Opis:: The physical phenomena occurring in sound-absorbing and insulating enclosures are subject of the present paper. These phenomena are: absorption in air and by the sound-absorbing material covering the walls and the coincidence effect. The absorption in the air can be neglected in small size enclosures for low ultrasonic frequencies (20–30 kHz). The coincidence plays a role in decrease of the sound insulation, however the main role play the leaks. The boards made of ceramic fibers have been chosen as the optimal sound-absorbing material. They are dense and have deeply porous structures. The enclosure for insulation of 20-kHz noise produced by a welding machine has been designed and manufactured, and reductions of 25 dB of peak and Leq levels have been achieved.

Opis:: Safety and security have been a prime priority in people’s lives, and having a surveillance system at home keeps people and their property more secured. In this paper, an audio surveillance system has been proposed that does both the detection and localization of the audio or sound events. The combined task of detecting and localizing the audio events is known as Sound Event Localization and Detection (SELD). The SELD in this work is executed through Convolutional Recurrent Neural Network (CRNN) architecture. CRNN is a stacked layer of convolutional neural network (CNN), recurrent neural network (RNN) and fully connected neural network (FNN). The CRNN takes multichannel audio as input, extracts features and does the detection and localization of the input audio events in parallel. The SELD results obtained by CRNN with the gated recurrent unit (GRU) and with long short-term memory (LSTM) unit are compared and discussed in this paper. The SELD results of CRNN with LSTM unit gives 75% F1 score and 82.8% frame recall for one overlapping sound. Therefore, the proposed audio surveillance system that uses LSTM unit produces better detection and overall performance for one overlapping sound.

Tytuł:: The psycholinguistic world of “zdziwienie” - “astonishment” and “zaskoczenie” - “surprise”
Autorzy:: Jasielska, Aleksandra

Wydawca:: Polska Akademia Nauk. Czytelnia Czasopism PAN
Tematy:: surprise
astonishment
psycholinguistics
denotative and connotative meaning
emotional valence
conventional sound symbolism
Opis:: The aim of the study was to answer the question whether the words “zaskoczenie” [phon. zaskɔˈʧ̑ɛ̃ɲɛ]- “surprise” and “zdziwienie” [phon. ʑʥ̑iˈvjɛ̇̃ɲɛ]- “astonishment”, which are treated in the Polish language as synonyms, possess a fixed pattern of application, and whether the colloquial context of using these words differs in terms of its emotional valence. The theoretical background for this investigation was the triadic approach to language cognition that includes perception, conceptualization and symbolization, and corresponding to this approach concept of mental representation of emotions. The obtained results have shown that people tend to use the word “zaskoczenie” to describe emotions that occur in positive situations, whereas the word “zdziwienie” is more frequently applied in negative situations. The observed emotive connotation of the investigated words has been explained by the rules of phonetic symbolism and implicative meaning of the words preserved in the popular/colloquial understanding.
