| 요약2 | It is often the case that various kinds of language listening tests are held in high school classrooms. Absorption material and loudness of speakers are the major variable factor of listening environment in the classroom. The absorption material in the classroom may influence the listening environment. So in this study, acoustical measurements were carried out in the classroom. According to the increase of absorption material and number of speakers, D50 value increases in all receiving point. And 0.1-0.13 D50 value was increased by attach the absorption material at both side wall. As the sound pressure level increased, so did the D50 value in all receiving point. But sound pressure level reach the certain limitation, D50 value was decreased. |
