ACOUSTICS:

| ACOUSTICS |
A branch of physics
which deals with the process of generation reception and propagation of sound
is called “ACOUSTICS”.
In telecommunications,
an acoustic couplet is an interface device for coupling electrical signals by
acoustical means usually in to and out of a telephone instrument.

| ACOUSTICS & ULTRASONIC |
The link is achieved
through converting reconvert sound to electric signals needed for the end
terminal such as a teletypewriter and buck is a electrical connection.
Automatic acoustic
management is a method for reducing acoustic emanations in at attachment mass storage
devices for computer data storage, hard disk drives, etc....
The acoustic
management parameters are adjustable through a software or firmware user
interface.
ULTRASONIC:
Ultrasonic is a
developing and implementing data analysis methods can consume a significant
fraction of the time and effort required for “ULTRASONIC NDE” technique
development.
Computer software
required the majority of our time and often delayed us for a begin
experimenting with a new technique.
 |
| ULTRASONIC |
Implementation of
new data analysis methods must be easy and fast.
Software must be
easily expandable.
Digitize the
ultrasonic waveform.
Perform an FFT on these points.
The wave forms in the scan were operated on at a time.
The exact same operation was repeated on every waveform in the scan.
window out the magnitude point that corresponds to 450 kHz.
Display the image pixel that corresponds to this waveform.
