Immersive Audio

Abstract Although virtual reality, video entertainment, and computer games are dependent on the three-dimensional reproduction of sound (including front, rear, and height channels), it remains unclear whether 3D-audio formats actually intensify the emotional listening experience. There is currently no valid inventory for the objective measurement of immersive listening experiences resulting from audio playback formats with decreasing degrees of immersion (from mono to stereo, 5.1, and 3D). The development of the Immersive Audio Quality Inventory (IAQI) could close this gap. An initial item list (N = 25) was derived from studies in virtual reality and spatial audio, supplemented by researcher-developed items and items extracted from historical descriptions. Psychometric evaluation was conducted by an online study (N = 222 valid cases). Based on controlled headphone playback, participants listened to four songs/pieces, each in the three formats of mono, stereo, and binaural 3D audio. The latent construct “immersive listening experience” was determined by probabilistic test theory (item response theory, IRT) and by means of the many-facet Rasch measurement (MFRM). As a result, the specified MFRM model showed good model fit (62.69% of explained variance). The final one-dimensional inventory consists of 10 items and will be made available in English and German.

Back Massage

Disease that is often complained by the public today one of the pain in the bone, which is better known by the community with rheumatism. Rheumatism or rheumatoid arthritis is a systemic, progressive, chronic and tendonic inflammatory disease of joints and connective tissue symmetrically. One way of management of rheumatoid arthritis pain is back massage therapy. Back Massage is one of the techniques to give massage action on the back with lotions/balm for 10-15 minutes, the warm sensation leads to vasodilation of blood vessels that will improve blood circulation in the area so that the activity of the cell is increased and will reduce pain, increase comfort, reduce muscle tension and improve physical and psychological relaxation. This study aims to determine the effect of Back massage therapy to decrease the pain level of rheumatoid arthritis patients in Rajadesa Village Rajadesa Sub District Ciamis District in 2018. Type of research using Quasi Experiment Design with one group pretest-posttest design. Total sample 48 respondents with total sampling technique. Data collection using experimental method with VDS (Verbal Descriptor Scale) pain rate measurement tool. The result of statistical test by using Linear Regression shows Sig = 0,000 <0,05, t value = 18,935> 2,012. Then Ha is accepted, and the average value before therapy is 3.27 with a standard deviation of 0.818, whereas after therapy is 2.23 with a standard deviation of 0.881, meaning there is the effect of back massage therapy on the decrease of pain level in patients with rheumatoid arthritis. So to reduce pain in patients with rheumatoid arthritis can be given back massage therapy.

Abstract This article presents a novel tool designed to allow circuit node measurements in a radio frequency (RF) integrated circuit. The discussion covers RF circuit problems; provides details on the Radio Probe design, which achieves an input impedance of 50Kohms and an overall attenuation factor of 0 dB; and describes signal to noise issues in the output signal, along with their improvement techniques. This cost-effective solution incorporates features that make it well suited to the task of differential measurement of circuit nodes within an RF IC. The Radio Probe concept offers a number of advantages compared to active probes. It is a single frequency measurement tool, so it complements, rather than replaces, active probes.
