The spin polarized hydrogen atoms (H↓) are treated as a weak interacting Bose-Einstein system. On the basis of Isihara's finite temperature theory and hard-sphere approximation, the possibility of gaseous superfluid and two modes of sound have been discussed. The importance of acoustical measurement technique in study on H↓ system is emphasized.
