Some taxes are inadvertently hidden, but others are consciously designed that way to disguise the cost of government. Itâs easy to see why: the total U.S. tax burden is equal to 56 percent of annual personal consumption spending.
Thus, the volume is proportional to the amplitude of the sound wave. The frequency of a sound wave is perceived as pitch. Humans can detect pitches within the acoustic range of 20 to 20,000 Hz, but we can't detect ultrasound or infrasound.
In computers, hertz is a measurement of cycles per second. Megahertz is just a way to lower the number, similar to meter vs. kilometer.his originally pertained to radio waves and sound waves, but is now commonly used to measure the speed of a computer processor (the number of hertz is equal to the number of clock ticks that a processor will have in one second).
