Acoustic energy is sound energy produced by vibrating objects. The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing. Sound pressure is the effect and sound power (energy) is the cause. But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.
Polygenic inheritance. Definition. noun. A non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes. Supplement.
Polygenic inheritance refers to any trait, such as human skin color, that can be expressed in varying gradients because it is influenced by multiple genes. Early Mendelian genetics focused on simple traits that could be explained by a single gene.
