Audio equipment experts talk about the acoustic characteristics of the stage sound reinforcement system
Acoustic characteristics must not only meet the requirements of national standards for acoustic characteristics, but also meet the requirements of subjective listening, because the acoustic characteristics can not fully reflect the actual sound effects, and the sound quality is ultimately determined by the subjective listening feeling.
In acoustic design, electroacoustic and acoustic design should be well matched to meet the following subjective listening requirements:
1. The appropriate loudness loudness is the intensity perception of the actual listening sound. It is directly related to the maximum sound pressure level index of the sound reinforcement system. For the performance, only enough loudness can be achieved to fully realize the sound effect. The system output power, the position of the speaker, etc. will directly determine the loudness state of the listening area.
2. High definition
When used as a speech, the clarity of the language must be guaranteed. If people cannot understand the language of the speaker, it will affect the effect of the speech. Therefore, in the design of electro-acoustic systems, full consideration should be given to improving speech intelligibility.
3. Enough fullness
The performance of the performance with good fullness can make the voice full and rich, and the music is melodious and active. In the electroacoustic system, only by using the audio peripheral equipment to effectively process the sound signal and rationally selecting the speaker, the fullness of the sound can meet the requirements.
Sound Acoustic System Acoustic Characteristics Computer-aided design is an ideal method for engineering design using modern technology. It has high precision and high efficiency. More importantly, it is not necessary to wait until the end of installation and debugging to know the engineering design results. Acoustic characteristics The computer design system has very good credibility and precision. When the input data of the input hall is sufficiently accurate, the calculated data is compared with the final electroacoustic measurement result, and the error can be controlled within decibels. This is sufficient for engineering design and installation and debugging. At the same time, it also has good design, installation and debugging guidance, which has been well verified in previous engineering design.
The acoustic CAD computer system is used to design the acoustic characteristics of the audit hall, stadium (field), multi-function hall, and lecture hall sound reinforcement system, which means that it is not necessary to wait until the system is installed, commissioned and measured, and then the design and installation can be known. Debug results. In other words, according to the audio system and design calculation results given in this design scheme, the acoustic characteristics of the sound reinforcement system expected by the system are clearly seen.
