Active noise cancellation of low frequency noise propagating in a duct
International 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 ...

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^{

Low Frequency Noise in Tantalum Capacitors
Active and Passive Electronic Components, 1987 Noise has been measured in a number of biased solid tantalum capacitors at frequencies down to 0.01 Hz. The noise current was found to have a 1/f power spectrum, and the amplitude varied with the bias voltage with a law in the range 1st to 4th power ...

Low Frequency Noise Annoyance Assesment by Low Frequency Noise Rating (LFNR) Curves
Journal 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. Following laboratory experiments carried out as part of an investigation into low frequency annoyance,

Measurement of the low-frequency charge noise of bacteria
Physical Review E, 2022 Bacteria meticulously regulate their intracellular ion concentrations and create ionic concentration gradients across the bacterial membrane. These ionic concentration gradients provide free energy for many cellular processes and are maintained by transmembrane transport.

A detailed study of low-frequency noise complaints [PDF]
, 2008 From 203 cases of low-frequency complaints a random selection of twenty-one cases were investigated. The main aim was to answer the question whether the annoyance is caused by an external physical sound or by a perceived but physically non-existing sound,
