国际电工委员会第29技术委员会自1952年成立以来,就在次声、音频、超声频率范围内的电声和振动领域不断地拟订、修订国际标准。其内容涉及声音、通信、工业和计量应用、机械冲击和振动的产生与测量等方面的电气、电子设备和换能器的技术特性等,对标准计量、科研、生产、设计、外贸等均有很大的参考价值。现将该委员会至1980年止的所有现行标准公告介绍于后。
International Electrotechnical Commission Technical Committee 29 since its establishment in 1952, in the infrasound, audio, ultrasonic frequency range of electro-acoustic and vibration constantly developed and revised international standards. It covers the technical characteristics of electrical, electronic equipment and transducers for sound, communications, industrial and metrology applications, mechanical shock and vibration generation and measurement, etc. Great reference value. The committee now publishes all the current standard announcements up until 1980.
