Effects of low frequency noise on sleep.

open access: yesNoise & health, 2004
Low frequency noise (20-200 Hz) is emitted by numerous sources in the society. As low frequencies propagate with little attenuation through walls and windows, many people may be exposed to low frequency noise in their dwellings. Sleep disturbance, especially with regard to time to fall asleep and tiredness in the morning, are commonly reported in case ...

Analysis of noise generated by wind turbines with reference to other low frequency noise sources and their possible impact on human health. [PDF]

open access: yesInt J Occup Med Environ Health
Objectives A problem currently faced in the assessment of human exposure to the external environment concerns sources of noise with significant energy found in the range of infrasound and low sound frequencies. This paper presents an analysis of selected

Low frequency noise and annoyance in classroom [PDF]

open access: yesNoise Notes, 2000
The most common method for noise assessment is the A-weighted sound pressure level. The question has been raised as to whether the frequency weighting with an A-filter gives a correct result when assessing the annoyance response to noise containing strong low frequency noise (LFN) components.

A Proposal for Risk Assessment of Low-Frequency Noise in the Human–Machine–Environment System

open access: yesApplied Sciences, 2023
Low-frequency noise, the frequency range from approximately 10 Hz to 200 Hz, has been recognized as a special environmental noise problem. The World Health Organization recognizes the special place of low-frequency noise as an environmental problem ...
