Direct-field acoustic testing, or DFAT®, is a technique used for acoustic testing of aerospace structures by subjecting them to sound waves created by an array of acoustic drivers. [1] The method uses electro-dynamic acoustic loudspeakers, arranged around the test article to provide a uniform, well-controlled, direct sound field at the surface ...
Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration. It includes the application of acoustics , the science of sound and vibration, in technology.
The angular spectrum method is a technique for modeling the propagation of a wave field.This technique involves expanding a complex wave field into a summation of infinite number of plane waves of the same frequency and different directions.
Acoustic theory is a scientific field that relates to the description of sound waves. It derives from fluid dynamics. See acoustics for the engineering approach.
Lindsay's Wheel of Acoustics, which shows fields within acoustics. Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.
Acoustic holography is a technique that allows three-dimensional distributions of sound waves called sound fields to be stored and reconstructed. To do this, sound passing through a surface is recorded as a two-dimensional pattern called a hologram (a type of interferogram). The hologram contains information about the phase and amplitude of the ...
An acoustic wave is a mechanical wave that transmits energy through the movements of atoms and molecules. Acoustic waves transmit through fluids in a longitudinal manner (movement of particles are parallel to the direction of propagation of the wave); in contrast to electromagnetic waves that transmit in transverse manner (movement of particles at a right angle to the direction of propagation ...
Aeroacoustics is a branch of acoustics that studies noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces. Noise generation can also be associated with periodically varying flows.
