A lateral angle tool for spatial auditory analysis
نویسنده
چکیده
A new method is presented for examining the spatial attributes of a sound recorded within a room. A binaural recording is converted into a running representation of instantaneous lateral angle. This conversion is performed in a way that is influenced strongly by the workings of the human auditory system. Auditory onset detection takes place alongside the lateral angle conversion. These routines are combined to form a powerful analytical tool for examining the spatial features of the binaural recording. Exemplary signals are processed and discussed in this paper. Further work will be required to validate the system, and to compare it against existing auditory analysis techniques.

Relation between Working Memory Capacity and Auditory Stream Segregation in Children with Auditory Processing Disorder
Background: This study assessed the relationship between working memory capacity and auditory stream segregation by using the concurrent minimum audible angle in children with a diagnosed auditory processing disorder (APD).Methods: The participants in this cross-sectional, comparative study were 20 typically developing children and 15 children with a diagnosed APD (age, 9–11 years) according to...
متن کاملResolution of lateral acoustic space assessed by electroencephalography and psychoacoustics
The encoding of auditory spatial acuity (measured as the precision to distinguish between two spatially distinct stimuli) by neural circuits in both auditory cortices is a matter of ongoing research. Here, the event-related potential (ERP) mismatch negativity (MMN), a sensitive indicator of preattentive auditory change detection, was used to tap into the underlying mechanism of cortical represe...

In this paper, the consequences of filled volume on the transient lateral dynamic and stabilities boundaries displacement of an articulated vehicle carrying liquid is investigated. First, a sixteen-degrees-of-freedom nonlinear dynamic model of an articulated vehicle is developed. Then, the model is validated by using TruckSim software. Next, the dynamic interaction of the fluid cargo with the v...
متن کاملInterpolation of Head-Related Transfer Functions
Using current techniques it is usually impractical to measure head-related transfer functions (HRTFs) at a spatial resolution that does not exceed the minimum audible angle, i.e. 1-2° for a source directly in front, by a considerable amount. As a result, measured HRTFs must be interpolated to generate a display in which auditory space is rendered smoothly. The spatial resolution at which it is ...
