Further research into crackling noise was done in the late 1940s by Charles Francis Richter and Beno Gutenberg who examined earthquakes analytically. Before the invention of the well-known Richter scale, the Mercalli intensity scale was used; this is a subjective measurement of how damaging an earthquake was to property, i.e. II would be small vibrations and objects moving, while XII would be ...

Impulse noise is a category of noise that includes unwanted, almost instantaneous (thus impulse-like) sharp sounds (like clicks and pops)—typically caused by electromagnetic interference, scratches on disks, gunfire, explosions, pickleball play, and synchronization issues in digital audio. High levels of such a noise (200+ decibels) may ...
Researchers said on Wednesday they have settled the issue of what occurs inside knuckles to trigger the familiar popping sound. Snap, crackle, pop: study reveals secret behind knuckle-cracking ...
Extreme cold causes stress cracks in windows to spread. Brown says he's not sure homeowners can do much to keep the cracks from elongating, but he does have some suggestions. Among them:
This makes a crackling sound, which has been compared to candy being unwrapped, Rice Krispies, or the sound of a log fire. This sound, first discovered by German physicist Heinrich Barkhausen, is called Barkhausen noise. Similar effects can be observed by applying only mechanical stresses (e.g. bending) to the material placed in the detecting coil.
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
In a rather innovative method, Audio Mentor took a user through a series of informative steps from setting the recording levels, noise reduction, sound enhancement to making a CD in minutes. It included facilities to automatically split a file into its individual tracks such as when transcribed from a cassette or LP record. In addition, it ...
