Research on indoor noise evaluation and renovation design of university library--Taking the library of Wushan campus of South China University of Technology as an example

Abstract

Due to the special use requirements of university libraries, the requirements for indoor acoustic environment quality are relatively high. By investigating the layout and structural design of the library on the Wushan campus of South China University of Technology, distributing questionnaires to users and conducting on-site monitoring, fiunally found out the problems of the library, such as the sound of the upper and lower floors was connected, noise of friction with the ground when walking, keyboard tapping, moving seats, flipping and rummaging books, air conditioning and ventilation equipments and the low voice of speech had a greater impact on users, moreovernear the toilet and the elevator was noisy, the actual measurement of the sound level meter showed that the intermittent noise exceeded 55dB (GB 37488-2019 Hygienic indicators and limits for public places stipulates that the noise limit of the library is 55dB). Based on the above problems, the corresponding renovation measures are put forward, in order to provide technical references for the design and transformation of the acoustic environment of other domestic university libraries.
