Values are pure tone bone conduction thresholds for the given frequency (in Hertz). WR= word recognition using a 50 item assay. CNT= could not test due to limits of the equipment
*
interpret with caution because patient Arabic speaking
"-" not available
*
excluded because WR testing limited by equipment
