What Is TFI or Tinnitus Functional Index?

The Tinnitus Functional Index (TFI) is an internationally recognized tool that is highly regarded among tinnitus treatment experts. Offering initial insight into tinnitus severity and how a patient has been negatively impacted by the condition.

When used pre and post therapy, the TFI can determine how a patient’s quality of life has been changed through use of the Levo System. The TFI is also the only tinnitus assessment tool that evaluates sleep – a key interest to most tinnitus patients.


The Tinnitus Functional Index (TFI) was developed by Oregon Health & Science University (OHSU) Scientists.
