Abstract
Liquid **3He, despite the rather simple nature of its interatomic force, displays striking properties at ultralow temperatures. Below about 2 multiplied by 10** minus **3 K it behaves as a superfluid whose properties are related to, but are much more varied and complex than, those of superconducting electrons in metals. Ultrasonic waves prove to be a powerful probe of this system. Also presented is a brief review of the acoustic properties of both the normal and superfluid phases of this liquid.
