Hello!
I built a model of acoustic interface which consists of a water domain and there is an obstacle(acrylic) inside. The transducer (PZT-5H) will transmitted a wave and will received it back after it hit an obstacle. I already received back the signal and represented it using point graph. However, there is something that I am unsure about. Can someone tell me whether there will be a reflection from inside of the obstacle? I mean is it supposed to be 2 signals from the obstacle, one from the wall and one from inside?
Thank you.
