A thousand vibrations a second, the unit of things buzzing too fast to see but not to hear.
means A unit of frequency equal to one thousand cycles per second, used to measure how often something oscillates — like radio waves or sound pitch.
from Built from the metric prefix 'kilo-' (Greek 'khilioi', meaning a thousand) plus 'hertz', named after the German physicist Heinrich Hertz, who in the late 1800s proved that electromagnetic waves travel through space as predicted by Maxwell's theory. His name became the unit for cycles-per-second in the early 20th century as electrical science formalized its vocabulary; 'kilohertz' simply scales that tribute up a thousandfold.
