Acoustical engineering is the branch of engineering dealing with sound and vibration. It is closely related to acoustics, the science of sound and vibration. Acoustical engineers are typically concerned with: Engineering is the applied science of acquiring and applying knowledge to design, analysis, and/or construction of works for practical purposes. ... Sound is a disturbance of mechanical energy that propagates through matter as a wave. ... Oscillation is the variation, typically in time, of some measure as seen, for example, in a swinging pendulum. ... Acoustics is a branch of physics and is the study of sound (mechanical waves in gases, liquids, and solids). ...

The art of reducing unwanted sounds is called noise control. Noise control engineers work with engineers in most industries to ensure that their products and processes are quiet. Noise Control: Building Interior Noise Control Reduction of Reverberation is one function of noise control, most often refered to when speaking of building and room interiors. ...

The art of producing useful sounds includes the use of ultrasound for medical diagnosis, sonar, and sound reproduction. Ultrasound is a form of cyclic sound pressure with a frequency greater than the upper limit of human hearing, this limit being approximately 20 kilohertz (20,000 hertz). ... This article is about underwater sound propagation. ... Sound reproduction is the electrical or mechanical re-creation and/or amplification of sound, often as music. ...

A separate and related discipline, audio engineering, is the art of recording and reproducing speech and music for human use. Audio engineering is a part of audio science dealing with the recording and reproduction of sound through mechanical and electronic means. ...
