Frequency of tuning fork used to test vibration sense is

(C) 512 hZ # TUNING FORK TESTS: These tests are performed with tuning forks of different frequencies such as 128, 256, 512,1024, 2048 and 4096 Hz, but for routine clinical practice, tuning fork of 512 Hz is ideal.> Forks of lower frequencies produce sense of bone vibration while those of higher frequency have a shorter decay time and are thus not routinely preferred.> Tuning Fork Tests: Rinne test Weber Test Absolute bone conduction test Schwabach's test, Benign test, Gelle's test
