Weber and Rinne Test – Clinical Examination
The clinical examination of hearing loss should include differentiating between conductive and sensorineural hearing loss. There are different causes of sensorineural hearing loss, such as inner ear disease or damage to the cochlear nerve. In all cases, the perception of sound waves via both air and bone conduction is impaired. Sounds reaching the affected ear will therefore be perceived to be quieter than on the unaffected side.
Conductive hearing loss on the other hand is caused by diseases of the middle ear, such as otosclerosis or otitis media. Obstruction of the outer auditory canal, as seen in cerumen impaction, for example, can also lead to conductive hearing loss. In this case, air conduction of sound waves from middle to inner ear is impaired. Bone conduction, however, is unaffected and causes sounds on the affected side to appear louder.
There are two hypotheses that attempt to explain this phenomenon. First, it is assumed that impaired sound conduction causes upregulation of the inner ear, which makes it more sensitive towards stimuli received via bone conduction. It also causes these sounds to be perceived as louder. Second, if sound waves cannot easily reach the inner ear, they probably cannot exit it easily either. These trapped sound waves could therefore make patients perceive sounds as louder.
The Rinne and Weber tests are easy and quick methods for differentiating simple forms of conductive and sensorineural hearing loss. More complex illnesses, such as combined conductive and sensorineural hearing loss, often result in test results that are difficult to interpret.

We used your vides today in Neurophysiology Lab at NUHS Pinellas Park, FL. THANK YOU!
To clear up a point of possible confusion it's Important to note that a normal result for Rinne's test is paradoxically called a positive Rinne test.
Brilliant breakdown.. I'm so thankful for this video
Excellent explaination….and also the problems at the end were great …..greatly appreciate🤗
Best explanation I have had . I am no longer confused
Thank you very much 💞
Keep coming back to this!
Excellent video!
Very well explained…this shit…godsend viedo to all med students …😅
Lets just acknowledge that Amboss is the best thing that has ever happened to clinical medical education.
If you want to study thoroughly you should read the health Assessment of Weber and janet
this is the best explanation ever
seriously, med school professors never took the time to explain this fully
Excellent video! Thank you!
After watching this video 4times… I finally understood the concept well.. Thanks for uploading
Well explained!
Fantastic explanation
I've spent so much time browsing through videos and failing to understand until this particular tutorial,,,,, thank you sooooo much this makes me feel better since i had missed the prac class initially.
this was so clear 🙂 thank you !!
Wow! I finally understood this! Thank u 🙂
Thank You So Much. Knowledge is Power
Sounds normal why do most people go to clinic
Brilliant explanation…. Would definitely help lot many students such as myself … Thankyou ❤️
i also like the sample case, makes me understand more
tysm 🥺🥺 im so grateful for this
Really helpful
Thank you so much
Beautifully explained 😊😊 finally im able to get this concept
Thank you so much. Very helpful
Finally😃😃😃
Made this hard topic a piece of cake! Thanks!
Only time this has ever begun to make sense for me thank you
thank you
Great 👍
Amazing
At last i understand what in d hell is rennie + – and weber + -..also what in d world is wrong with air and bone conductions🤗🤗🤗🤗🤗🤗
A grace sent from haven … thank u 💜
hands down. best video ever!
amazing video. Thanks a lot
Thank youuuu! I FINALLY understand this.
Very well explained
Nice teaching
Good stuff, I've spent the first 3 years of med skl not understanding this concept at all!!! I think I finally get it.
In 1st year of PT school, one of our lab practicals was to demonstrate and explain both of these tests in 1 minute.
Easy but confusing
The best discussion about weber and rinne..even better than my professors😂
Especially when they gave examples..it made it even more clear.thank you so so much!
Best combo video on Weber and Rinne tests.
cant explain how easily that was illustrated, loved it
Most comprehensive.. Thanks
Best video ever seen about the subjects. The idea of analyzing some questions about the tests was also great. Thanks a lot.
Thank you Sooo much❤️
Why bone conduction is increased in CHL? (BC>AC)because of AC decrease only or because of AC decrease and BC increase .which one???
