I am in the process of replacing the tube on my BTE.
I read online that if you have severe to profound hearing loss, you should use a thicker tube as it helps with the sound and sometimes with feedback on powerful hearing aids.
I know right now I just have the standard tube thickness, .076 X .122.
I am thinking of trying a thicker tube, .076 x .130
Has anyone here heard of this, and does anyone know if it does help with sound.
