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.
How to Convert Megahertz to Hertz. Hertz are the international unit of measurement for frequency. Megahertz are larger units of frequency measurement that often apply to radio waves; each megahertz is equal to 1 million hertz. Multiplying by 1 million is often the easiest way to convert megahertz to hertz but may not always be the most appropriate.
