The effects of environmental and classroom noise on the academic attainments of primary school children [PDF]
Journal of the Acoustical Society of America, 2008 While at school children are exposed to various types of noise including external, environmental noise and noise generated within the classroom. Previous research has shown that noise has detrimental effects upon children?s performance at school ...

Acoustical barriers in classrooms: the impact of noise on performance in the classroom [PDF]
, 2006 There is general concern about the levels of noise that children are exposed to in classroom situations. We report the results of a study that explores the effects of typical classroom noise on the performance of primary school children on a series of ...

Optimization of a Third-Order Gradiometer for Operation in Unshielded Environments [PDF]
, 2005 The optimum geometry of a third-order gradiometer for operation in unshielded environments is discussed. The optimization result depends on the specific signal and noise conditions. The fetal heart is considered as an example of the signal source.

Regression of Environmental Noise in LIGO Data [PDF]
, 2015 We address the problem of noise regression in the output of gravitational-wave (GW) interferometers, using data from the physical environmental monitors (PEM).

Characterising a solid state qubit via environmental noise [PDF]
, 2003 We propose a method for characterising the energy level structure of a solid-state qubit by monitoring the noise level in its environment. We consider a model persistent-current qubit in a lossy resevoir and demonstrate that the noise in a classical bias

Particle and Fibre Toxicology, 2022 Background Respirable mineral particles represent a potential health hazard in occupational settings and ambient air. Previous studies show that mineral particles may induce cytotoxicity and inflammatory reactions in vitro and in vivo and that the ...

Clock transition by continuous dynamical decoupling of a three-level system [PDF]
, 2018 We present a novel continuous dynamical decoupling scheme for the construction of a robust qubit in a three-level system. By means of a clock transition adjustment, we first show how robustness to environmental noise is achieved, while eliminating drive ...
