👉 In physics and engineering, a non-acoustic object is an object that does not produce any sound when it is disturbed or subjected to pressure. These objects do not emit any audible noise during their operation, such as in a vacuum chamber, where no sound can be produced due to the lack of air resistance. Non-acoustic objects are often used in scientific research and engineering because they allow scientists to study phenomena that would otherwise be impossible to observe under normal conditions. They are also useful for studying objects that
