Appraisal of environmental noise effects on health considers single exposure. In large cities, exposure is frequently due to multiple sources. Their combination, interaction or successive presence known affect people’s health. The prediction their has been little studied and needs more investigation address the problem. Studies dealing with annoyance combined sources proposed different total mo...

Various studies indicate that at the same noise level and during the daytime, annoyance increases in the order of rail, road, and aircraft noise. The present study investigates if the same ranking can be found for annoyance to nocturnal exposure and next day cognitive performance. Annoyance ratings and performance change during combined noise exposure were also tested. In the laboratory 72 part...

Classical models for predicting annoyance due to combined noise and vibration have typically taken the form of a summation of the magnitudes of the individual stimuli. In this paper, the perception of combined railway noise and vibration will be investigated as a complex multidimensional phenomenon. In a laboratory study, 30 subjects were exposed to 10 combined railway noise and vibration stimu...

In this paper, we propose an efficient integrated acoustic echo and noise suppression algorithm using the combined power of acoustic echo and background noise within a soft decision framework. The combined power of the acoustic echo and noise is adopted to the integrated suppression algorithm based on soft decision to address the artifacts such as the nonlinear distortion and the disturbed nois...

Background: Noise and vibration are environmental pollutants that endanger people’s productivity sleep quality in ships, but the coupled effect ship cabins has not been studied. This study aimed to assess of noise propose a comfortable range vibration. Methods: Three different accommodation were chosen measure levels investigate their satisfaction. A revised model combining exponential membersh...
