Abstract
This paper involves the acoustical design and measurement of sound quality in the new 316 classroom in TYUT. Based on the “Code for design of sound insulation of civil buildings” GBJ118-2010， this paper deals with the acoustical design of the frequency characteristics of reverberation time in the new 316 classroom in TYUT. Before the acoustical design in new 316 Classroom, the measurement of reverberation time (T20, T30, EDT) with frequency 500-1000Hz in empty room are 3.86-4.72s; After the acoustical design that the perforated wooden sound absorption tablet wall within glass wool sound absorption and the gypsum -slab mineral wool board ceiling are mounted in new 316 Classroom in TYUT, the measurement of reverberation time (T20, T30, EDT) with frequency 500-1000Hz in empty room are 0.72-0.82s.Through the checking of the testing data and the evaluation of the users, the acoustical design of the new 316 classroom in TYUT is in accordance with the requirements of Code for design of sound insulation of civil buildings GBJ118-2010.
