Abstract We present a new geoacoustic inversion approach based on the stable inversion of sediment acoustic impedance from normal incident reflection data. The Hamilton empirical formulae are utilized to separate the impedance into velocity and density. The inverted results are evaluated by the measurement on the core samples. The predicted transmission losses (TLs) using the inverted results are in good agreement with the measured TLs from the explosive sources.
