| Abstract: | The testing of acoustical specifications for public address system is an attempt and there is not corresponding national standards or codes for reference so far. According to the stipulation of "technical code for public address system and engineering", speaker zones in several public address system engineering and conduct testing on the spot are selected. In this article,several main acoustical specifications combining the stipulation of "technical code for public address system and engineering" are discussed. |
