Determination of significant sources generating low-frequency noise in horizontal axis wind turbines
Several studies show that the Low-Frequency Noise (LFN) of wind turbines could have harmful effects on human health even when it is infrasound. In traditional classifications, the LFN of upwind turbines is referred only to steady thickness and steady loading sources, and the effect of vortices is considered negligible. In this study, the LFN of a horizontal axis wind turbine is simulated in win...
متن کاملHIGH FREQUENCY OPTICAL RECTIFICATION IN BULK GaAs AND ASYMMETRIC AlGaAs/GaAs QUANTUM WELLS
The mechanism of the huge optical recti cation (OR) in asymmetrical quantum wells (AQW) has been investigated at high frequencies (HF) obtained by short far infrared pulses generated by a free electron laser. The HF coupling into the fundamental mode of the traveling wave transmission line is tested using the bulk OR in GaAs. Whereas the observed signal clearly demonstrates the principle of our...
متن کاملSources and effects of low-frequency noise.
The sources of human exposure to low-frequency noise and its effects are reviewed. Low-frequency noise is common as background noise in urban environments, and as an emission from many artificial sources: road vehicles, aircraft, industrial machinery, artillery and mining explosions, and air movement machinery including wind turbines, compressors, and ventilation or air-conditioning units. The ...
متن کاملLow Frequency Noise from Transportation Sources
Low frequency noise (LFN) is common as background noise in urban environments and as an emission from many artificial sources: road vehicles, aircraft, industrial machinery, artillery and mining explosions, and air movement machinery including wind turbines, compressors, and indoor ventilation and air conditioning units (Tempest, 1976; Leventhall, 1988 from St Pierre and Maguire [1]). LFN may a...
متن کاملDouble quantum dots as detectors of high-frequency quantum noise in mesoscopic conductors
We propose a measurement setup for detecting quantum noise over a wide frequency range using inelastic transitions in a tunable two-level system as a detector. The frequency-resolving detector consists of a double quantum dot which is capacitively coupled to the leads of a nearby mesoscopic conductor. The inelastic current through the double quantum dot is calculated in response to equilibrium ...
