In AE testing, what is the most common frequency range
used for detecting signals?
100 to 300 kHz
Which type of discontinuity is least likely to be detected by
AE testing?
Rounded inclusions
The total energy loss of a propagating wave is called:
attenuation.
The Kaiser effect refers to:
the behavior where emission from a source will not
occur until the previous load is exceeded.
The Felicity effect is useful in evaluating:
fiber-reinforced plastic components.
The Kaiser effect is useful in distinguishing:
mechanical noise from growing discontinuities.
The term “counts” refers to the:
number of times a signal crosses a preset threshold.
The AE signal amplitude is related to:
the intensity of the source.
Threshold settings are determined by the:
background noise level.
Background noise can be reduced by:
electronic filtering.
