In the Southern Bavarian variety of Tyrolean, laryngeal contrasts undergo a typologically interesting process of neutralisation in word-initial position. We undertake an acoustic analysis of Tyrolean stops in word-initial, word-medial intersonorant and word-final contexts, as well as in obstruent clusters, investigating the role of the acoustic parameters VOT, prevoicing, closure duration and F0 and H1–H2* on following vowels in implementing contrast, if any. Results show that stops contrast word-medially via [voice] (supported by the acoustic cues of closure duration and F0), and are neutralised completely in word-final position and in obstruent clusters. Word-initially, neutralisation is subject to inter- and intraspeaker variability, and is sensitive to place of articulation. Aspiration plays no role in implementing laryngeal contrasts in Tyrolean.

Musical Listening

Musical listening is broadly used as an inexpensive and safe method to reduce self-perceived anxiety. This strategy is based on the emotivist assumption claiming that emotions are not only recognised in music but induced by it. Yet, the acoustic properties of musical work capable of reducing anxiety are still under-researched. To fill this gap, we explore whether the acoustic parameters relevant in music emotion recognition are also suitable to identify music with relaxing properties. As an anxiety indicator, the positive statements from the six-item Spielberger State-Trait Anxiety Inventory, a self-reported score from 3 to 12, are taken. A user-study with 50 participants assessing the relaxing potential of four musical pieces was conducted; subsequently, the acoustic parameters were evaluated. Our study shows that when using classical Western music to reduce self-perceived anxiety, tonal music should be considered. In addition, it also indicates that harmonicity is a suitable indicator of relaxing music, while the role of scoring and dynamics in reducing non-pathological listener distress should be further investigated.

Acoustical Properties

AbstractThe overall experience of religious practice is significantly affected by the acoustical properties of temples. Divine service is the most important act in the Orthodox Church, which equally demands intelligibility of speech for preaching and as well as adequate acoustics for Byzantine chanting as a form of a song-prayer. In order to better understand and contribute to unlocking the role of sound in these historical sacral spaces, this paper explores the acoustics of two well-preserved Orthodox churches, from Ljubostinja and Naupara monastery, built in the last building period of medieval Serbia (1371–1459). These represent two types of the Morava architectural style – triconch combined with a developed and compressed inscribed cross, respectively. Using EASERA software, we measured the impulse response for two sound source positions – in the altar and in the southern chanting apse, as the main points from which the Orthodox service is carried out. Thus obtained acoustic parameters (RT, EDT, C50 and STI) were further analysed, pointing out the differences in experiencing sound between naos and narthex, as well as how the position of the sound source influenced the experience of sound. Finally, we compared the results with previous archaeoacoustic research of the churches from the same building period.

Abstract We have seen a rapid growth of interest in cross-modal correspondences between sound and taste over recent years. People consistently associate higher-pitched sounds with sweet/sour foods, while lower-pitched sounds tend to be associated with bitter foods. The human voice is key in broadcast advertising, and the role of voice in communication generally is partly characterized by acoustic parameters of pitch. However, it remains unknown whether voice pitch and taste interactively influence consumer behavior. Since consumers prefer congruent sensory information, it is plausible that voice pitch and taste interactively influence consumers’ responses to advertising stimuli. Based on the cross-modal correspondence phenomenon, this study aimed to elucidate the role played by voice pitch–taste correspondences in advertising effectiveness. Participants listened to voiceover advertisements (at a higher or lower pitch than the original narrator’s voice) for three food products with distinct tastes (sweet, sour, and bitter) and rated their buying intention (an indicator of advertising effectiveness). The results show that the participants were likely to exhibit greater buying intention toward both sweet and sour food when they listened to higher-pitched (vs lower-pitched) voiceover advertisements. The influence of a higher pitch on sweet and sour food preferences was observed in only two of the three studies: studies 1 and 2 for sour food, and studies 2 and 3 for sweet food. These findings emphasize the role that voice pitch–taste correspondence plays in preference formation, and advance the applicability of cross-modal correspondences to business.
