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.
A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans.
