Impulse noise is a category of (acoustic) 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, and synchronization issues in digital audio. High levels of such a noise (200+ decibels) may damage internal organs , while 180 decibels are enough to damage human ears. WitrynaNowa seria podręczników dla współczesnych nastolatków.
