9.9  The audiogram tab 

The following section describes the elements of the 

Audiogram Tab

. 

The 

Audiogram Tab

 is where the resulting estimated audiogram is displayed and correction factors can be 

modified.  

 

 

9.9.1  Estimated audiogram 

 

The estimated audiogram is generated during recording based on the ASSRs detected.
