　　The tetrahedral and orthogonal probes' sound intensity accuracy was compared according to the numerical calculation of the relative positions.The bias of amplitude and direction angle were also compared between tetrahedral and orthogonal probes under different conditions.The results show that orthogonal probe referring to the center of the circumscribed sphere has higher accuracy in amplitude.When ka is less than 0.9, The bias of the direction angle can be controlled within 2°and they can be used in the architecture acoustical measurement.
