A Proposal for Risk Assessment of Low-Frequency Noise in the Human–Machine–Environment System

open access: yesApplied Sciences, 2023
Low-frequency noise, the frequency range from approximately 10 Hz to 200 Hz, has been recognized as a special environmental noise problem. The World Health Organization recognizes the special place of low-frequency noise as an environmental problem ...

Constant and switched bias low frequency noise in p-MOSFETs with varying gate oxide thickness [PDF]

open access: yes, 2002
The low-frequency noise power spectral density of MOSFETs is decreased if the MOSFETs are periodically switched 'off' (switched bias conditions). The influence of the gate oxide thickness on fixed bias and switched biased low frequency drain current ...

Low frequency noise in Josephson junctions [PDF]

open access: yesIEEE Transactions on Magnetics, 1975
Using a high resolution SQUID voltmeter, we have measured the spectrum of low frequency voltage fluctuations across a thin-film Josephson tunnel junction biased at a constant current I greater than the junction critical current I c . We find that the frequency dependence of the voltage spectrum V^{2}(f) may be accurately represented by the power law V^{

The X-ray fast-time variability of Sco X-2 (GX 349+2) with RXTE [PDF]

open access: yes, 2001
Sco X-2 (GX 349+2) is a low-mass X-ray binary and Z source. We have analysed 156 ks of Rossi X-ray Timing Explorer data, obtained in 1998 January, on this source. We investigated the fast-time variability as a function of position on the Z track.

Active noise cancellation of low frequency noise propagating in a duct

open access: yesInternational Journal of Environmental Health Engineering, 2012
Aims: The object is to find a manner of reduction primary noise from a source by an electro acoustic device that cancels unwanted sound by generating an anti sound (anti noise) of equal amplitude and an opposite phase is described as an active noise ...

Effect of personality traits on sensitivity, annoyance and loudness perception of low- and high-frequency noise

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
This paper presents investigations into a comparative assessment of the effects of low- and high-frequency noise in relation to personality traits. The high- and low-frequency noises used are produced in the research laboratory using CoolEdit software ...

Low Frequency Noise Annoyance Assesment by Low Frequency Noise Rating (LFNR) Curves

open access: yesJournal of Environmental Conservation Engineering, 1983
Over recent years, it has become apparent that low frequency noise annoyance is more widespread than originally believed. Annoyance has occurred where the emitted noise is unbalanced towards the low frequencies even though the dB(A) level has been low.
