【摘要】 人工嘴是一种模拟人嘴发声的声源,它被广泛应用于电声产品的测试当中。它声学特性的好坏直接影响整个测试结果,因此,对于人工嘴的声学特性校准是十分必要的。参照国际电信联盟和IEEE通讯协会起草的标准,通过作者日常试验情况,总结心得,与读者一起探讨人工嘴的校准方法。更多还原

【Abstract】 The artificial mouth is the source of a simulation of the mouth;it is widely used in electro-acoustic product testing.Its acoustic characteristics directly impact on the test results,so it is very necessary for the calibration of the acoustic characteristics of the artificial mouth.For readers’ reference,in this paper,the author introduce the calibration method of the artificial mouth reference the standards by ITU and IEEE Communications Society.更多还原
