Bekesy audiometry in diagnosis of sensori-neural deafness

From the present study it was concluded that Bekesy audiometry test is the most useful battery of test in diagnosis of sensori-neural deafness. The reasons are:— (a) The results are reliable and it is consistent with the results of other batteries of test. (b) Patients who are cooperative in doing other special audiological tests, can follow this simple test. (c) It shows type I and II patterns in cochlear and combined lesions and type III and IV in retrocochler lesions. (d) Single test will give an idea about hearing threshold, pattern, difference limen for the intensity and tone decay. So when a classical pattern is obtained, there is no need to go for other battery of tests, which is more time consuming.
