Air-Bone Gap

Category:

Question:

How many decibels constitute an air‑bone gap? 

Answer:

When a 10–15 dB or more difference is measured between the air conduction and bone-conduction thresholds in the same ear, you have an appreciable air-bone gap. This means there likely is a conductive or mixed hearing loss present.
