Abstract
Being able to produce sounds that capture attention and elicit rapid reactions is the prime goal of communication. One strategy, exploited by alarm signals, consists in emitting fast but perceptible amplitude modulations in the roughness range (30–150 Hz). Here, we investigate the perceptual and neural mechanisms underlying aversion to such temporally salient sounds. By measuring subjective aversion to repetitive acoustic transients, we identify a nonlinear pattern of aversion restricted to the roughness range. Using human intracranial recordings, we show that rough sounds do not merely affect local auditory processes but instead synchronise large-scale, supramodal, salience-related networks in a steady-state, sustained manner. Rough sounds synchronise activity throughout superior temporal regions, subcortical and cortical limbic areas, and the frontal cortex, a network classically involved in aversion processing. This pattern correlates with subjective aversion in all these regions, consistent with the hypothesis that roughness enhances auditory aversion through spreading of neural synchronisation. Results: The music therapy group showed statistically significant decrease in anxiety compared to control group but no significant difference was identified in stress and maternal-fetal attachment. Conclusions The finding provides evidence for use of nursing intervention in prenatal care unit to reduce pregnant women’s anxiety. Further research is necessary to test the benefits of music therapy with different frequency and duration. [Asian Nursing Research 2011;5(1):19–27]

Abstract
The complexity of EEG signals make it difficult to analyze and understand hence a common method is to create a mathematical model from which approximate measurable quantities can be derived. Statistical approaches are commonly used to describe stochastic systems that produce random data sets. This study aims to characterize EEG signals due to musical tone stimulation. The characterization is based on the statistical measures of the power spectrum in the beta and alpha frequency range. Measures of central tendencies were considered as well as the alpha asymmetric properties of the left and right hemispheres of the brain during stimulation. The EEG signals were obtained using a 14-node neuro-headset from Emotiv. For an initial study, seventeen volunteers joined the experiment producing 17, 102, 51 and 204 data samples for the Baseline, C, F and G, and s-Baseline segments, respectively. Data pre-processing, filtering and power spectrum feature extraction were performed to gather enough information for analysis. Results show that among the considered statistical measures, the skewness and kurtosis of the power spectrum were found to be significant in delineating the different segments of the audio stimuli. The inverse relationship between the beta and alpha waves was observed. During active segments of the audio stimulus, alpha power decreases and beta power increases and vice versa. Using the difference score method (DSM) and with the assumption that alpha waves are inversely proportional to activity, high DSM values were observed during the active segments of the stimuli thus implying higher left hemisphere activation. On the contrary, low DSM values were observed during the inactive segments of the stimuli thus implying a higher right hemisphere activation. A decreasing DSM trend was observed from the intermediate node between the frontal polar site and frontal node to the parietal node. This is indicative of more frontal activation towards a less activation on the parietal region.

Abstract
The study aimed at examining whether methodological strategies from a previously implemented study design could be transferred to the evaluation of the psychological and physiological effects of a music therapy intervention working with vibroacoustic stimulation in palliative care.

Abstract
Purpose: The purpose of this study was to examine the effects of music therapy on anxiety, stress and maternal-fetal attachment in pregnant women during a transvaginal ultrasound.
Methods: This study was a nonequivalent control group nonsynchronized design. Pregnant women (n = 232) were assigned to experimental (n = 117) and control (n = 116) groups respectively. The data were collected from August 2 to 27, 2010. The experimental group received general prenatal care and single 30- minute session of music therapy, while the control group received only general prenatal care. Anxiety, stress, and maternal-fetal attachment was assessed using three self-report measures by State scale of the State-Trait Anxiety Inventory (1976), Pregnant women’s stress scale of Ahn (1984) and Cranley’s (1981) maternal-fetal attachment scale.
Results: The music therapy group showed statistically significant decrease in anxiety compared to control group but no significant difference was identified in stress and maternal-fetal attachment. Conclusions The finding provides evidence for use of nursing intervention in prenatal care unit to reduce pregnant women’s anxiety. Further research is necessary to test the benefits of music therapy with different frequency and duration. [Asian Nursing Research 2011;5(1):19–27]

Abstract
Our study focuses on mood induction with pleasant and un- pleasant auditory stimuli during the break. Our test includes sub- jective evaluation (NASA-TLX, KSS, POMS), cognitive tests and brain responses (MEG and EEG). We aim studying the effect affective state has on work-like tasks. Hypothesis: pleasantness of auditory mood induction affects cognitive performance and brain responses.
