AC to BC ratios that differ markedly in each ear - UNILATERAL HEARING DEFICIT

SENSORINEURAL HEARING LOSS: finding will also be AC > BC, damage to inner ear (cochlea) or damage to the nerve pathways between the inner ear and brain, decreases a client's ability to hear faint sounds or even loud may be muffles
