Hi, in physics class the teacher was using an oscillator to demonstrate how older people can't hear noises that are as high when compared to children. He started at 20Hz and moved it up gradually to 20KHz. I couldn't hear any sound past 7.5KHz, while most people could hear up to 19KHz! Should I get this checked because it's a huge difference in hearing range. I wouldn't think it's a problem, The only things I can't hear in everyday life are crickets and the sine wave noise from the TV if it's set to an AV channel with no picture output.
