Contributions to N‐2‐4, N‐3‐4, N‐4‐4, θ‐2‐4, and θ‐3‐4 hemispheric sound reproduction technology

Hemispheric differences in amygdala contributions to response monitoring.

The amygdala detects aversive events and coordinates with the rostral anterior cingulate cortex to adapt behavior. We assessed error-related activation in these regions and its relation to task performance using functional MRI and a saccadic paradigm. Both amygdalae showed increased activation during error versus correct antisaccade trials that was correlated with error-related activation in th...

Right-hemispheric cortical contributions to language ability in healthy adults.

In this study we investigated the correlation between individual linguistic ability based on performance levels and their engagement of typical and atypical language areas in the brain. Eighteen healthy subjects between 21 and 64 years participated in language ability tests, and subsequent functional MRI scans measuring brain activity in response to a sentence completion and a word fluency task...

Spatial Hearing Mechanisms and Sound Reproduction

1. The time of arrival of the wave front of a sound event at the ears, or more specifically, the difference in arrival times at the two different ears. A sound source anywhere on a line from due front, through due above to due back (the median plane) will have its wave front arrive at the two ears simultaneously. Move the source away from this line and one ear will begin to receive the wave fro...

Binaural Hearing and Systems for Sound Reproduction

Robust reproduction of sound zones with local sound orientation.

Pressure matching (PM) and planarity control (PC) methods can be used to reproduce local sound with a certain orientation at the listening zone, while suppressing the sound energy at the quiet zone. In this letter, regularized PM and PC, incorporating coarse error estimation, are introduced to increase the robustness in non-ideal reproduction scenarios. Facilitated by this, the interaction betw...
