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.
Best Answer: Hertz (Hz) is the name given to frequency in cycles per second in honor of a pioneer in the field. It is used in electronics, music and anything else that needs a measure of vibrational frequency. In music the pitch of the sound is a function of the frequency so the Hz defines the note.
