Interpretation
| Weber's | Rinne's | |
|---|---|---|
| Normal | Midline | Air conduction > bone conduction bilaterally (normal) |
| Conductive HL | Localizes to side with HL | Bone conduction > air conduction (abnormal) |
| Sensorineural HL | Localizes to side w/o HL | Air conduction > bone conduction (normal) |
