    Opis:
    This study aims to illustrate how visual and auditory perception are conceptualized in Swedish and what differences there are between them. Previous studies often discuss perception in relation to the oppositely directed motions between the perceiver and the object perceived. In the Perceiver-as-Source type, perception occurs when our eyes/gaze reach the object perceived. In the Perceived-as-Source type, perception takes place when sense stimuli reach the perceiver. The data show two differences between visual and auditory perception. First, we find more metaphorical expressions for visual perception than for auditory perception. Second, we also find that, while visual perception has a stronger connection to the Perceiver-as-Source type, auditory perception is more strongly connected to the Perceived-as-Source type. These two differences are explained by the function of the perceptual organs.

    Opis:
    Background: It has been evidenced that the outcome of a CVA patient differs as a function of the cerebral hemisphere that is damaged by the stroke, especially in terms of emotional changes. In contrast, the Bi-Hemispheric Model of Emotion posits that each hemisphere has its own emotional specialization. The current experiment tested the competing predictions of the two theoretical perspectives in a mixed sample of left cerebrovascular accident (LCVA) patients and right cerebrovascular accident (RCVA) patients using a Dichotic Listening task and the Affective Auditory Verbal Learning Test (AAVLT). Heart Rate (HR) and Pulse Oxygen Saturation (SpO2) were recorded as sympathetic measures. It was expected that the predictions of the Bi-Hemispheric Model would be supported. A series of mixed design ANOVAs were used to analyze the data. Material/Methods: Participants consisted of 21 patients grouped into either post-acute status left cerebrovascular accident (LCVA) or right cerebrovascular accident (RCVA). Tests included the The Dichotic Listening test, The Affective Auditory Verbal Learning Test (AAVLT), HR and Sp02 measurement using a Fingertip Pulse Oximeter and the Mood Assessment Scale for depression. Results: Results revealed that both groups exhibited decreased auditory detection abilities in the ear contralateral to CVA location. Additionally, CVA patients recalled significantly more positive words than negative or neutral words and exhibited a significant learning curve. LCVA patients exhibited a recency effect, while RCVA patients exhibited a heigh tened primacy effect. Findings from the HR and Sp02 measures suggested a parasympathetic response to emotionally neutral information as well as an impaired sympathetic response to emotionally negative information in RCVA patients. Conclusions: The results lend partial support to the hypothesis drawn from the Bi-Hemispheric Model of Emotion, as evidenced by the diametrically opposite effects in these groups, which reflects opposing cerebral processes.

    Opis:
    The present study consisted of two experiments. The goal of the first experiment was to establish the just noticeable differences for the fundamental frequency of the vowel /u/ by using the 2AFC method. We obtained the threshold value for 27 cents. This value is larger than the motor reaction values which had been observed in previous experiments (e.g. 9 or 19 cents). The second experiment was intended to provide neurophysiological confirmation of the detection of shifts in a frequency, using event-related potentials (ERPs). We concentrated on the mismatch negativity (MMN) - the component elicited by the change in the pattern of stimuli. Its occurrence is correlated with the discrimination threshold. In our study, MMN was observed for changes greater than 27 cents - shifts of ±50 and 100 cents (effect size - Cohen’s d = 2.259). MMN did not appear for changes of ±10 and 20 cents. The results showed that the values for which motor responses can be observed are indeed lower than those for perceptual thresholds.

    Opis:
    This paper proposes a speech enhancement method using the multi-scales and multi-thresholds of the auditory perception wavelet transform, which is suitable for a low SNR (signal to noise ratio) environment. This method achieves the goal of noise reduction according to the threshold processing of the human ear’s auditory masking effect on the auditory perception wavelet transform parameters of a speech signal. At the same time, in order to prevent high frequency loss during the process of noise suppression, we first make a voicing decision based on the speech signals. Afterwards, we process the unvoiced sound segment and the voiced sound segment according to the different thresholds and different judgments. Lastly, we perform objective and subjective tests on the enhanced speech. The results show that, compared to other spectral subtractions, our method keeps the components of unvoiced sound intact, while it suppresses the residual noise and the background noise. Thus, the enhanced speech has better clarity and intelligibility.

    Opis:
    Bierwiaczonek (2013: 201-202) proposed an analysis of the polysemy of the verb see based on propositional metonymic mappings. In Matusz (2020) I supported this claim with a short dictionary analysis. In the present paper, I propose a similar analysis of the polysemy of hear based on propositional metonymy processes. In order to do that a short dictionary analysis is performed to determine the basic non-metonymic meaning of the verb and to distinguish the senses motivated by metonymic mappings. The analysis performed on the basis of three dictionary sources shows that a significant number of senses of hear may plausibly be explained as cases of PART FOR WHOLE propositional metonymic patterns. The metonymic shift may be demonstrated on the basis of State-of-Affairs Scenarios (SASs), as proposed by Panther and Thornburg (1999), due to the fact that within such scenarios the stage of auditory perception constitutes a particularly salient stage (a stage of SAS for SAS). Alternatively, some dictionary samples are ambiguous between the PART FOR WHOLE metonymic interpretation and the metaphoric reading wherein metonymy plays an active role in the emergence of the metaphoric shift. Thus, reference to metonymy-metaphor interaction appears indispensable. In the paper, I propose an analysis of such cases based on Ruiz de Mendoza and Díez Velasco (2002), who consider the role of metonymic domain expansion within the source of the metaphoric mappings.

    Opis:
    Principal components analysis (PCA) is frequently used for modelling the magnitude of the head- related transfer functions (HRTFs). Assuming that the HRTFs are minimum phase systems, the phase is obtained from the Hilbert transform of the log-magnitude. In recent years, the PCA applied to HRTFs is also used to model individual HRTFs relating the PCA weights with anthropometric measurements of the head, torso and pinnae. The HRTF log-magnitude is the most used format of input data to the PCA, but it has been shown that if the input data is HRTF linear magnitude, the cumulative variance converges faster, and the mean square error (MSE) is smaller. This study demonstrates that PCA applied directly on HRTF complex values is even better than the two formats mentioned above, that is, the MSE is the smallest and the cumulative variance converges faster after the 8th principal component. Different objective experiments around all the median plane put in evidence the differences which, although small, seem to be perceptually detectable. To elucidate this point, psychoacoustic discrimination tests are done between measured and reconstructed HRTFs from the three types of input data mentioned, in the median plane between −45◦ and +90◦.

    Opis:
    This text analyses several topics connected with hearing test methods and hearing prosthetics for patients with hearing impairments or hearing loss. The hearing is one of the senses which plays a crucial part in human's cognition of the surrounding world and spatial orientation. Proper functioning of the hearing organ is a foundation of communication between people as well as the development of civil society. A hearing impairment or hearing loss disrupts social relationships between people, it entails developmental disorders in children, and causes learning difficulties. Methods of diagnosing patients and hearing prosthetics are very complex topics and are investigated by interdisciplinary research teams. The development of these fields of medicine and technology contributes to improving the quality of life for people with hearing impairment or deafness. This paper presents ways and means of improving or compensating for hearing losses with the use of hearing aids. Nowadays, hearing impairments and hearing losses concern even young people. One of the reasons for the deterioration of hearing is the ubiquitous noise in the modern world. Moreover, this text discusses the construction of hearing aids, with a particular emphasis placed on modern technological solutions. It is highlighted that hearing aids are currently available for the general public.
    W pracy dokonano analizy zagadnień związanych z metodami badania i protetyki słuchu pacjentów z niedosłuchem i ubytkiem słuchu. Słuch jest jednym z receptorów, który odgrywa u człowieka ważną rolę w poznawaniu otaczającego świata i orientacji w przestrzeni. Prawidłowe funkcjonowanie narządu słuchu stanowi podstawę komunikacji między ludźmi i rozwoju społeczeństwa. Uszkodzenie lub utrata słuchu zaburza relacje społeczne między ludźmi, powoduje zaburzenia rozwoju u dzieci oraz trudności w nauce. Metody diagnozowania pacjentów i protetyka słuchu stanowią bardzo złożone zagadnienia, którymi zajmują się interdyscyplinarne zespoły badawcze. Rozwój tych dziedzin medycyny i techniki przyczynia się do poprawy jakości życia osób z niedosłuchem lub głuchotą. Przedstawiono w pracy sposoby i możliwości poprawy lub kompensacji ubytków słuchu za pomocą aparatów słuchowych. Wady i ubytki słuchu dotyczą obecnie nawet młodych ludzi. Jedną z przyczyn pogorszenia się słuchu u człowieka jest otaczający nas we współczesnym świecie hałas. Zaprezentowano też w pracy budowę aparatu słuchowego, ze szczególnym uwzględnieniem nowoczesnych rozwiązań technologicznych. Podkreślono, że aparaty słuchowe są obecnie dostępne dla ogółu społeczeństwa.

    Opis:
    Sound and vibrations are often perceived via the auditory and tactile senses simultaneously, e.g., in a car or train. During a rock concert, the body vibrates with the rhythm of the music. Even in a concert hall or a church, sound can excite vibrations in the ground or seats. These vibrations might not be perceived separately because they integrate with the other sensory modalities into one multi-modal perception. This paper discusses the relation between sound and vibration for frequencies up to 1 kHz in an opera house and a church. Therefore, the transfer function between sound pressure and acceleration was measured at different exemplary listening positions. A dodecahedron loudspeaker on the stage was used as a sound source. Accelerometers on the ground, seat and arm rest measured the resulting vibrations. It was found that vibrations were excited over a broad frequency range via airborne sound. The transfer function was measured using various sound pressure levels. Thereby, no dependence on level was found. The acceleration level at the seat corresponds approximately to the sound pressure level and is independent of the receiver position. Stronger differences were measured for vibrations on the ground.

    Opis:
    The head-related transfer function (HRTF) is dependent on the position of the sound source (both direction and distance) and is also affected by individual anatomical parameters. Individualized HRTFs have been shown to affect the perception of sound direction, but have not been considered in distance perception. This work aims to discover, by means of psychoacoustic experiments for a virtual reproduction system through a pair of in-ear headphones, the effect of individualized HRTF on auditory distance perception for a nearby sound source. The individualized HRTFs of six subjects and the non-individualized HRTFs of a mannequin at seven distances between 0.2 and 1.0 m and five lateral azimuths between 45° and 135° in the horizontal plane were processed with white noise to generate binaural signals. Further, the individualized and non-individualized HRTFs were used in the auditory distance perception experiments. Results of distance perception show that the variance of distance perception results among subjects is significant, the reason could be the stimuli are lack of dynamic cue and early reflections, or the audi tory difference of distance perception among subjects. However, via the analyses of mean slope of perceptual distance and correlation between the perceptual and real distance, we find that the individualized HRTF cue has insignificant influence on distance perception.

To this end, while analyzing the text, I refer to concepts regarding the nature of melancholia and adopt the methodological apparatus of sound studies. As it turns out, the listener's attitude is crucial for overcoming melancholia. According to the poet, attentive listening to the surroundings and the words of other people allows to reach the meaning of life inscribed in nature and as a consequence may help find a cure for melancholia.

    Opis:
    This work addresses the problem of difficulties in classical interpretation of combination tones as non- linear distortions. One of the basic problems of such an interpretation is to point out the sources of these distortions. Besides, these kinds of distortions have numerous “anomalies” which are difficult to explain on the grounds of physics or physiology. The aim of the model presented in this paper is to show that combination tones phenomenon can be explained as an effect of central mechanisms. Most of existing theories of pitch perception focus mainly on virtual pitch perception and do not take into account com- bination tones as an element of the same mechanism. The proposed model of central auditory processing for pitch perception allows one to interpret in a coherent way both virtual pitches and combination tones phenomena. This model is of a demonstrative nature and gives an introduction to more advanced model. It belongs to the class of spectral models and it will be shown that such a model can be in a simple way extended to spectral – time model which is partially consistent with autocorrelation models.

    Opis:
    In this study, we aimed to determine the role of visual speech cues in the process of foreign language learning by hearing school-age children. Our experiments used Cued Speech, a method designed for people who are deaf or hard of hearing. We expected that the principles of the method might also be beneficial for people with normal hearing because they may help distinguish the sounds of foreign speech that are difficult to hear. This study mainly focused on the effects of speech perception. We tested 126 Polish junior high school students (66 girls and 60 boys) with a normal range of phonemic hearing and language aptitude. We envisaged that foreign language learners using visual speech cues would achieve a higher score on a test of foreign language than learners who had studied the language in the traditional manner. We also formulated a hypothesis concerning the interaction of training type and training conditions on the effectiveness of foreign language learning: that the difference in the effects of foreign language learning between participants who received visual or executive training and typical training would be more significant in the presence of auditory distractors than in their absence. We observed interactions between conditions and types of training for speech sound identification. Under conditions of auditory distraction, foreign language learners using Cued Speech scored significantly higher than learners who had traditional training.

    Opis:
    Space is usually perceived and examined as a tridimensional, but visual construct. The article shows it as a process, in which both external (systemic, environmental) and internal (psychological, physical) factors matter. They are important in all kinds of space perception, including the auditory one, which is often disregarded. Meanwhile, it can furnish rich information on one’s point in the space, events happening around, character and function of a place etc. What cannot be ignored is that “auditory spatial awareness” [Blesser, 2007] influences people’s behavior. This is the reason why architects, governments and artists start to pay attention to this phenomenon, while social researchers do surveys. Their cooperation can be seen in Evidence-Based Design architectonic trend or Project for Public Spaces. Similar, but stricter requirements are set by the European Commission. But surrounding sounds are not only damaging and disturbing. Many of them are helpful, provide information, give solace and many are parts of soundmarks, “acoustic landmarks”; are components of identity. Gathering sounds, often ascribed to places, became a new kind of entertainment and artistic activity.

    Opis:
    This article presents the prevalence of auditory verbal hallucinations (AVHs) across the life span in various clinical and nonclinical groups in childhood, adolescence, and adult populations. Data on the occurrence of this phenomenon in the general population vary and usually are in the range of 5–28%. The prevalence of non-clinical AVHs is similar in childhood, adolescence and adulthood. It seems possible that the mechanisms which cause AVHs in non-clinical populations are different from those which are behind AVHs presentations in psychotic illness. In this paper the characteristics of differentiating clinical forms of hallucinations from the non-clinical ones are discussed. These are: the location of sensations, their content, inhibition control disorders, metacognitive disorders, emotional dysregulation, stress level, and their influence on functioning disorders. Considered as etiological factors are abnormal activities of some areas of the brain and abnormal pruning. The triggering factors of both types of perception disorders are traumatic events and psychoactive substances use. Long-term studies have shown that the factors which lead to the transformation of non-clinical hallucinations into their clinical forms are: genetic predisposition, schizotypy, at-risk mental state, and stress. The future research needs to focus on the comparison of underlying factors and mechanisms that lead to the onset of AVHs in both patients and non-clinical populations.
    W artykule przedstawiono częstość występowania słuchowych słownych halucynacji (SSH) w ciągu życia w różnych klinicznych i nieklinicznych grupach, w populacjach dzieci, młodzieży oraz osób dorosłych. Dane dotyczące występowania tego zjawiska w populacji ogólnej różnią się i z reguły mieszczą się w przedziale od 5% do 28%. Rozpowszechnienie nieklinicznych postaci SSH jest podobne w okresie dzieciństwa, adolescencji i dorosłości. Wydaje się możliwe, że mechanizmy powodujące powstanie nieklinicznych SSH są różne od tych, które prowadzą do rozwoju postaci klinicznych. Omówiono cechy różnicujące postaci kliniczne halucynacji tego typu od ich form nieklinicznych. Należą do nich: lokalizacja doznań, ich treść, zaburzenia kontroli hamowania, zaburzenia metapoznawcze, dysregulacja emocjonalna, poziom przeżywanego stresu z powodu doznań oraz ich wpływ na zaburzenia codziennego funkcjonowania. Za czynniki etiologiczne uznaje się zaburzenia aktywności określonych obszarów mózgu oraz zaburzony proces czyszczenia synaps. Do czynników spustowych wystąpienia obu postaci zaburzeń spostrzegania zalicza się wydarzenia traumatyczne i używanie substancji psychoaktywnych. Z długoterminowych badań wynika, że czynnikami sprzyjającymi przemianie nieklinicznych SSH w postać kliniczną są przede wszystkim: predyspozycja genetyczna, schizotypia, ryzykowny stan psychiczny oraz wydarzenia stresujące. Przyszłe badania muszą skupić się na porównaniu podstawowych czynników i mechanizmów, które prowadzą do wystąpienia SSH, zarówno w populacjach pacjentów, jak i w populacjach nieklinicznych.
