  1. Noise damage is not invisible. You can easily notice it with just your phone and any app or online service that can produce a sound of certain frequency and loudness. Your phone speaker is most probably able to emit sounds up to 20kHz and beyond, so the only thing that can prevent you from hearing the high pitch sounds is your own hearing loss. btw the C9 note is 8372Hz and C10 is 16744Hz respectively your limit is probably somewhere in between p.s. there are also numerous diseases that may lead to hearing issues, so noise may be not the main problem in your case
