The acoustic characteristics of professional audio not only meet the requirements of national standards for acoustic characteristics indicators, but also meet the requirements of subjective listening sound, because acoustic characteristics indicators cannot fully reflect the actual sound effects, and the quality of sound is ultimately by the subjective listening sound sensation. Decided that when designing acoustic design, the electronic sound and building sound design should be well cooperated to meet the following subjective listening requirements: the appropriate loudness.

The loudness is the intensity of the actual listening sound. It is directly related to the maximum voltage -level indicator of the soundproof system. For the performance, only if it achieves sufficient loudness can the sound effect be fully expressed. The output power of the system, the position of the speaker, etc. will directly determine the loudness of the sound area: high resolution.

When used as a speech, it is necessary to ensure the understanding of the language. If people cannot hear the language of the speaker, it will affect the effect of the speech. Therefore, in the design of the electro -sound system, it is necessary to fully consider increasing the language understanding: enough plump.

It has a good full performance effect, which can make the sound full, strong, and the music is melodious and active. In the electro -sound system, the sound signal can only be effectively processed and reasonably selected by the audio signal through the use of audio peripheral devices to meet the requirements of the sound. The acoustic acoustic acoustic feature computer auxiliary design is an ideal method to use modern technology to engage in engineering design. It is high and efficient. More importantly, you can know the engineering design results without waiting for installation and commissioning. The acoustic characteristic computer design system has very good credibility and accuracy. When the sound data of the input hall is accurate, the calculation data is compared with the final electro -sound measurement result, and the error can be controlled within the decibel. For engineering design and installation and debugging, this is enough, and it also has good design installation and debugging guidance, which has been well verified in previous engineering design. The use of acoustic CAD computer systems to design computing halls, gymnasiums (fields), multi -functional halls, and lecture hall soundtracking systems, which means that after the system installation, debugging and measurement Debug results. In other words, according to the audio system and design calculation results given by this design plan, it has clearly seen the acoustic characteristics of the sound expansion system expected by the system.
