As Music Room in Art School is mainly for exercise of musical instrument rather than any lecture or music appreciation, it should be designed and constructed in consideration with Acoustic Condition on the preferential basis. However, in case of Music Room in Art School that has been built already or latest newly constructed, since it was designed and constructed without any reflection of Acoustic Characteristics, it appeared as inadequate for them to enjoy music appreciation or performance activity. On such view point, this Study has examined the physical Acoustic Characteristics for the subjects on those Music Rooms of Art Middle School, Art High School, Art College built in Cheonbuk Province, and it is deemed that the material grasped in such way could be utilized as the valuable data enables to improve Acoustic Performance at the time when designing and construction or renovation for Music Room hereafter.
