One man had 30 dB deafness in left ear with Weber test showing more sound in left ear and BC (Bone conduction] more on left side and normal hearing in right ear, his test can be summarized as:
ExplanationA. Weber’s test - left lateralized; Rinne’s right positive; BC > AC on left side
Let us analyze each information provided in the question.
● This man has deafness of 30 dB in left ear.
● Weber’s test is lateralized to left ear i.e. deaf ear which means deafness is conductive type. (As in conductive deafness - Weber’s
test is lateralized to poorer ear).
This means Rinne test should be negative on left side (as in conductive deafness - Rinne test is negative). Ruling out options “b”
and “d”.
In the question it is given hearing is normal on right side, so Rinne test will be positive on right side (because in case of normal
hearing - Rinne test is positive).
In the question itself it is given, bone conduction is more on left side. So option “a” is correct i.e.:
Weber’s test - left lateralized, Rinne test - right positive and BC>AC on left side.
