Recently, it was performed using both acoustical waves and array processing algorithms in order to improve depth range and spatial resolution.
In order to cancel the acoustical echo efficiently, various processing architectures including fixed filters, hybrid processors, and sub-band structure are investigated.
These "speech-selective" effects might be driven by regions' intrinsic biases for processing the acoustical or informational properties of speech.
Our findings confirm a functional organization of auditory cortex in which higher stages of cortical processing integrate acoustical features extracted by lower levels of cortex into more complex representations [ 30].
A space-frequency processing of the acoustical signals given by the array then enables one among other things to evaluate the acoustical energy radiated by the area considered, in a given octave band.
To simulate motion, the speed and trajectories are crucial to creating realistic acoustical environments, and developing signal processing methods for reconstructing these contexts is a great challenge.
Age-related difficulties in gap detection more likely occur at a later stage of processing where the acoustical properties of the stimulus are bound together to form an auditory object.
In fact, data of the present study evidence that the middle and posterior auditory cortex especially of the left hemisphere is significantly involved in the processing of the acoustical features critical for the processing of temporal cues in both speech and non-speech sounds.
Rapid advancements in acoustical beamforming techniques for array signal processing are producing algorithms with increased levels of computational complexity.
Perceiving and processing these two complex acoustical signals rely on a hierarchical functional network distributed throughout several brain regions within and beyond the auditory cortices.
Geometric or acoustical irregularities induces acoustic scattering.
