acoustic image

acoustic image

[ə′küs·tik ′im·ij]
(acoustics)
The geometric space figure that is made up of the acoustic foci of an acoustic lens, mirror, or other acoustic optical system and is the acoustic counterpart of an extended source of sound. Also known as image.

In time domain imaging, where the echo amplitudes are recorded at a particular depth, solid-to-gas interfaces stand out in the monochrome acoustic image because they are white, and are typically much brighter than solid-to-solid interfaces, which typically reflect 20% to 80% of the ultrasound and are gray.

The Bluefin robot will build up a detailed acoustic image of the area using 'sidescan' sonar, hoping to repeat its success in finding an F-15 fighter jet which crashed off Japan last year.

The robot, which takes two hours to descend and another two to return to the surface, as well as several hours to download data, will build up a detailed acoustic image of the area using "sidescan" sonar.
SoundClear Music includes 3D spatial expansion to enlarge the acoustic image beyond the physical speaker and dynamic range control removes output distortion.
For this purpose, non-destructive control techniques more and more often use ultrasonic echoscopy systems where an acoustic image is modelled by scanning two-dimensional objects of investigation and selecting real time signals.
The photo on the cover of this month's issue shows the acoustic image of an MLCC that contains a single void.
Each 'echo' was really the sum of up to 4,000 reflections, producing an 'impulse response' representing an acoustic image.

If we can do a better job of imaging the target acoustically and identify it with a sonar, then get a really good acoustic image from 200-300 feet away, you could differentiate, for example, a piece of pipe from a torpedo or a lost bomb, or a 55-gallon drum," says Salmon.
The ultrasound pulsed into a component is reflected from material interfaces at many depths, but the echoes can be selected by their arrival time to limit the acoustic image to a desired depth.
