I am a 23 year old boy, and I had some difficulties in hearing, I did Tuning Fork Tests/(PTA) Audiometry three months ago which indicates that my Hearing threshold level in dB increases from 10 to 70 as frequency increases from 250 Hz to 8000 Hz for both right and Left ear, Also I did that test when i was 10 but both test result are Identical. I am wondering if there is any way to improve my hearing without hearign aids, and which type of hearing aid do suggest me?
