survey conducted in theUnited Statesclassified 25.9 per 1,000 persons aged 65–74 as blind, in contrast to 1.3 per 1,000 aged 20–44 years. In the age group 65–74, 54.7 per 1,000 persons were classified as functionally deaf, compared with 5.0 per 1,000 in the age range 25–34 ...
hearing range can vary between individuals based on genetics, age, and exposure to loud noises. For example, as we age, our hearing range tends to decrease, particularly in the higher frequencies. Exposure to loud noises - such as attending concerts or using headphones at high volumes - can ...

The hearing range of humans gets worse with age. People lose the ability to hear sounds of high frequency as they get older. The highest frequency that a normal middle-aged adult can hear is only 12-14 kilohertz. Also, the hearing range for men worsens more quickly than the hearing range...
We further calculated the DV slope by using a linear fitting of DV within the range of 200 ms after stimulus onset to the time of choice. Data preprocessing Prior to performing analyses, we visually inspected the signals recorded from all electrodes and excluded those that exhibited epileptic ...

As in results from previous cross-sectional studies, hearing loss in the males 70 years and older is greatest at the highest frequencies. The rate of change for these older males is faster in the speech-range frequencies 0.5-2 kHz than in the higher frequencies, since their hearing has ...
