Air threshold differences of at least 40dB between ears.
A shadow curve on the audiogram is a false audiogram curve that is obtained when sound presented to one ear is heard on the opposite ear. This audiogram is recorded in instances of monaural deafness.

Air conducted stimulus may be head by the contralateral normal ear in unilateral deafness. It is represented as two thresholds connected on a graph with a line. The air threshold difference between the two ears ranges from 40dB to 80db in a shadow curve.
Hope this helps.

Air threshold differences of at least 40 db between the left and right ear is refered to as a shadow curve. Air conduction masking needs to be used at any frequencies in which a 40 dB gap is present between the left and right thresholds.
