Abstract

Two sound modes of superfluid 3He in aerogel are investigated using acoustic spectroscopy. The fast sound is a compression wave while the slow sound is the out-of-phase oscillation of the superfluid and the normal component. Superfluid fraction is determined by measuring the slow sound velocity.
