Acoustic Design for Urban Educational Buildings by Using Noise Tools, IBANA Calc and Ecotect

Abstract

Abstract Classroom is an integral part of learning activities in educational buildings. Learning in the classroom can be effective and focused if it has a good acoustic design. Unfortunately, most educational buildings are spread out in urban areas, which have a high noise level. This research aims to find the best acoustic design for educational buildings in urban areas. By using Noise Tools, IBANA Calc and Ecotect as simulation method, the research discusses the handling of acoustic design for educational buildings in urban areas through 3 (three) things. (1) Providing a barrier with a height of 2.5 m can reduce noise in the outdoor area of the building from 47.5 to 60.9 dB; (2) The use of block concreates materials, glass laminated and metal panels on the facade of the building, reducing noise to a level of 27dB; (3) The use of framed plaster board and suspended ceiling materials, providing an acoustic response with an estimated decay at all frequencies under 3 seconds.
