摘要
介绍了即将颁布的公共广播国家标准《公共广播系统工程技术规范》中关于"应备声压级"和系统音质评价的规定。针对电声学界的争议,论述了不应以声压级高低排质量档次的主张。对系统音质评价规定进行了适当的讨论。
The ensured sound pressure level in the pending national standard and the technical specifications in public address system are introduced. The standard to evaluate the project quality is elaborated. The acoustic criterion terms in the pending national standard and the technical code of public address system engineering are introduced and discussed.
