Acoustics is the part of physics dealing with sound. According to Wikipedia, "The word "acoustic" is derived from the Greek word ἀκουστικός (akoustikos), meaning "of or for hearing, ready to hear."Acoustics is etymologically the study of sound. Sound waves are mechanical waves - they travel by actual vibrations in some material medium. Acoustics concerns itself with mechanical waves in general. Phenomena such as forced vibrations, resonance, damped vibrations and Doppler effect come under this branch of physics.
