摘要： An ultrasonic measurement device and method in which an ultrasonic transducer is acoustically coupled to an object to be measured by a resilient material contact layer. The transducer transmits a plurality of consecutive ultrasonic transmit signals into the object being measured, the transmit frequency of each of the plurality of transmit signals being distinct from the frequency of the other transmit signals of the plurality of transmit signals. Signal echoes of the transmitted signals are received, and based on the received signal echoes, at least one transmit frequency to be used for ultrasonic measurement of the object is selected.
