WebFrequency is the number of cycles per second. The unit used to measure frequency is named hertz, which is defined to be the number of cycles in one second. (The hertz unit is named after Heinrich Hertz, a famous 19th century physicist.) The following video shows a high frequency wave and a low frequency wave, plotted as pressure versus time. Webfrequency, determines the interpretation of the loudness. At equal sound pressures, low frequencies are perceived as less loud than middle frequencies in the 1,000 to 4,000 …
WebThe frequency of any vibration is defined as the number of complete vibrations made each second: the frequency (hertz) is equal to the number of vibrations per second. Sometimes a complete vibration is referred to as a cycle: the frequency (hertz) is equal to the number of cycles per second.
