The students from three universities (Groningen, Oldenburg and the University of Applied Sciences in Utrecht) were surveyed on the experience of hearing and listening in their studies. Included in the online survey were established questionnaires on hearing loss, tinnitus, hyperacusis, a subscale on psychosocial strain resulting from impaired hearing and a questionnaire about students’ perceptions of listening ease in study environments. Results from the 10,466 students who completed the survey (13% response rate) are highlighted, with particular attention to listening ease and measures proposed by students for improving it. The number of students having problems with hearing and listening transpires to be substantially larger when research is not constrained to students with a recognised hearing impairment, suggesting that listening is primarily a sociocultural performance and achievement rather than an artefact of physical attributes. One finding from our survey is that classroom practices could be more effective if study soundscapes are improved, while universities might exercise greater inclusive responsibility for study as a high quality sensory experience for the benefit of all students. 相似文献

This study examined the influence of physical exercise on the relation between shooting accuracy and the phase of the cardiac cycle in which the shot is fired. Thirteen experienced biathletes (8 females, mean age 17 years) fired from the standing position at rest and right after a submaximal exercise on a bicycle ergometer. Shooting accuracy and the timing of each shot relative to the R-waves of the electrocardiogram (ECG) were recorded. Best shots (with greatest accuracy) and worst shots (with lowest accuracy) were fired prevalently in different phases of the cardiac cycle. In the rest condition, best shots were fired less frequently from 200 to 300?ms and more frequently from 500 to 600?ms after the R-wave, compared to worst shots. In the exercise condition, best shots were fired less frequently from 100 to 200?ms after the R-wave and from 20% to 30% of the R-R interval, compared to worst shots. These findings support the hypothesis that shooting accuracy is influenced by the cardiac cycle phase due to the ballistocardiac recoil generated at each heartbeat. To achieve best results athletes could be trained (e.g. through biofeedback) to fire within a specific phase of the cardiac cycle. 相似文献
