A questionnaire-based study was performed in an area of about 16 ha near a main road in Tokyo to elucidate any relations between road traffic noise and the effects of this noise among women living on both sides of the road. Questions concerned annoyance, sleep disturbance, interference with daily ac
This study was designed to assess the e!ects of road tra$c noise and frogs' croaking on the objective and subjective quality of sleep in a laboratory. The subjects were seven male students aged 19}21 years. They were exposed to recorded road tra$c noise and frogs' croaking, with 49)6 and 49)5 dB(A)
Turbulence caused by train motion, heat radiation and wind eddies destroys the coherent nature of the ground effect. Due to upward refraction, only a certain segment of the track contributes to noise emission. Thus, geometrical spreading and refraction govern the process of noise propagation. Noise
