , PSEs of tra伍 c noise were calculated for these subjective ratings respectively . It was found that PSEs of loudness . annoyance and endurance of tra{ 丑c noise were lower than L 。q . Vibration tended to a 鉦ect to subjective ratings of road tra 伍 c n6ise in the lower levels. Further, present data were compared with those of experiments and commu − nity responses of other researchers . 1. は し が き
