Cross correlation of ambient seismic noise between four seismographs on tabular iceberg C16, Ross Sea, Antarctica, reveals both the source and the propagation characteristics of signals associated with icebergs. We find that noise correlation functions computed from station data are asymmetric about zero time lag, and this indicates that noise observed on the iceberg originates primarily from a...

Noise pollution of roads can propagate within a broader extent than the road only. This spatial space is called "road ecological effect zone" which is known as the natural areas exposed by 40 dB or greater noise level in both sides of the road. In this study, using Calculation of Road Traffic Noise (CRTN) model, the propagation range of noise from Lorestan road network was simulated. Then, the ...

Introduction: Noise is one of hazardous agents of workplaces in industries. Electric industries and power plants are among industries in which noise pollution should be taken into account. This study aimed to develop and verify a statistical model for acoustic wave propagation in an indoor environment for noise related risk reduction management. . Material and Method: This theoretical-experime...

We consider noise-assisted spike propagation in myelinated axons within a multicompartment stochastic Hodgkin-Huxley model. The noise originates from a finite number of ion channels in each node of Ranvier. For the subthreshold internodal electric coupling, we show that (i) intrinsic noise removes the sharply defined threshold for spike propagation from node to node and (ii) there exists an opt...
