This document comprises 11 chapters, including scope, normative references, terms and definitions, classification, overall requirements, teaching spaces, recording classrooms, public spaces, sports areas, construction, installation, testing and acceptance, operation and maintenance, as well as one annex for installing, accepting, and maintaining the audio system in schools. The main contents are as follows:
1. Classification of school audio systems
This document categorizes audio systems in detail from two perspectives: functional purpose and system stages. From a functional perspective, they are divided into sound reinforcement systems, recording broadcast systems, and broadcasting systems. From the perspective of system stages, they are categorized into pickup subsystems, amplification subsystems, and control subsystems.
2. Overall requirements
School audio systems should comply with GB/T 50526 and meet China's mandatory product certification requirements. They also require fire safety interfaces, software controls, speaker reuse, types of signal source devices, management methods for signal transmission, and applicable spaces.
3. Teaching spaces
(1) General requirements:隔声设计依据GB 50118—2010第5章的规定，并对教学空间进行分类。
(2) Specifies the microphone and audio system priority configuration in teaching spaces as well as relevant requirements for examination scenarios.
4. Recording classrooms
(1) General requirements:依据GB 50118的规定做好隔声设计，并做分区规划，尽量远离学校内外的主要噪声源。
(2) Specifies the microphone, speakers, and audio processors required in recording classrooms.
5. Public spaces
(1) General requirements:满足情景音乐和广播通知的扩声需求，对区域分类及覆盖做了要求。
(2) Specifies the speakers and power amplifiers required for public spaces.
6. Sports areas
(1) General requirements:对校园运动区的区域分类、选址以及噪音减排等方面做出规定。
(2) Specifies microphones, signal regulation and control equipment, power amplifiers, and speakers required in sports areas.
7. Construction, installation, testing, and acceptance
Based on GB/T 50526 and GB 50949, this document outlines the construction, installation, testing, and acceptance standards for school audio systems, considering the characteristics of school acoustic engineering验收。Acoustic system engineering performance tests must be completed after which the school organizes the acceptance.
8. Operation and maintenance
After passing the acceptance and being put into use, these documents specify regular maintenance requirements for the audio system.
