I know that aluminum is a highly effective reflector of ultrasound when the surrounding medium is air. However, I am particularly interested in how the described arrangement impacts the reduction in intensity as you consider the various mechanics of what is happening, namely the internal...
Furthermore, I believe you make reference to different kinds of ultrasound. With respect to all such types, are you able to answer the question taking into consideration my previous reply?
It seems like a rather simple question. In pure physics terms, explain the mechanics of the interaction of a focused ultrasound beam with such an arrangement purely as a function of attenuation due to reflection and absorption and the resultant intensity reduction without regard to anything else...
Hello. I write this in regards to enquiring whether you can address various questions I have in relation to acoustics and the physics of sound. In particular, I am interested in ultrasound. I have various questions in relation to it.
In particular, I am interested in understanding the nature...
The solution involves understanding the interaction between the ultrasound and the aluminum plate. One factor to consider is the acoustic impedance mismatch which will cause reflection of a proportion of the ultrasound energy. There may be other factors to consider.
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...
The question fundamentally is what in a pure physics sense causes the quantity of measurement. Can we describe it as a function of specific components that are well defined and with reasonable description. Therefore, I am not concerned with your notion of it being a tiny magnetic field, nor do...
First, I know where the magnetic sensor is in the smartphone, and so I hold the phone taking that into consideration when trying to measure an object. Thirdly, if it contained magnetic materials that interacted with the measurement then would you expect large increases in measurement to be...
I can confirm that I am using a smartphone the a magnetic sensor to perform the measurement. I did some quick research and it seemed as though smartphone magnetic sensors typically measure in DC and so I reasonably assumed this to be the case with my smartphone.
I would just like to clarify...
