Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigati… WebFor an adult, 'normal' hearing ranges from 0 - 20 decibels (dB) in all frequencies, and 0 - 15 dB for a child. Above 20 dB is classed as a hearing loss, and a greater decibel value indicates a greater level of severity. For example, mild hearing loss is present in the 20 - 40 dB range and severe loss is shown at 71-90 dB. WebDisabling hearing loss affects aging adults more as people get older.
