Shear waves do not travel thru the air so they cannot be a part of your acoustic waves...
That is correct. They do propagate in any fluid, only solids. The guy arguing with you above is completely wrong.
As side from the obvious grammatical errors in your statement, "they do propagate in any fluid, only solids," any wave can propagate through a solid OR fluid. That is why we have shear waves and shear forces in air. And why there are shock waves in air. Apparently you fellers don’t know the difference between a force and a wave. Acoustic (sound) waves - the ones that travel through air - are mechanical waves, just like waves in solids. And sound waves travel through heavier liquids like water and even solids. In fact sound waves travel faster through heavier liquids and solids than through air. And that’s why, in terms of their effect on components, insomuch as they are mechanical waves, acoustic waves produce vibration in components. There is no difference - in terms of their *effect* - between the vibration produced by acoustic waves and the vibration produced internally by transformers, motors, etc. I consider this particular case closed.
