<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; WORD-BREAK: break-all; LINE-HEIGHT: 150%; TEXT-ALIGN: left; mso-pagination: widow-orphan" align=left> 近几年来，随着我国经济的发展和人民生活水平的提高，各类歌舞厅的建设发展很快，对提高社会文化事业的发展起到了积极的促进作用。但是由于对歌舞厅在技术上没有提出声、光质量的
控制标准，致使一些歌舞厅的声、光污染很大。为了保证广大娱乐群众的健康水平，我部于一九九二年下达并委托江苏省文化厅科教处、北京市文化艺术科研所、
上海市舞台技术研究所起草制订了歌舞厅的声光质量
控制行业标准。１９９３年６月２９日我部教科司在北京主持召开了先期完成的“歌舞厅扩声系统的声学特性指标与测量方法”行业标准审定会。与会专家一致同意通过了该项标准。根据国家对行业标准治理办法的规定，现由我部正式发布并立即实施。希望各地文化主管部门积极组织专业队伍，会同当地有关部门对本地区的歌舞厅扩声系统的声学质量进行检查，并认真贯彻执行。 <BR><BR> 中华人民共和国文化行业 <BR> 标准歌舞厅扩声系统的声学特性指标与测量方法 <BR><BR> Ａｃｏｕｓｔｉｃａｌ ｃｈａｒａｃｔｅｒｉｓｔｉｃｓ ａｎｄ ｍｅ－ａｓｕｒｅｍｅｎｔ ｍｅｔｈｏｄｓ ｆｏｒ ｔｈｅ ｓｏｕｎｄ ｒｅｉｎ－ <BR>ｆｏｒｃｅｍｅｎｔ ｓｙｓｔｅｍ ｉｎ ｂａｌｌｒｏｏｍ ＷＨ０３０１－９３ <BR> １．主要内容与适用范围 <BR> 本标准规定了营业性歌舞厅的扩声系统的声学特性指标与测量方法。 <BR> 本标准适用于安装有扩声设备的各类歌厅、舞厅、卡拉ＯＫ厅和类似功能的厅。 <BR> ２．引用标准 <BR> ＧＢ３２４１ 声和振动分析用１／１和１／３倍频程滤波器 <BR> ＧＢ３６６１ 测试电容传声器技术条件 <BR> ＧＢ３７８５ 声级计电、声性能及测量方法 <BR> ＧＢ３９４７ 声学名词术语 <BR> ＧＢ４９５９ 厅堂扩声特性测量方法 <BR> ＧＹＪ２５ 厅堂扩声系统声学特性指标 <BR> ３．术语 <BR> ３．１ 扩声系统 ｓｏｕｎｄ ｒｅｉｎｆｏｒｃｅｍｅｎｔ ｓｙｓｔｅｍ <BR> 扩声系统由扩声设备和声场组成。主要包括：声源和它四周的环境，把声信号转变为电信号的传声器，放大电信号并对信号加工的设备、传输线，把电信号转变为声信号的扬声器和听众区的声学环境。 <BR> ３．２ 空场 ｖａｃａｎｔ ａｕｄｉｔｏｒｉａ <BR> 除必要的测量技术人员外，厅内没有观众和演员。测量时，厅内设置与相对应的满场正常使用时间完全相同。 <BR> ３．３ 最大声压级 ｍａｘｉｍｕｍ ｓｏｕｎｄ ｐｒｅｓｓｕｒｅ <BR>ｌｅｖｅｌ <BR> 厅内空场稳态时的最大声压级。 <BR> ３．４ 最高可用增益 ｍａｘｉｍｕｍ ａｖａｉｌａｂｌｅ ｇａｉｎ <BR> 歌舞厅扩声系统在声反馈自激临界状态的增益减去６ｄＢ时的增益。 <BR> ３．５ 声反馈 ａｃｏｕｓｔｉｃ ｆｅｅｄｂａｃｋ <BR> 由于扩声系统中扬声器输出的能量的一部分反馈到传声器而引起的啸叫声或衰变声。 <BR> ３．６ 传输频率特性 ｔｒａｎｓｍｉｓｓｉｏｎ ｆｒｅｑｕｅｎｃｙ <BR>ｃｈａｒａｃｔｅｒｉｓｔｉｃ <BR> 厅内各测点处稳态声压的平均值相对于扩声系统传声器处声压或扩声设备输入端电压的幅频响应。 <BR> ３．７ 传声增益 〔ｓｏｕｎｄ〕ｔｒａｎｓｍｉｓｓｉｏｎ ｇａｉｎ <BR> 扩声系统达最高可用增益时，厅内各测点处稳态声压级平均值与扩声系统传声器处声压级的差值。 <BR> ３．８ 声场不均匀度 ｓｏｕｎｄ ｆｉｅｌｄ ｎｏｎｕｎｉｆｏｒｍｉｔｙ <BR> 有扩声时，歌舞厅内各测点处得到的稳态压级的极大值和极小值的差值，以分贝表示。 <BR> ３．９ 背景噪声 ｂａｃｋｇｒｏｕｎｄ ｎｏｉｓｅ <BR> 当扩声系统不工作时，厅内各测点处室内本底噪声声压级的平均值。 <BR> ３．１０ 总噪声 ｏｖｅｒ ａｌｌ ｎｏｉｓｅ <BR> 扩声系统达到最高可用增益，但无有用声信号输入时，厅内各测点处噪声声压级的平均值。 <BR> ３．１１ 系统失真 ｓｙｓｔｅｍ ｄｉｓｔｏｒｔｉｏｎ <BR> 扩声系统由输入声信号到输出声信号全过程中产生的非线性畸变。 <BR> 注：当测量由声输入到声输出的非线性失真有困难时，答应测量由电输入到声输出的非线性失真作为系统失真，但应注明。一般常用谐波失真来近似衡量系统失真。 <BR> ３．１２ 混响时间 ｒｅｖｅｒｂｅｒａｔｉｏｎ ｔｉｍｅ <BR> 声源达到稳态，待停止发声后，室内声压级衰减６０ｄＢ所需的时间。 <BR> ４．歌舞厅扩声系统的声学特性指标 <BR> ４．１ 歌厅、卡拉ＯＫ厅扩声系统声学特性指标分为一、二级，具体指标见表１。 <BR> 表１ <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
