Resumen:

In this paper we describe an experimental method to obtain the acoustical parameters in phantoms using ultrasonic waves. The measurement technique is based on traditional pulse - echo method, with a single transducer placed at a distance of a acrylic container. The transit times of an ultrasonic pulse are measured at a high sampling rate by a digital oscilloscope. The distances between the transducer and the container was obtained at environment's temperature and pressure. This method is able to monitor some acoustical parameters in a phantom. © 2004 IEEE.
