Of all the different types, this is the most common form. It is generally a consequence of loud noise exposure. If you have subjective tinnitus, you are the only person who can hear the sounds.
In mild cases, subjective
tinnitus disappears quickly. For some, it comes and goes with varying lengths and intensities. Severe cases can last from three months to twelve months, sometimes even longer. When the internal noises overpower external sounds, your ability to concentrate can suffer.
Audiologists often recommend hearing aids as a means to play calming noise. Doing this can help distract from the hissing, buzzing, and ringing sounds.
