I Understanding Ultrasound Blocking: Effects on Energy, Reflection, and Absorption

TL;DR Summary

Ways of blocking ultrasound

Hello. I have a question in relation to blocking ultrasound. Suppose we have a device which emits ultrasound. Lets suppose that is is focused ultrasound, and it emits it towards a target at a displaced location. The question is, if you place an aluminum plate between the target location and the device, supposing further that the surrounding medium of the aluminum plate is air, what will happen with respect to the ultrasounds ability to reach the target point?

Suppose you characterize the ultrasound in accordance with various parameters such as frequency, intensity, energy and potentially other parameters. How much of the original ultrasound energy would reach the target point considering the aluminum plate that sits between the device and the target point? Include in your answer consideration of reflection as well as absorption and any other mechanisms for the interaction with the ultrasound.

That doesn't sound like a question you came up with. You should post it in the homework forum with an attempt at a solution.
