- - - - Normal ABR
    - - Normal OAE
  - - - Duration Pattern (DPT)
        
        Difficulty with both humming and labeling
      - Frequency Pattern Test (FPT)
        
        Poor pattern recognition, verbal/humming gap (less than 70% score)
    - - Random gap detection test
        
        Higher gap detection threshold (more than 10ms to detect a gap, normal should be ~2-5 ms)
      - Competing Sentences Test (CTS)
        
        Individuals may repeat both sentences, confuse content, or miss the target ear's sentence
    - - Filtered speech
        
        Lower than normal word recognition scores
