background: noise pollution can contribute to adverse health effects in humans. noise annoyance and related problems, caused by noise emission during the progress of building construction, have become increasingly important. these problems can influence the exposed workers, as well as vicinity residents. the goal of the present study was to assess the noise annoyance due to noise from construct...

We introduce information-theoretic definitions for noise and disturbance in quantum measurements and prove a state-independent noise-disturbance tradeoff relation that these quantities have to satisfy in any conceivable setup. Contrary to previous approaches, the information-theoretic quantities we define are invariant under the relabelling of outcomes and allow for the possibility of using qua...

In this paper, we propose a feedback active noise control (ANC) system which can surpress disturbance. The conventional feedback ANC system has a possibility of divergence because the disturbance of broadband noise corrupts the input signal for the system. To surpress the disturbance, we incorporate a linear prediction filter into the feedback ANC system. Simulation results show that the propos...

electric wheelchairs (ew) experience various terrains surfaces and slopesas well asoccupants with diverse weights. this, in turn, imparts a substantial amount of perturbation to the ewdynamics. in this paper we make use of a two-degree-of-freedom control architecture called disturbance observer (dob) which reduces sensitivity to model uncertainties while enhancing rejection of disturbances caus...

There is a lack of studies assessing the exposure-response relationship between transportation noise and annoyance in North America. Our aims were to investigate the prevalence of noise annoyance induced by road traffic, trains and airplanes in relation to distance to transportation noise sources, and to total environmental noise levels in Montreal, Canada; annoyance was assessed as noise-induc...

environmental noise pollution is among the most urban problems which can be caused due to real sources like traffic, train and virtual sources provided by rigid surfaces. one of the urban structures in which can perform as a virtual noise source are the installed gutters alongside highways. these structures are mostly used to pass the wastewater or the rainfall. in this research, the acoustical...

UNLABELLED Factors modifying the effect of environmental noise on sleep include sex, age, susceptibility, personality and the health status, including past and present history of disease. OBJECTIVE The effects of noise on sleep and habituation of sleep to noise were summarized. RESULTS AND CONCLUSIONS 1) The effect of noise on sleep is associated with physical changes, such as changes in he...
