When a household light bulb is dropped overboard with a rock attached, it will self-implode at a depth of about 100 meters, producing an impulsive sound.  This recording is of such an implosion in 2400 m water depth where the echoes are distinctive corresponding to the water depth and hydrophone depth. Ocean acousticians sometimes use this technique as an inexpensive sound source.
