I Have High-Frequency Tinnitus from Noise Trauma, But I Can Hear a Dog Whistle...

I have extremely high pitched tinnitus in both ears which I'm led to believe mean I lose hearing at high frequencies. However I can hear things like a dog whistle surely If I had damage at high frequencies you cannot get much higher than a dog whistle.

 

Also damage means that you still hear those frequencies but only at higher volume so you may hear a dog whistle but not if its too quiet or far away hence the tinnitus
In most cases each ear has damage at different frequencies so used together they can hear sort of okay but because of the imbalance of hearing signals coming into the brain you have a tinnitus recreating those left and right poor frequencies separately and mixing it back amplified into the brain
That's why the tinnitus seems louder than the actual hearing loss

 

Do you know what caused these issues @Digga ?

 

I was out with friends one day in the car and they put the radio on full blast and every beat felt like a pounding to my ears after 2 mins I told them to turn it down but it seems a little to late. At first the t was very quiet I could only hear it when lying down but then one time a fire alarm went off and from there it has got worse
