👉 The term "subconchoidal" is a scientific term that refers to a type of sound wave, specifically one that is produced by an object's vibrations. A subconchoidal wave is characterized by its frequency being lower than that of a normal conchoidal wave, which has the same amplitude but different frequencies. Subconchoidal waves are often used in the context of acoustics to describe the behavior of objects like glass or metal plates when they are struck with an acoustic source.
