About Acoustics

The word “acoustic” is derived from the Greek Greek word á¼€κουστικÏŒς (akoustikos), meaning “of or for hearing, ready to hear and that from á¼€κουστÏŒς (akoustos), “heard, audible”, which in turn derives from the verb á¼€κούω (akouo), “I hear. The Latin synonym is “sonic”, after which the term sonics used to be a synonym for acoustics and later a branch of acoustics. Frequencies above and below the audible range are called ultrasonic and infsonic, respectively.

Acoustics is the branch of physics concerned with the study of sound of mechanical waves in gases, liquids, and solids including topics such as vibration , sound , ultrasound and infrasound. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing is one of the most crucial means of survival in the animal world, and speach is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or marking territories. Art, craft, science and technology have provoked one another to advance the whole, as in many other fields of knowledge.
