Method for the acoustic characterization of underwater sources in anechoic tanks based on simulated free-field scenario

Underwater tanks for calibration are commonly used for transducer calibration and acoustic characterization. However, low frequency range is limited by tank dimensions and wall proximity to sound source. A possible solution may be to develop methods for underwater source characterization taking into account the reverberant field originated in the tank, but these methods are unable to solve source directivity. In this paper we show the development of a method for the acoustic characterization of underwater sources based on a simulated free-field scenario with absorbent material
