The effects of background music on the work attention performance between musicians and non-musicians

For occupational safety and ergonomics, the relationship between work attention performance and background music is a trend for the future. Attention performance may be influenced by some personal factors, such as experience of music training. This investigation explores the difference between the attention performance of musicians and that of non-musicians based on a quasi-experimental design to gain a preliminary understanding of the possible effect of background music on the attention performance of both groups. This study found that a musician's attention performance is better than a non-musician's and that background music tends to improve the attention performance of both musicians and non-musicians, but to a greater extent for musicians.

Musical expertise and the ability to imagine loudness

Most perceived parameters of sound (e.g. pitch, duration, timbre) can also be imagined in the absence of sound. These parameters are imagined more veridically by expert musicians than non-experts. Evidence for whether loudness is imagined, however, is conflicting. In music, the question of whether loudness is imagined is particularly relevant due to its role as a principal parameter of performance expression. This study addressed the hypothesis that the veridicality of imagined loudness improves with increasing musical expertise. Experts, novices and non-musicians imagined short passages of well-known classical music under two counterbalanced conditions: 1) while adjusting a slider to indicate imagined loudness of the music and 2) while tapping out the rhythm to indicate imagined timing. Subtests assessed music listening abilities and working memory span to determine whether these factors, also hypothesised to improve with increasing musical expertise, could account for imagery task performance. Similarity between each participant's imagined and listening loudness profiles and reference recording intensity profiles was assessed using time series analysis and dynamic time warping. The results suggest a widespread ability to imagine the loudness of familiar music. The veridicality of imagined loudness tended to be greatest for the expert musicians, supporting the predicted relationship between musical expertise and musical imagery ability.
