You can go through articles online which says damage happens in microstructures of inner ear
when we are getting exposed to noise from day one. But these are at the level of micro structures so wr think we do not have loss.
Usually we get to know we are having loss when its get worse.
Apart from these medical facts, you jus get one things without delay you have to go for audiometry test
(Pta, speech audiometry
. That will give you the exact amount of loss you are having now. Better to avoid listening through earphones and use in loudspeaker mode with moderate sound level.
Do not go beyond the pemitted sound level while using ear
phones. You can see the alert pop up message whenever you go beyond the permitted level. If not install Volume limiter app from google
Give feedback if it helps. Thanks.
