The described apparatus is a small portable sound and pressure-step generator capable of producting pressure levels of over 150 dB into cavities of maximum volume 30 cm3. The form of the pressure waveform is an exact replica of the electrical input waveform independent of leakage and flexibility in the cavity. Complex sound waveforms can be easily produced with the aid of a function generator.
所描述的设备是一种小型便携式声音和压力阶跃发生器,能够在最大容积为30立方厘米的空腔中产生超过150分贝的压力水平。压力波形的形式是电输入波形的精确复制,与空腔中的泄漏和柔韧性无关。借助函数发生器可以轻松产生复杂的声音波形。
