在脉冲测试中,传声器的传输性能可直接在屏幕或屏幕照片上看出,不需用复杂的仪器将其变换成频响。语言和音乐的瞬态过程在10到100毫秒的范围,而高质量传声器的瞬态过程有的不到1毫秒就结束了,所以传声器能拾取声音的精细过程。但许多只按最佳频响设计的传声器,所接收的声音与其固有振荡频率相重迭,使其得到幅度调制这种典型“音响”。所以,下述传声器脉冲状态的测试将是很严格的,即使在研制新式传声器时这只是问题的一个方面。
In pulse tests, the microphone’s transmission performance can be seen directly on the screen or screen shot without the need for complex instruments to convert it to loudspeakers. The transient process of speech and music is in the range of 10 to 100 milliseconds, and the high-quality microphone transient takes less than 1 millisecond to complete, so the microphones can pick up the fine process of sound. However, many microphones, which are designed for the best frequency response, receive the same sound as their natural oscillation frequency, giving them the typical “sound” of amplitude modulation. Therefore, the following test of the pulse state of the microphone will be very strict, which is only one aspect of the problem even when a new microphone is being developed.
