Effects of aging on spatial hearing

Aging Clinical and Experimental Research, 2019
Aging has several effects on auditory processing with the most important effect known as speech perception impairment in noise.The aim of the present study was to investigate the effects of aging on spatial hearing using quick speech in noise (QSIN) and binaural masking level difference (BMLD) tests and speech, spatial, and qualities of hearing scale ...

Effectiveness of spatially-variant apodization

Proceedings., International Conference on Image Processing, 2002
Sidelobe artifact is a common problem in image reconstruction from finite-extent Fourier data. Conventional shift-invariant windows applied to the Fourier data, reduce sidelobe artifacts at the expense of worsened mainlobe resolution. Stankwitz et al.

Spatial multistability and nonvariational effects

Physical Review E, 1999
We investigate the phenomenon of spatial multistability of fronts in thin bistable systems and stress the important role played by the absence of a variational principle. Nonvariational effects allow, for instance, two different immobilized fronts to coexist.

Spatial correlation effects in a laser

Physical Review A, 1996
Spatial correlation effects are analyzed in a laser near and below its threshold of oscillation by integrating the modifications in the correlation function of intensity fluctuations and related parameters. The pump parameter of the laser is shown to depend on the field spatial coherence which arise due to transverse-mode structure of the laser field ...

The Effect of Barriers on Spatial Representations

Child Development, 1981
48 first graders and 48 fifth graders learned the arrangement of 6 objects in a novel environment containing 2 large barriers. 3 nonoverlapping paths, each connecting all locations, were devised. Children were assigned to 4 experimental conditions representing the factorial combination of number of trials of walking (2 vs.

An oblique effect of spatial summation

Vision Research, 1983
Contrast thresholds for sinewave gratings were measured as a function of the number of cycles in the grating for two different orientations and three spatial frequencies. At high spatial frequencies, where an oblique effect of contrast sensitivity was demonstrated, there was a greater increase in contrast sensitivity as a function of the number of ...
