摘要
可控脉冲声信号在声学测量领域有着重要的应用。文中介绍了可控脉冲声信号的生成原理。选用DSP+CPLD作为硬件平台,详细介绍了可控脉冲声源的软硬件设计。最后通过实验对系统进行了验证。实验证明该系统可以产生能用于吸声与隔声测量的脉冲声信号。
Controllable sound impulses have important applications in the field of acoustic measurement.Based on the principle of sound impulses generation,a system constructed by DSP+CPLD was designed and implemented for controllable sound impulses generation.Experimental tests demonstrate the feasibility of generating desired sound impulses by this system.
