Curves that relate the amplitude of the first heart sound to the P-Q interval have been obtained in 13 dogs with complete atrioventricular (AV) heart block. The amplitude was highest at a P-Q interval of approximately 0.05 second, became lowest at a P-Q interval of 0.13 second and continu...
The goal was to find the best correlate between electrophysiological and behavioral measures of TEM encoding and speech recognition. We combined the measurement of AMD-ACCs, AMFD-ACCs, and the ASSR to amplitude modulated pulse trains in a single 3-stimulus paradigm studied with a clinical EEG ...
TEMPORAL EFFECTS IN SIMULTANEOUS MASKING AND LOUDNESS. The intention of the research described was twofold. One purpose was to investigate the difference between threshold curves for tones masked by bands of no... Zwicker,Eberhard - 《Journal of the Acoustical Society of America》 被引量: 158发表...
The amplitude of the ER depends negatively on the rate of the stimulus presentation (Naatanen and Picton, 1987). The cortical P1/N1/P2 ERs show higher amplitude at slower event rates between 1 and 5 Hz (Sussman et al., 2008, Wang et al., 2008), and, dependent on the stimulus ...
Urban Chiguanco Thrushes sing less, the frequency of the entire song rises, and the amplitude increases as compared with extra-urban Chiguanco Thrushes. Understanding variations between dawn and dusk choruses could allow for a better interpretation of how some bird species cope ...
THE ACOUSTIC PARAMETERS OF STRESS IN RELATION TO SYLLABLE POSITION, SPEECH LOUDNESS AND RATE MICHAEL D. McCLEAN There is considerable evidence showing that the most consistent acoustic correlates of English stress are the increased magnitudes of fundamental frequency, duration, and amplitude of stressed...
calculations can made easier with RMS = amplitude / √2 LevelVoltage Note - Comparing dBSPL and dBA: There is no conversion formula for measured dBA values to sound pressure level dBSPL or vice versa. Also you cannot convert "dBA to volts" and vice versa. ...
and once in a large range (20, 50, 60, 68 and 80 dB). Concurently, evoked cortical responses to SO and 68 dB were recorded. The range markedly influenced the loudness estimations but no significant range-effect was found in the peak-to-peak amplitude of the Nt - P2 waves....
The relationship between annoyance and ACF parameters showed the following to be important for evaluating annoyance: sound energy Φ(0), variances of Φ(0) and the maximum ACF amplitude φ 1. In terms of SQ metrics, the important factors for evaluating annoyance were loudness and fluctuation ...
