Measurement And Study Of Indoor Acoustics Environment Of Different Functional Types

Taking concert hall and studio of Xinjiang Normal University as an example, thepaper is a theoretical explaination and practical verification for its objective acousticparameters,explore the two different types of sound quality of the room acousticsenvironment.Theoretical explaination present in first part and the second part.The first part is theintroduction,author starts from the Definition of room acoustics, to introduce somecommon room acoustics environments and expand the full text with highlight theimportance of the concert hall and studio. By comparison of the sound propagation inthe open space and indoor space and acoustic characteristics in the two kinds ofspace environment,this part expounds the value and significance of room acousticsresearch. At the same time,this part aslo sums up history and currentsituation,research results and reference standards of room acoustics developped inChinese and foreign,the common Sound absorption material is classified andexplained as absorption coefficient and characteristic differences. The second partintroduces the measurement apparatus and setting method, and expounds themeasurement method and works.Practical works are included in the third to fifth parts. the third part is mainlyinterpret the field measurement process of the concert hall and studio.According tothe characteristics of two kinds of indoor environment, using noise truncationmethod and pulse method. The fourth part is the data analysis and the sound fieldvalidation analysis by computer simulation. The fifth part is the overall evaluation ofacoustic environment respective on the concert hall and studio.Put forward feasiblesuggestions according to the results of the analysis.The conclusion is that: Room acoustics and acoustic design are inseparable,it’sessential that matching of the music and the corresponding room environment.Concert Hall carrying real-time performance for the audience and the studio is usedto record audio as the carrier, Analysis of objective acoustic parameters measuredon-site determines whether they meet the application requirements,which is animportant objective basis for feasibility of modification. At the same time, people’ssubjective evaluation is also important factors that determine the interior soundquality.This dissertation also puts forward that through analysis of the two kinds ofindoor environment, Trying to touch the most basic level of room acoustics and use itas a starting point, the other types of indoor acoustic environment or open sound fieldwill be made of study.
