Tinnitus hearing issue. Regular tv.

Hello I am very concerned for my sister. She has issue since many years. Lot of sounds can be heard..and this is amplified when in stress and can be heard clearly when there is pindrop silence. She suffered from typhoid when 15yrs old..later in middle age she went to some clinic and a hearing aid of worth 20000 Siemens brand was provided by Rajan hearing centre in Bangalore. But this aid used to amplify the sound not only what needs to be heard but what was existing noise in head, was also amplified. Pls some one genuinely suggest away to treat tinnitus...as we are middle class people and cannot experiment with casual opinions.(not pointing at anyone but just frankly infoirming) I feel heartbroken seeing the situation that she can't listen to people unless they speak loudly..cant watch regular tv... Eagerly waiting for valuable response.
