由于采用“四模拟”技术使本振动仪成功地体现出骨导语言基本特性:人前额发话与振动仪的颅顶发话,两者语图极为相似;主观试听很难区分两者的差别。具有很强的新颖性和实用性。这是仿真测试技术一项新发展,是首创的模拟使用条件,对骨导送话器及其通讯帽的频响、灵敏度、信噪比参数,进行仿真测试较为理想的仪器。有条件时还可以作为计量标准仪器使用。 Due to the adoption of the “four simulations” technique, the vibrator successfully embodies the basic characteristics of the bone conduction: the pronunciations of the forehead speech and vibrator are very similar to each other; the subjective audition is hard to distinguish the two. Has a strong novelty and practicality. This is a new development of simulation test technology. It is the first instrument to simulate the conditions of use, the frequency response, sensitivity, signal-to-noise ratio parameters of bone conduction microphone and its communication cap. When conditions can also be used as a standard measurement equipment.
