Use of Reverberant Sound Fields for Metrological Studies in a Laboratory-Scale Hydroacoustic Tank

详细

A technique of free-field measurements intended for calibration of hydroacoustic transducers in a reverberant laboratory-scale hydroacoustic tank is described. The technique is based on the use of the reverberant fields of noise and linear frequency-modulated signals in combination with processing by means of complex moving weighted averaging. Results of tests performed by the technique in the reverberant noise field of a laboratoryscale hydroacoustic tank are presented.
