Schwabach test

The Schwabach test compares the duration of bone conduction hearing of the test ear with the normal ear. The Schwabach test compares the duration of bone conduction hearing of the test ear with the normal ear. Abnormal results: (1) If the bone conduction time of the affected ear is longer than that of the normal ear, and it is recorded as ST "+" for the bone conduction comparison test, then the affected ear is conductive deafness; Short, short for the bone conduction contrast test, marked as ST "-", the affected ear is sensorineural hearing loss.
