Acoustical engineering is the branch of Engineering is the application of science to the needs of humanity. This is accomplished through knowledge, mathematics, and practical experience applied to the design of useful objects or processes. Professional practitioners of engineering are called engineers. Compared to other professions to solve a problem, and how to implement that solution... engineering dealing with A schematic representation of auditory signaling Sound is a series of mechanical compressions and rarefactions or ) indicates a compression and the lower part (the is the displacement of particles from the stable position . The amplitude is the magnitude of sound pressure change within the wave. It is the maximal displacement... sound and Oscillation is the periodic variation, typically in time, of some measure as seen, for example, in a swinging pendulum. The term on the mass, tending to bring it back to equilibrium. However, in moving the mass back to the equilibrium position, it has acquired inertia which keeps it moving beyond... vibration. It is closely related to Acoustics is a branch of physics and is the study of sound, mechanical waves in gases, liquids, and solids. A scientist who works in the field of acoustics is an acoustician. The application of acoustics in technology is called acoustical engineering. There is often much overlap and interaction between the... acoustics, the science of sound and vibration. Acoustical engineers are typically concerned with:

  • how to reduce unwanted sounds
  • how to make useful sounds
  • using sound as an indication of some other physical property

The art of reducing unwanted sounds is called Active noise control (also known as noise cancellation or antinoise) is a method for preventing unwanted sound. Sound consists of vibrations in the air, which can be represented as a wave. If a speaker emits a sound whose wave has the same amplitude and the exact opposite phase to the... noise control. Noise control engineers work with engineers in most industries to ensure that their products and processes are quiet.

The art of producing useful sounds includes the use of Ultrasound is sound with a frequency greater than the upper limit of human hearing, approximately 20 kilohertz. Some animals, such as dogs, dolphins, and bats, have an upper limit that is greater than that of the human ear and thus can hear ultrasound. Ultrasound has industrial and medical applications. Medical... ultrasound for medical diagnosis, The F70 type frigates (here, to the effect that military sonar may be inducing some whales to experience decompression sickness (and resultant beachings). High-powered sonar transmitters can kill marine animals. In the Bahamas in 2000, a trial by the US Navy of a 230 decibel transmitter in the frequency... sonar and of course Sound reproduction is the electrical or mechanical re-creation and/or amplification of sound, often as music.

However, audio engineering is focused on the process of generating sounds, and concerns itself less with the effects of sound in a given space.
Audio engineers are generally familiar with the design, installation, and/or operation of sound recording, sound reinforcement, or sound broadcasting equipment.
Traditionally an audio engineer is responsible for the technical aspects of a sound recording or other audio production and works together with a record producer or a director.
