Thanks to the development of deep learning, various sound source separation networks have been proposed and made significant progress. However, the study on the underlying separation mechanisms is still in its infancy. In this study, deep networks are explained from the perspective of auditory perception mechanisms. For separating two arbitrary sound sources from monaural recordings, three different networks with different parameters are trained and achieve excellent performances. The networks’ output can obtain an average scale-invariant signal-to-distortion ratio improvement (SI-SDRi) higher than 10 dB, comparable with the human performance to separate natural sources. More importantly, the most intuitive principle—proximity—is explored through simultaneous and sequential organization experiments. Results show that regardless of network structures and parameters, the proximity principle is learned spontaneously by all networks. If components are proximate in frequency or time, they are not easily separated by networks. Moreover, the frequency resolution at low frequencies is better than at high frequencies. These behavior characteristics of all three networks are highly consistent with those of the human auditory system, which implies that the learned proximity principle is not accidental, but the optimal strategy selected by networks and humans when facing the same task. The emergence of the auditory-like separation mechanisms provides the possibility to develop a universal system that can be adapted to all sources and scenes.

In multi-talker listening environments, the culmination of different voice streams may lead to the distortion of each source’s individual message, causing deficits in comprehension. Voice characteristics, such as pitch and timbre, are major dimensions of auditory perception and play a vital role in grouping and segregating incoming sounds based on their acoustic properties. The current study investigated how pitch and timbre cues (determined by fundamental frequency, notated as F0, and spectral slope, respectively) can affect perceptual integration and segregation of complex-tone sequences within an auditory streaming paradigm. Twenty normal-hearing listeners participated in a traditional auditory streaming experiment using two alternating sequences of harmonic tone complexes A and B with manipulating F0 and spectral slope. Grouping ranges, the F0/spectral slope ranges over which auditory grouping occurs, were measured with various F0/spectral slope differences between tones A and B. Results demonstrated that the grouping ranges were maximized in the absence of the F0/spectral slope differences between tones A and B and decreased by 2 times as their differences increased to ±1-semitone F0 and ±1-dB/octave spectral slope. In other words, increased differences in either F0 or spectral slope allowed listeners to more easily distinguish between harmonic stimuli, and thus group them together less. These findings suggest that pitch/timbre difference cues play an important role in how we perceive harmonic sounds in an auditory stream, representing our ability to group or segregate human voices in a multi-talker listening environment.

The objective of this work is to confirm the asymmetry in non-linguistic auditory perception, as well as the influence of anxiety-depressive disorders on it. Eighty-six people were recruited in the emotional well-being group, fifty-six in the anxiety group, fourteen in the depression group, and seventy-seven in the mixed group. In each group, audiograms were obtained from both ears and the differences were statistically analyzed. Differences in hearing sensitivity were found between both ears in the general population, such differences increased in people with anxiety-depressive disorders. When faced with anxiety-depressive disorders, the right ear suffered greater hearing loss than the left, showing peaks of hyper-hearing at the frequency of 4000 Hz in the anxiety subgroup, and hearing loss in the depression subgroup. In relation to anxiety, the appearance of the 4:8 pattern was observed in the right ear when the person had suffered acute stress in the 2 days prior to the audiometry, and in both ears if they had suffered stress in the 3–30 days before said stress. In conclusion, the advantage of the left ear in auditory perception was increased with these disorders, showing a hyperaudition peak in anxiety and a hearing loss in depression.

Environmental Acoustics is a professional course that educates students majoring in Acoustics. Affected by practical equipment and other factors, the teaching effect of knowledge points relevant to subjective auditory perception contained in the course is poor. Taking the course of Spatial Hearing and 3D Stereo as an example, this study develops a virtual simulation experiment system for the topic of subjective hearing perception in order to carry out the reform and practice of immersive teaching. Combined with the virtual simulation experiment project with high sense of presence, students are supported by the actual auditory perception effect in the whole learning process and have achieved good learning effect.

The aim of this article is an attempt to give an answer the question: What is the level of listening skills of the students who come to post-primary school? The author presents the results of research that she carried out using authorial listening comprehension texts. The research involved a group of 162 eighth grade students from four primary schools in Opole. The data obtained from this research show that eighth-graders demonstrate an average level of listening skills, there fore schools should take preventive measures aimed at in creasing the effectiveness of auditory perception.

AbstractThe varied effects of expectations on auditory perception are not well understood. For example, both top-down rules and bottom-up stimulus regularities generate expectations that can bias subsequent perceptual judgments. However, it is unknown whether these different sources of bias use the same or different computational and physiological mechanisms. We examined how rule-based and stimulus-based expectations influenced human subjects’ behavior and pupil-linked arousal, a marker of certain forms of expectation-based processing, during an auditory frequency-discrimination task. Rule-based cues biased choice and response times (RTs) toward the more-probable stimulus. In contrast, stimulus-based cues had a complex combination of effects, including choice and RT biases toward and away from the frequency of recently heard stimuli. These different behavioral patterns also had distinct computational signatures, including different modulations of key components of a novel form of a drift-diffusion model, and distinct physiological signatures, including substantial bias-dependent modulations of pupil size in response to rule-based but not stimulus-based cues. These results imply that different sources of expectations can modulate auditory perception via distinct mechanisms: one that uses arousal-linked, rule-based information and another that uses arousal-independent, stimulus-based information to bias the speed and accuracy of auditory perceptual decisions.

Combining sketch studies, musical analysis, and acoustic analysis, this article examines the impact of spectral models on Grisey’s creative process in the 1970s. First, it focuses on Grisey’s establishment of initial theoretical models in Dérives and Périodes, composed during his residence at the Villa Medici (1972–74), during which period he conducted his own study of acoustics. The article then looks at how, back in Paris, the composer started studying with the acoustician Émile Leipp and then worked with Michèle Castellengo, with whom in 1977 he undertook for the first time the spectral analysis of instrumental sounds. Finally the article examines in detail how some spectrograms, once transcribed, were used in Modulations (1976–77) to construct a complex spectral polyphony. If Grisey draws his inspiration from sound phenomena and the characteristics of auditory perception, he does not for all that neglect structuralism: spectral models serve both to simulate natural phenomena and to formalise his compositional processes.

Cognitive readiness is a level of cognitive skills sufficient for systematic learning. It includes cognitive processes (perception, memory, thinking, imagination, and speech), knowledge, skills, motivation, etc. The research featured cognitive readiness for primary school in senior preschoolers after a special correction and development program "School is Waiting", which was based on a series of games. The program proved to be highly effective as tested by L. S. Kolmogorova’s diagnostic program "Readiness for School". Children in the test group received a higher total score for knowledge, long-term memory, auditory perception, speech, imagination, etc. than those in the control group.
