The Acoustics Design And Research On Digital Conference Hall

Under the direction of the Sciences of Auditorium Acoustics, the paper researches on the Auditorium Acoustics of the digital conference hall. On the basis of analysising the theory background, the paper researches on the practical construction project.The basic task of is to study the physical conditions of interior acoustic wave transmission and acoustic processing method approach to ensure a good indoor heard. Design options include selecting and confirming the type and volume, the best reverberation time and frequency response characteristic, layouting the acoustic materials and designing appropriate reflectors to organize the reflection rationally. There are not only sound absorption and reflection on the sidewall, ground, ceilings etc., but also sound absorption and voice scattering on various obstacles (wall decoration, audience, benches, etc.)in the conference hall. The combined result of the absorption, reflection and scattering has a significant change in voices heard by the audience. The auditorium acoustics design of the digital conference hall is to study these absorption, reflection and scattering patterns and their impact on the interior sound field, thereby improving the design to get the best quality evaluation, preventing interference of sound and sound focusing, to the widest possible that the audience will have the best hearing enjoyment.The innovation of the paper is that, not only researching from a theoretical point of the auditorium acoustics design of the digital conference hall, but also studying and testing the practical works from the perspective of the practical application of the auditorium acoustics design of the digital conference hall, attempting to find out the general method to auditorium acoustics design of the digital conference hall, approaching to more operability to acoustics design.As the auditorium acoustics design has a close relation to the shape and inside surface treatment of the hall, it should also be designed from the architectural perspective. To achieve excellent effect that unitying of acoustics function and architectural art to a high degree, acoustics designer and architects should work together for the same goal.
