The use of professional audio

　　Loudness is the intensity perception of practical listening, and it is directly related to the maximum sound pressure level target of the sound reinforcement system. For performance, only a satisfactory loudness can be fully reflected in the sound effect. The output power of the system and the placement of the speakers will directly determine the loudness status of the listening area: high definition.

　　When used as a lecture, the clarity of speech must be ensured. If people cannot hear the speaker clearly, it will affect the function of the lecture. Therefore, in the planning of the electro-acoustic system, we must fully consider the improvement of speech intelligibility: the fullness of satisfaction.

　　It has an outstanding fullness performance effect, which can make the vocals full and honest, and the music sound is melodious and active. In the electroacoustic system, only through the use of professional audio peripheral equipment to effectively process the sound signal and reasonable selection of speakers, the fullness of the sound can meet the requirements. The computer-aided planning of the acoustic characteristics of the sound reinforcement system is an ambitious method for engineering planning using modern technology. It has high precision and high efficiency. More importantly, the results of the project planning can be known without the completion of the device debugging. The acoustic characteristics computer planning system has very good reliability and accuracy. When the sound construction data input to the hall is accurate, the calculated data is compared with the final electroacoustic measurement results, and the error can be controlled within decibels. For engineering planning and device debugging, this has been met, and it also has a good planning device debugging guidance, which has been outstandingly verified in the previous sound engineering planning. Choosing an acoustic CAD computer system to plan the acoustic characteristics of the sound reinforcement system of the calculation hall, gymnasium (field), multi-function hall, and presentation hall means that there is no need to compare the system installation, debugging and measurement, and then you can know its planning and Professional audio equipment debugging results. In other words, according to the audio system and planning calculation results given in this planning scheme, the expected acoustic characteristics of the sound reinforcement system have been clearly seen. The acoustic characteristics not only meet the requirements of the national standards of the acoustic characteristics target, but also meet the requirements of one-sided listening, because of the acoustic characteristics target.
