Abstract: A method and system is disclosed for measuring a wideband loop sensitivity SL(f) for an acoustic transducer in an acoustic probe. A pulse signal is employed as a wideband reference signal Vr(t); and, in a pulse-echo measurement a corresponding wideband echo signal Ve(t) is obtained. A normalized loop frequency response {circumflex over (X)}(f) for the acoustic transducer is defined as a ratio of a Fourier Transform of the Ve(t) to a Fourier Transform of the Vr(t). A wideband loop sensitivity SL(f) for the acoustic transducer is defined as an absolute square of the {circumflex over (X)}(f) in decibel.

Abstract: A method and system is disclosed for measuring a characteristic loop sensitivity (SLC) for an acoustic transducer. A pulse signal is employed as a wideband reference signal Vr(t); and, in a pulse-echo measurement a corresponding wideband echo signal Ve(t) is obtained. A characteristic loop sensitivity (SLC) for the acoustic transducer is defined as a ratio of an energy density of Ve(t) to an energy density of Vr(t) in decibel, in which the energy density of a given signal is calculated as a ratio of an energy of the signal to a bandwidth of the signal.
