Xue Shao-jun · Audio Engineering · 2010
The impulsive sound is often used in actual measurement, the mobility of the impulsive sound source is very important. A generating techology of impulsive sound with controlled frequency is discussed, the designing proposal and the generating principle of the impulsive sound are introduced. The impulsive sound source device of impulsive sound is designed, which can produce the impulsive sound signal with different frequencies and different phonating time.
