Hearing tests Flashcards
What are the two main hearing tests?
Rinne’s
Weber’s
What does Rinne’s test involve?
Tuning fork is placed over the mastoid process until the sound is no longer heard, followed by repositioning just over external acoustic meatus
What is positivie Rinne’s test?
Air conduction (AC) is normally better than bone conduction (BC)
What is a negative Rinne’s test?
Bone conduction (BC) being better than Air conduction (AC)
What would a negative Rinne’s test suggest?
Conductive deafness
What does Weber’s test involve?
tuning fork is placed in the middle of the forehead equidistant from the patient’s ears
the patient is then asked which side is loudest
What result from Weber’s might suggest unilateral sensorineural hearing loss?
Sound is localised to the unaffected side
What result from Weber’s might suggest unilateral conductive hearing loss?
In unilateral conductive deafness, sound is localised to the affected side
What result from Weber’s might suggest unilateral conductive hearing loss?
In unilateral conductive deafness, sound is localised to the affected side
What results would suggest sensorineural hearing loss?
Rinne result: Air conduction > bone conduction bilaterally
Weber result: Lateralises to unaffected ear
What results would suggest left sided conductive hearing loss?
Negative Rinne test (BC>AC) to the left ear and the sound lateralizing to the left ear on the Weber test,
What results would suggest right sided conductive hearing loss?
Negative Rinne test (BC>AC) to the right ear
Sound lateralizing to the right ear on the Weber test
What results would indicate Right-sided sensorineural hearing loss?
Positive Rinne test (AC>BC) bilaterally
Sound lateralizing to the left ear on Weber test
