Acoustic characteristics amplification system of computer aided design is the use of modern technology is engaged in the engineering design of a kind of ideal method, high accuracy, high efficiency, more important is do not need to wait until the end of the installation can know engineering design results. Acoustic characteristics of computer design system has very good credibility and precision, in the entry hall built sound data accurate enough, the calculation data compared with the last acoustic measurements, error can be controlled within the db. For engineering design and installation and debugging, this is enough, at the same time it also has the very good design installation guide, the in the engineering design of the past to get a good verification. Acoustic CAD computer system is used to design halls, gymnasium (field), multi-function hall, hall acoustic characteristics of the sound reinforcement system, means, do not need to wait until the system after the installation, debugging, and measuring, can know the design and installation debugging result. According to this design scheme is given, in other words, the audio system and the design and calculation results, has clearly see the expected amplification system acoustic properties.
