Detailed Product Description: | Henan the store stereo microphone Monopoly store audio Monopoly Jiaming Yang +65 +229 +631 1399 1300 +75250 Zheng * City Milan sun technology market, Building 5, Unit 2, 2082, terminology and related standards of professional sound engineering technology to learn audio engineering expertise you must first learn more about the technical terms and a number of countries and industry standards, the only way a professional design and construction to be targeted, the quality of the project can be fully guaranteed. Furthermore, all relevant professional and engineering standards and terminology is the basis of the work of the project is the design and construction of the basis and reference center. The following list must seriously study and understand the terminology and standards. SPL: refers to the actual sound pressure and the reference sound pressure ratio of 20 times the value is expressed in decibels. This is the mathematical expression. Its importance lies in: all audible sound system, the acoustic quality of sound reinforcement, the index in the back of the design calculations, it is a basis of calculation. Reverberation time: in a stable sound signal suddenly interrupted, the sound pressure level falls within the halls of 60dB the time required, in seconds. Its mathematical expression is as follows. It can be found, the reverberation time is closely related to the parameters and the structure and materials of the building decoration. In the actual project, the reverberation time hall building acoustics research indicators. PA power: rated PA sound pressure level system design, sound reinforcement equipment required rated power, in watts. This parameter is the actual sound regulation is not very important, but when the sound system design and selection, it is a direct manifestation of the acoustic indicators in the electro-acoustic parameters, and it related to the final cost of the project, so it particularly important. In engineering in general, it depends mainly on the rated power of the speaker to reflect. GB GB-3947, is a professional acoustic terminology explained: GB GB-4959, is a method of measuring the characteristics of the sound reinforcement; GYJ-25, the acoustic characteristics of the sound reinforcement system indicators. They are two important national standards, almost all of the works in the design, construction, acceptance need them as the basis; GB GB/T14218-93 electronic dimming device performance parameters and measurement methods; SJ2112-82 hall PA system equipment interconnected preferred electrical matching values. These two standards can play an important role in the selection of equipment and engineering test acceptance. We introduced several critical terminology and standards in the design and construction described is relatively simple, the main hope so reference, with the help of the books of these terms and standards for comprehensive learning, a careful analysis to understand them as the basis of engineering technology. In addition, there are other, due to the limited space here will not be described.
