Abstract: The paper presents research background and basic theory and method of acoustic transmission loss in the shallow water. The effects due to sound transmission loss by shallow water environment are described through analyzing the transmis- sion loss with explosive sound signal at different frequency range filtered by third octave. With no priori knowledge, the nor- mal modes are successfully extracted from the sound pressure data derived from the vertical liner receiver arrays (VLAs). The comparison of normal modes extracted and calculated by Kraken Mode Model is also presented.
