Auditory search asymmetry

Auditory search asymmetry between normal Japanese speech sounds and time-reversed speech sounds distributed on the frontal-horizontal plane

“…Moreover, the present authors introduced spatial distribution and conducted auditory search experiments with pure tone and temporal fluctuating sounds under conditions where each component sound came from a different direction [6]. They obtained results comparable to those of Sugita et al [5], namely, that a temporal fluctuating sound pops out from among pure tones and concluded that temporal fluctuation may be regarded as a feature causing pop out.…”

“…Cusack and Carlyon [4] found that a frequency modulated tone popped out from sequentially and monaurally presented pure tones due to frequency modulation. Sugita et al [5] reported an auditory search asymmetry between pure tones and temporal fluctuating sounds (narrow band noises, frequency-modulated tones and amplitudemodulated tones) under monaural and simultaneous listening conditions. Moreover, the present authors introduced spatial distribution and conducted auditory search experiments with pure tone and temporal fluctuating sounds under conditions where each component sound came from a different direction [6].…”

THE CATALYTIC PERFORMANCE OF Mg-A1 CATALYST IN TRANSESTERIFICATION OF GLYCEROL WITH ETHYLENE CARBONATE

“…Mouloungui et al (1996) patented a process for the manufacture of GC by reacting glycerol with propylene carbonate in the presence of solvent and using zeolites as catalyst. Studies by Sugita et al (1994) reported that the synthesis of GC using aluminum oxide (Al 2 O 3 ) as catalyst was conducted under reduced pressure and mild temperature around 140°C. Wheres Vieville et al (1998) used zeolite catalyst at 80°C with two molar ratio of ethylene carbonate to glycerol to give the desired GC.…”
