WebLouder sounds can cause immediate pain, and hearing loss can develop in a very short time. The TONE of sound is measured in cycles per second (cps) or Hertz (Hz): Low bass tones range around 50 to 60 Hz. Shrill, high-pitched tones range around 10,000 Hz or higher. The normal range of human hearing is about 20 to 20,000 Hz.
