当固体撞击表面时，在空气中的麦克风和液体下方的水听器上记录的声音被记录下来，并与进入时形成的空腔的电影照片相关联。还测量了形成空腔的弹丸的底压。看来对声音的主要贡献来自腔的脉动。
The sounds, recorded on a microphone in air and on a hydrophone beneath the liquid, when a solid body strikes the surface are recorded and correlated with cine-photographs of the cavity formed on entry. Measurements of base pressure on a projectile forming a cavity are also made. It appears that the major contribution to the sound comes from pulsations of the cavity.
