Should I seek a second opinion from a different doctor?

So over the past year i've been noticing a difference in hearing; i can hear noise, but often it sounds garbled in one ear and i cannot understand exactly what is being said to me. I went to an audiologist and she did a full testing, but told me my hearing was fine, no loss. I took my audiogram but my friend who is a speech pathologist, upon looking, told me that it seemed as though one of my ears had hearing loss of up to 15 decibels in certain frequencies. Which, doesn't technically count as hearing loss yet, but considering I'm 21 and this happened randomly I dont know if I should seek a second opinion?
