Study on the effects of infra- and low frequency
sound on the sleep by EEG recordings.
Oil extraction experiments were performed by using low frequency
vibration experimental apparatus, conical flask, sands, surfactant solution etc.
From this Fourier Series decomposition, it is possible to define flicker in terms of low frequency
signal components that may be of health risk concern.
Advice from the Low Frequency
Noise Sufferers' Association could set you straight.
In this paper, DFB and Fabry-Perot (FP) laser performance are compared, demonstrating how low frequency
noise can be translated up to a higher modulation frequency, and how fiber dispersion enhances noise.
In this phenomenon, subjects recall high frequency words better than low frequency
words, while recognizing low frequency
words more accurately than high frequency words (Shepard, 1967).
The considerable and growing interest in the phenomena of low frequency
noise and vibration and their powerful effects on man, animals and the environment, spreads across several disciplines; studies of these topics are to be found at present in the periodical literature of acoustics, geophysics, architecture, civil and mechanical engineering, psychology and zoology.
