<prompt> Tuning fork of 512 FPS is used to test the hearing because it is -Better heardBetter feltProduces over tonesNot heard  <response>: Tuning fork tests can be done with tuning forks of different frequencies like 128, 256, 512, 1024, 2018 and 4096 Hz but most commonly used is 512 Hz becauseTests are done with various tuning forks, but 512 Hz is the most commonly used as it has longer tone decay and sound is quite distinct from ambient noise.Forks of lower frequencies produce a sense of bone vibration while those of higher frequency have a shorter decay time and therefore not commonly usedRef.
