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

Extensive hearing loss induced by low‐frequency noise exposure [PDF]

Laryngoscope Investigative Otolaryngology, 2022
Background With little attention given to low‐frequency traffic noise and our understanding that cochlear function may be highly susceptible to low‐frequency noise, there is an urgent need to determine traffic noise‐induced hearing loss (NIHL), not only ...

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 ...

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 Si and Si/SiGe/Si PMOSFETs

Journal of Telecommunications and Information Technology, 2023
Measurements of 1/f noise in Si and Si0.64Ge0.36 PMOSFETs have been compared with theoretical models of carrier tunnelling into the oxide. Reduced noise is observed in the heterostructure device as compared to the Si control.
