感性評価に基づいた図書館の音環境の開発方法の検討

抄録

In previous studies, genuinely silent sound environment was created using sound masking at a Polytechnic College library. In the research, one user commented “I can concentrate better when there is music that I like being played rather than being in a completely silent environment”. From these results, we suggest that the possibility is as follows. Sound environment that is “comfortable” for users improves their concentration and eventually promotes educational and research effects in library utilization. We conducted the preliminary investigation on recognition of Back Ground Music (BGM) in library. As a result, we confirm the following trends regarding recognition of BGM in college libraries.

・ BGM has the effect of enhancing concentration and relaxation for personal learning and reading.

・ Music focused on melody and harmony is preferable as BGM, whereas music focused on vocals is dispreferred.

Based on these results, we conducted an auditory experiment on BGM. In the experiments, users performed reading and calculation tasks in the library. The results showed that subjects found reading and numerical tasks easier to perform when there is BGM. In addition, no clear correlation was found between BGM that subjects found easier to work with and their personal taste in music. In this paper, we will discuss the preliminary survey described above and the auditory test. Subsequently, we will discuss developing a sound environment in a library that heightens users’ power of focus and promotes work.
