acoustics
Acoustics is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. 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 speech 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. Robert Bruce Lindsay's 'Wheel of Acoustics' is a well accepted overview of the various fields in acoustics.
The word "acoustic" is derived from the Greek word ἀκουστικός (''akoustikos''), meaning "of or for hearing, ready to hear"〔(Akoustikos ) Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', at Perseus〕 and that from ἀκουστός (''akoustos''), "heard, audible",〔(Akoustos ) Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', at Perseus〕 which in turn derives from the verb ἀκούω (''akouo''), "I hear".〔(Akouo ) Henry George Liddell, Robert Scott, ''A Greek-English Lexicon'', at Perseus〕
The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics〔(Kenneth Neville Westerman (1947) )〕 and later a branch of acoustics.〔(Theodor F. Hueter, Richard H. Bolt (1955) )〕 Frequencies above and below the audible range are called "ultrasonic" and "infrasonic", respectively.
