Low-Frequency Noise: Experiences from a Low-Frequency Noise Perceiving Population. [PDF]
Int J Environ Res Public Health, 2023 Although low-frequency noise (LFN) is associated with various complaints, there is still much unknown about this phenomenon. This research aims to provide an extensive description of (1) LFN perceptions, (2) LFN-related complaints, and (3) the characteristics of LFN complainants. In an explorative observational cross-sectional survey study, a sample of

Correcting Low-Frequency Noise with Continuous Measurement [PDF]
Physical Review Letters, 2007 Low-frequency noise presents a serious source of decoherence in solid-state qubits. When combined with a continuous weak measurement of the eigenstates, the low-frequency noise induces a second-order relaxation between the qubit states. Here we show that the relaxation provides a unique approach to calibrate the low-frequency noise in the time-domain ...

Nature of low-frequency noise in homogeneous semiconductors. [PDF]
Sci Rep, 2015 AbstractThis report deals with a 1/f noise in homogeneous classical semiconductor samples on the base of silicon. We perform detail calculations of resistance fluctuations of the silicon sample due to both a) the charge carrier number changes due to their capture–emission processes and b) due to screening effect of those negative charged centers and ...

Measuring low-frequency noise indoors [PDF]
The Journal of the Acoustical Society of America, 2008 At low frequencies, the sound pressure level may vary 20-30 dB in a room due to standing waves. For assessment of annoyance, mainly areas with the highest occurring levels are relevant, since persons present in such areas are not helped by the existence of lower levels in other areas.

Characterizing Low-Frequency Qubit Noise
Physical Review Applied, 2023 Fluctuations of the qubit frequencies are one of the major problems to overcome on the way to scalable quantum computers. Of particular importance are fluctuations with the correlation time that exceeds the decoherence time due to decay and dephasing by fast processes. The statistics of the fluctuations can be characterized by measuring the correlators

Low frequency noise in Josephson junctions [PDF]
IEEE 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^{

Map of low‐frequency electromagnetic noise in the sky [PDF]
Geophysical Research Letters, 2015 AbstractThe Earth's natural electromagnetic environment is disturbed by anthropogenic electromagnetic noise. Here we report the first results from an electromagnetic noise survey of the sky. The locations of electromagnetic noise sources are mapped on the hemisphere above a distributed array of wideband receivers that operate in a small aperture ...
