WebTo measure a sound’s frequency, we use the hertz (Hz). Each time a sound’s decibel level increases by 10, its intensity multiplies by 10. However, the decibel scale is logarithmic, not linear. Therefore, a 10 dB sound is 10 times more intense than a 0 dB sound, a 20 dB sound is 100 times more intense, and a 30 dB sound is 1,000 times more ... WebMay 10, 2009 · Hertz (Hz) means the unit of cycles per second (1/T). It has to do with the frequency.
