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. WebAt low frequencies, between 250 and 1,000 Hz, the loss of hearing is almost identical among men and women. In these frequencies the average hearing loss increases from 22-25 dB among those aged between 60 and 64 to 38-48 dB in the highest age group. A different pattern is found in high frequencies of 2000-8000 Hz, with men suffering much …
