Music Appraisal

AbstractAlthough for most cochlear implant (CI) users good speech understanding is reached (at least in quiet environments), the perception and the appraisal of music are generally unsatisfactory.The improvement in music appraisal was evaluated in CI participants by using a stereo music preprocessing scheme implemented on a take-home device, in a comfortable listening environment. The preprocessing allowed adjusting the balance among vocals/bass/drums and other instruments, and was evaluated for different genres of music. The correlation between the preferred settings and the participants’ speech and pitch detection performance was investigated.During the initial visit preceding the take-home test, the participants’ speech-in-noise perception and pitch detection performance were measured, and a questionnaire about their music involvement was completed. The take-home device was provided, including the stereo music preprocessing scheme and seven playlists with six songs each. The participants were asked to adjust the balance by means of a turning wheel to make the music sound most enjoyable, and to repeat this three times for all songs.Twelve postlingually deafened CI users participated in the study.The data were collected by means of a take-home device, which preserved all the preferred settings for the different songs. Statistical analysis was done with a Friedman test (with post hoc Wilcoxon signed-rank test) to check the effect of “Genre.” The correlations were investigated with Pearson’s and Spearman’s correlation coefficients.All participants preferred a balance significantly different from the original balance. Differences across participants were observed which could not be explained by perceptual abilities. An effect of “Genre” was found, showing significantly smaller preferred deviation from the original balance for Golden Oldies compared to the other genres.The stereo music preprocessing scheme showed an improvement in music appraisal with complex music and hence might be a good tool for music listening, training, or rehabilitation for CI users.

Music Appraisal

The research examined whether performance by adult cochlear implant recipients on a variety of recognition and appraisal tests derived from real-world music could be predicted from technological, demographic, and life experience variables, as well as speech recognition scores. A representative sample of 209 adults implanted between 1985 and 2006 participated. Using multiple linear regression models and generalized linear mixed models, sets of optimal predictor variables were selected that effectively predicted performance on a test battery that assessed different aspects of music listening. These analyses established the importance of distinguishing between the accuracy of music perception and the appraisal of musical stimuli when using music listening as an index of implant success. Importantly, neither device type nor processing strategy predicted music perception or music appraisal. Speech recognition performance was not a strong predictor of music perception, and primarily predicted music perception when the test stimuli included lyrics. Additionally, limitations in the utility of speech perception in predicting musical perception and appraisal underscore the utility of music perception as an alternative outcome measure for evaluating implant outcomes. Music listening background, residual hearing (i.e., hearing aid use), cognitive factors, and some demographic factors predicted several indices of perceptual accuracy or appraisal of music. La investigación examinó si el desempeño, por parte de adultos receptores de un implante coclear, sobre una variedad de pruebas de reconocimiento y evaluación derivadas de la música del mundo real, podrían predecirse a partir de variables tecnológicas, demográficas y de experiencias de vida, así como de puntajes de reconocimiento del lenguaje. Participó una muestra representativa de 209 adultos implantados entre 1965 y el 2006. Usando múltiples modelos de regresión lineal y modelos mixtos lineales generalizados, se seleccionaron grupos de variables óptimas de predicción, que pudieran predecir efectivamente el desempeño por medio de una batería de pruebas que permitiera evaluar diferentes aspectos de la apreciación musical. Estos análisis establecieron la importancia de distinguir entre la exactitud en la percepción musical y la evaluación de estímulos musicales cuando se utiliza la apreciación musical como un índice de éxito en la implantación. Importantemente, ningún tipo de dispositivo o estrategia de procesamiento predijo la percepción o la evaluación musical. El desempeño en el reconocimiento del lenguaje no fue un elemento fuerte de predicción, y llegó a predecir primariamente la percepción musical cuando los estímulos de prueba incluyeron las letras. Adicionalmente, las limitaciones en la utilidad de la percepción del lenguaje a la hora de predecir la percepción y la evaluación musical, subrayan la utilidad de la percepción de la música como una medida alternativa de resultado para evaluar la implantación coclear. La música de fondo, la audición residual (p.e., el uso de auxiliares auditivos), los factores cognitivos, y algunos factores demográficos predijeron varios índices de exactitud y evaluación perceptual de la música.

Abstract Background Music is a very important art form that can evoke strong emotions and involvement with it can have a considerable impact on cochlear implant (CI) recipients' quality of life. It is well known that music perception is limited in CI with fully electric hearing and CI recipients have significantly poorer music-appraisal ability when compared with normal hearing subjects. Considering the importance of music on the life of an adolescent and negative impact of hearing loss on mental health, understanding and improving music listening habits and perception abilities can have a positive impact on the mental health of CI user adolescents. Purpose This study aims to evaluate music listening habits and music perception abilities of prelingually deafened adolescent CI users to reveal the relationship between self-reported assessment and psychophysical measurement. Research Design The psychophysical measures of music perception and self-reported music listening habits of adolescent CI users were obtained. Study Sample Twenty-nine prelingually deafened adolescent CI users were evaluated in this study. Data Collection and Analysis The Turkish Clinical Assessment of Music Perception (T-CAMP) test was used to evaluate music perception abilities. These abilities were evaluated with a three-item questionnaire assessing enjoyment of music, listening habits, and comprehension of lyrics. Pearson's correlation coefficients were calculated to assess the relationship between the T-CAMP subtests and questionnaire items. Results Statistically significant correlations were observed between the melody-recognition subtest of T-CAMP and all three questionnaire items. The correlation between the enjoyment and rate items on the questionnaire was also statistically significant. Conclusion The present study shows that adolescent CI users also enjoy and listen to music in ways similar to postlingually deafened adult CI users. It also demonstrates that melody-recognition abilities have a significant relationship with music enjoyment and listening habits in prelingually deafened adolescent CI users.

Abstract Background Suture anchor placement for subscapularis repair is challenging. Determining the exact location and optimum angle relative to the subscapularis tendon direction is difficult because of the mismatch between a distorted arthroscopic view and the actual anatomy of the footprint. This study aimed to compare the reliability and reproducibility of the navigation-assisted anchoring technique with conventional arthroscopic anchor fixation. Methods Arthroscopic shoulder models were tested by five surgeons. The conventional and navigation-assisted methods of suture anchoring in the subscapularis footprint on the humeral head were tested by each surgeon seven times. Angular results and anchor locations were measured and compared using the Wilcoxon signed rank test. Interobserver intraclass correlation coefficients (ICCs) were analyzed among the surgeons. Results The mean angular errors of the targeted anchor fixation guide without and with navigation were 17° and 2° (p < 0.05), respectively, and the translational errors were 15 and 3 mm (p < 0.05), respectively. All participants showed a narrow range of anchor fixation angular and translational errors from the original target. Among the surgeons, the interobserver reliabilities of angular errors for ICCs of the navigation-assisted and conventional methods were 0.897 and 0.586, respectively, and the interobserver ICC reliabilities for translational error were 0.938 and 0.619, respectively. Conclusions The navigation system may help surgeons be more aware of the surrounding anatomy and location, providing better guidance for anchor orientation, including footprint location and anchor angle.

The objective of this study was to evaluate the efficacy of a prototype interactive music awareness program (IMAP) for adult cochlear implant (CI) users. An unblinded, randomized crossover design was used. Twenty-one CI users were recruited and allocated to two groups. Group 1 received the IMAP first, followed by a retention of learning phase. Group 2 were given the IMAP after 12 weeks. Participants were instructed to undertake two half-hour sessions per week at home over 12 weeks. Both groups attended appointments at the start, halfway through, and at the end of the trial. At each appointment participants completed tests of speech perception, melodic contour identification, and instrument recognition, rated the sound quality of music, and indicated their music listening habits. Sixteen participants completed the study. Following training both groups showed improved instrument recognition abilities and feedback suggests further positive impact on participants’ lives. The findings suggest that the IMAP is beneficial for music perception and in particular, improved instrument recognition.

Aim. The aim of this report is to identify variables determining the effectiveness of small football games at subsequent stages of training. Material and Methods. The study material comprised the results of tests conducted among 42 football players who were assigned to 3 categories: youngsters, younger juniors and seniors. The scope of the study included basic somatic features, selected motor skills tests and specific coordination tests of motor skills recommended for football players. Detailed correlation matrices were calculated using Spearman’s signed-rank test between all the analysed variables and the overall game perforance index (OPI). For each training group, morpho-functional profiles were calculated taking variables from previous analyses into account. Variables forming the structure of these models were normalised on the T scale. Results. 11 statistically significant Spearman’s signed-rank correlation coefficients were obtained between game performance indices and the analysed variables. In the 3 training groups of football players, considerable diversity of the internal structure of morpho-functional models was noted. In the group of juniors and seniors, differentiation between features was 1.2 of standard deviation. Conclusions. In terms of fitness, the influence of circulatory-respiratory endurance and speed ability on the indicator of overall performance for the seniors’ game was noted. In turn, taking the neuro-functional side of the players’ motor ability into account, correlations with the effectiveness of the game were mainly found within the ability of balance, kinesthetic differentiation and motor adaptation. Such regularities mainly refer to the youngsters and younger juniors.

Objective. To validate an audio-video (AV) method of food journaling, in a free-living scenario, compared to direct, weighed food assessment. Design and Setting. Data were collected in a cafeteria. Meals, selected by participants (n=30), were documented using the AV method: participants video-recorded their tray while audio-recording a description of their selected meal, after which the research team digitally weighed each food item and created an itemized diary record of the food. Variables Measured. Data from the AV method and from the weighed food diaries were transcribed and entered into a nutrition software analysis program (Nutribase Pro 10.0). Nutrient outputs were compared between the two methods including kilocalories, macronutrients, and selected micronutrients. Analyses. Using mean scores for each variable, Wilcoxon signed-rank test and Spearman’s correlation coefficients were conducted. Interclass correlation coefficient (ICC) was calculated for absolute agreement between the two methods to assess interrater reliability. Results. With the exception of Vitamin E and total weight, nutrient values were highly correlated between methods and were statistically significant given alpha = 0.05, power = 0.95, and effect size of 0.70. Conclusions. The AV method may be a meaningful alternative to diary recording in a free-living setting.

The article examines the possibility of forecasting the spring wheat the productivity according to the content of mobile forms of phosphorus, potassium, applied amount of mineral and organic fertilizers. Deviation of the projected yield from actual comes to 31%, and the forecasting yield of the moving average drops to 4.6%. During the observation period the spring wheat productivity increased from 11.6 to 18.7 kilogram per hectare, an increase was 7.1 tons per hectare with an average yield of 17.4 tons per hectare. The productivity of spring wheat exhibits a very unstable value, which is evidenced by the high variation coefficient - 43.3%. There is a positive correlation between security soil by phosphorus, potassium and spring wheat yield. It is positive according to phosphorus for the actual and derivative wheat yield, the higher rates of coefficients was according U11. Potassium also has a positive association with yield. However, the correlation coefficients of potassium are higher (0.57-0.0.94), than of phosphorus (0.50-0.84). This fact suggests, that potassium in macroelement is more scarce, than phosphorus. Apparently, this feature of mobile potassium is manifested by solubility characteristics of the potassium compounds in aqueous medium, despite a sufficient amount of its gross shapes in soils. Studies prove once again, that the basis of of productivity formation is security by nutrient macroelements and peculiarities of economic activities. In addition to more accurately actual spring wheat yield it is necessary to attract agro-climatic indicators. The projections data are also a good tool for assessing the economic activity of individual districts, regions, and land users of different levels.
