Can sound waves be modified to impact a segmented object?

Question

Hello. I know that resonant frequency is the frequency at which an object vibrates. Segmented objects don't resonate well, because the sond waves tend to overlap and idssipate. Is there a way to modify sound waves so that the segmented object can shatter and/or implode? Please let me know. :D

Answer 1

Choose sound at the resonant frequency of one segment. If they resonate at different frequencies, slowly sweep the sound through the frequency range. But few object resonate enough for sound energy to do any harm.

Answer 2

To answer this you need to have a basic understanding of how and why resonance works and what standing waves are. The idea is that you regularly send a wave down a medium (lets say a string). Each wave bounces off the ring around a pole that the string is attached to and then returns. When the forward waves overlap they become bigger. Well, if you do something like this enough, you can create standing waves. This is where the wave doesn't go back down because you are constantly vibrating it.

The idea of resonance frequencies of an object is that the frequency is just right that each impulse gets bigger and bigger. There is a story of Tesla doing a lot of calculations to figure out the resonant frequency of his research facility. He put a very small electric hammer to a primary beam and had it strike at just that frequency. He came back hours later to find the entire building wobbling and collapsing.

I am not exactly familiar with the math of this but it is possible to find the right frequency of even a segmented medium. My suggestion is to find the frequency of each segment individually and then to overlap the sound waves. I believe that should get them to harmonize and get the effect you want.

btw, all objects are vulnerable to collapse from resonance. The problem is that objects are rarely subjugated to a consistent frequency that is in the precise range to collapse it. One of the notable cases where this is not true is in earthquakes. They tend to have frequencies very close to the resonance of buildings which is why they can vibrate and collapse. So, this is not some weak effect that shows up once in a while but rather a very powerful one that is apparent for all objects.

prob by modulation, also the energy can produce heat. fun book is "german secret weapons of WW2"
