Normal curve of hearing
Web28 de jun. de 2024 · The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz. Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it’s the upper frequencies we lose first. So by the time we hit middle-age, we can expect to ... WebA normal distribution curve is plotted along a horizontal axis labeled, Trunk Diameter in centimeters, which ranges from 60 to 240 in increments of 30. The curve rises from the horizontal axis at 60 with increasing steepness to its peak at 150, before falling with decreasing steepness through 240, then appearing to plateau along the horizontal axis.
