Modelling Speech Intelligibility in Adverse Conditions
Fig. 38.1 Schematic of the short-term sEPSM. The noisy speech (black) and the noise alone (grey) are processed separately through the model. The decision metric is based on the time-varying…
Better Temporal Neural Coding with Cochlear Implants in Awake Animals
Psychophysical: human CI subjects Neural: IC neurons in anesthetized cats Percept lasts throughout stimulus >2,000 pps 30–300 ppsa Sustained responses Rate pitch discrimination 200–1,000 ppsb 40–200 ppsa Temporal coding ITD…
When and How Envelope “Rate-Limitations” Affect Processing of Interaural Temporal Disparities Conveyed by High-Frequency Stimuli
Fig. 30.1 Threshold ITD as a function of envelope-rate or noise bandwidth for stimuli centered at 4 kHz (upper panel) or 8 kHz (lower panel) (Adapted with permission from Bernstein…
High-Acuity Spatial Stream Segregation
Fig. 54.1 Rhythm discrimination by one listener. The dashed line at d′ = 1 indicates the criterion for threshold rhythm discrimination (From Middlebrooks and Onsan 2012) Acuity was somewhat coarser…
The Sound Source Distance Dependence of the Acoustical Cues to Location and Their Encoding by Neurons in the Inferior Colliculus: Implications for the Duplex Theory
Fig. 31.1 (a) Example rate vs ILD function. Distributions of half-max ILD (b), ILD dynamic range (c), and rate-ILD slope (d) for low (<4 kHz)- and high (>4 kHz)-frequency ICC…
Can Comodulation Masking Release Occur When Frequency Changes Could Promote Perceptual Segregation of the On-Frequency and Flanking Bands?
Fig. 52.1 Examples of the waveforms (top row) and schematic plots of the spectrograms (bottom row) of the stimuli for the conditions RF (left column), CM (middle column) and CD…
Stimulus-Specific Adaptation Beyond Pure Tones
Fig. 45.1 The two noise tokens used in the SSA experiments. (a) Waveforms of the first 30 ms of each of the two tokens. (b) Power spectra of the two…
Temporal Coherence and the Streaming of Complex Sounds
Fig. 59.1 Temporal coherence model. The mixture (sum of one male and one female sentences) is transformed into an auditory spectrogram. Various features are extracted from the spectrogram including a…
Pitch Perception: Dissociating Frequency from Fundamental-Frequency Discrimination
Fig. 16.1 Percentage of correct responses in the melody-discrimination task. Error bars show 95 % confidence intervals 2.3 Discussion The results suggest that tones above 6 kHz can elicit a…
Mapping Tonotopy in Human Auditory Cortex
Fig. 46.1 Two principal components were extracted, each consisting of a single frequency profile (left) and corresponding spatial maps for both subject groups (right). The first component (PC1, top) summarized…
