Jiaxing Engineering Center of CAS Institute of Acoustics unveiled its latest research fruits on CIF 2008. The Electro-acoustic Parameters Detector attracted lots of experts and manufactures when it showed on the fair.

The Electro-acoustic Parameters Detector is a kind of device which can test many items of parameters, such as frequency response, sensitivity, harmonic distortion, impedance, polarity, T/S parameters in one test cycle rapidly and exactly. The device is supposed to be used in loudspeaker, receiver, multimedia speaker, earphone, microphone and others electro-acoustic devices or applied in real-time testing of a systematic product course to enhance the production efficiency and improve products quality. What's more important, this device owns a special function of sound quality detection. It can replace human beings in abnormal noise detection and recognize the quality of pure tone of electro-acoustic products subjectively and accurately. The application of this device can greatly increase the qualified rate of productions and decrease the hurt of frequency sweeping sound to workers' hearing and psychology. The interface of the device is designed both in English and Chinese, which is suitable to the users all over the world.
