Possible diagnosis is40 db SNHL in left ear, right ear normal40 db CHL right ear, left ear normal40 db CHL both earProfound hearing loss right ear, left ear normal  <response>: There is a conductive hearing loss in the right ear.Left ear normal. A prediction of an air-bone gap can be made if tuning forks of 256, 512 and 1024 Hz are used.A Rinne test equal or negative for 256 Hz but positive for 512 Hz indicates an air-bone gap of 2030 dB.A Rinne test negative for 256 and 512 Hz but positive for 1024 Hz indicates an air-bone gap of 3045 dB.A Rinne negative for all the three tuning forks of 256, 512 and 1024 Hz indicates an air-bone gap of 4560 dB.
