A Comparative Study of Mode Arrivals at Megameter Ranges for 28 Hz, 75 Hz, and 84 Hz Sources
At long range, the low order acoustic modes constitute some of the most energetic arrivals. Prior to using these signals in tomographic or matched field inversions, it is important to understand their fluctuation statistics. Long vertical line arrays installed as a part of the Acoustic Thermometry of Ocean Climate (ATOC) experiment provided a unique opportunity to measure low-order acoustic mod...
متن کامل20 Hz rhythm of activity
Cats attended to either visual or acoustic moving stimuli in order to perceive the location of their disappearance, which signaled reward in left or right foodwell. The analysis of concomitant electroencephalograms revealed an elevation of the 20 Hz band in the Fourier spectra of activity of respective visual and auditory projection cortices. These oscillations appeared only on the trials that ...
متن کاملHz Event Related Auditory Potential
Main focus of this paper is an EEG experiment on observing frequency of event related auditory potential in response to series of clicks. Based on the past research, it was expected to observe 40 Hz potential, which was not the case. The experiment was conducted on one subject, and the average observed frequency of 61 Hz could be explained by individual differences. However, an additional step ...
متن کامل20 Hz bursting beta activity
It has recently been found (Bekisz and Wróbel 1993) that electroencephalographic recordings from the primary visual cortex and lateral geniculate nucleus of cats attending to visual stimuli contained enhanced activity in the 20 Hz frequency band. Here we present the detailed analysis of this activity. It consisted of short (0.1-1 s) bursts of oscillations which tended to appear simultaneously i...
متن کاملSyllabic (∼2-5 Hz) and fluctuation (∼1-10 Hz) ranges in speech and auditory processing.
Given recent interest in syllabic rates (∼2-5 Hz) for speech processing, we review the perception of "fluctuation" range (∼1-10 Hz) modulations during listening to speech and technical auditory stimuli (AM and FM tones and noises, and ripple sounds). We find evidence that the temporal modulation transfer function (TMTF) of human auditory perception is not simply low-pass in nature, but rather e...
