Low-frequency band noise generated by industrial recirculating aquaculture systems exhibits a greater impact on Micropterus salmoidess

Ecotoxicology and Environmental Safety
The effect of underwater noise environment generated by equipment in industrial recirculating aquaculture systems (RAS) on fish is evident. However, different equipment generate noise in various frequency ranges.

Development of an on-site system for measuring the low-frequency noise and complainant’s responses

Journal of Low Frequency Noise, Vibration and Active Control, 2018
An on-site system for measuring low-frequency noise and complainant's responses to the low-frequency noise was developed to confirm whether the complainant suffer from the environmental noise with low-frequency components.

Health-based Audible Noise Guidelines Account for Infrasound and Low Frequency Noise Produced by Wind Turbines

Frontiers in Public Health, 2015
Setbacks for wind turbines have been established in many jurisdictions to address potential health concerns associated with audible noise. However, in recent years it has been suggested that infrasound (IS) and low frequency noise (LFN) could be ...

Low-Frequency Ambient Noise Cutoff [PDF]

The Journal of the Acoustical Society of America, 1972
There have been very few measurements of ambient noise levels at frequencies below 1 Hz. These measurements show the ambient level to increase steadily with decreasing frequency. Does this trend persist or is there some frequency below which the ambient level no longer increases or actually decreases with frequency?

Noise Characteristics of ±800 kV HVDC Convert StationBased on Spectrum Analysis

Zhongguo dianli, 2019
By collecting the sound pressure signals of the aerodynamic noise of the converter transformer fans, the electric field noise of the smoothing reactors and the electric field noise of the DC/ AC filter field in the 800 kV converter station, the spectrum ...

1/f noise of Josephson-junction-embedded microwave resonators at single photon energies and millikelvin temperatures

, 2011
We present measurements of 1/f frequency noise in both linear and Josephson-junction-embedded superconducting aluminum resonators in the low power, low temperature regime - typical operating conditions for superconducting qubits.

Effect of luminance noise on the object frequencies mediating letter identification

Frontiers in Psychology, 2014
Purpose: To determine if the same object frequency information mediates letter contrast threshold in the presence and absence of additive luminance noise (i.e. noise-invariant processing) for letters of different size.

Ramanujan sums for signal processing of low frequency noise

, 2002
An aperiodic (low frequency) spectrum may originate from the error term in the mean value of an arithmetical function such as M\"obius function or Mangoldt function, which are coding sequences for prime numbers.
