Analysis And Reforms Of Acoustics Environment Of Existing Classroom In University

Architectural acoustic design has received more and more attention in architectural design technology.Scholars at home and abroad have made great achievements in the field of sound quality design and improvement of acoustic environment in buildings,and research methods and technical means are also developing.College classrooms are the most important place for teacher-student exchanges and student self-study.With the advancement of science and technology,traditional educational techniques and teaching methods are constantly innovating.Multimedia teaching has been widely used in universities and even primary and secondary schools,'virtual reality technology and augmented reality.Emerging technologies such as technology will gradually enter the classroom.In pursuit of a better audio-visual mode and advanced equipment,in order to match the advanced audio-visual means,the acoustic environment of the classroom interior itself cannot be ignored.Therefore,classroom acoustics has also become a research on building physical environment and architectural design.Hot spot.There are many objective physical parameters affecting the indoor acoustic environment of the classroom,such as background noise,reverberation time,sound field uniformity,language intelligibility,sound energy ratio,signal to noise ratio,etc.,it is necessary to first have sufficient understanding of the objective evaluation parameters.The research on the standards and norms of the design and renovation of college classrooms provides sufficient theoretical support and theoretical basis for improving the indoor acoustic environment of the classroom,and discovers that the traditional design concepts will have a negative impact on the acoustic environment of the classroom.To improve and transform the indoor acoustic environment of existing college classrooms,it is necessary to conduct on-the-spot investigations on the acoustic environment of the current classrooms,and select representative and universal classrooms for computational analysis,actual measurement,and computer simulation.The addition of the measurement results is related to the relationship between the subjective feelings of the classroom users and the objective evaluation parameters.Only by mastering the acoustic environment characteristics of the current classroom and understanding its acoustic defects can the acoustic environment transformation plan be more targeted.Based on the above research,the existing college classrooms are classified according to the key factors in the building acoustics,the indoor volume.This classification will be more conducive to the specific study of the classroom indoor acoustic environment,and through subjective and objective The study made reasonable recommendations on the limits of objective evaluation parameters for each type of classroom.With the continuous improvement of the field of architectural acoustics research,materials to improve the acoustic environment of the building are endless.It is necessary to understand the characteristics of various acoustic materials and conduct measurement experiments and analysis comparisons on their acoustic properties.Among the many materials,materials that are suitable for indoor use in the classroom and economical and beautiful,and a combination of various materials to form a key technology for the interior transformation of the university classrooms.Combining the above research results,four transformation plans and ideas are proposed.The analysis,calculation and simulation of each scheme are carried out.The improvement effect of the retrofit design scheme on the indoor acoustic environment under different layouts is tested.By comparing the ideas of each scheme and the relationship between them,In order to explore the best transformation effect and the best suitable indoor noise defects in the classroom for each program,and find the shortcomings of each progran and the acoustic environment problems that cannot be solved through the transformation plan.On the basis of the transformation plan,the key technologies of the indoor acoustic environment transformation of the existing college classrooms are applied and demonstrated,and the beneficial effects of each key technology are studied and analyzed through simulation.Finally,it 1s universally based on the application of the transformation plan and key technologies.The indoor acoustic environment transformation method of college classrooms provides reference for the transformation and design of classroom acoustic environment and other types of architectural acoustic environment in the future,and provides basis for the formulation and revision of relevant evaluation standards and specifications.
