At what frequency are tuning forks typically set for testing?

Tuning forks used for testing in audiology are often set to specific frequencies that can effectively assess hearing loss and other auditory functions. The choice of 256 Hz is significant as it falls within the range that is commonly used for tuning various musical instruments and also provides a good balance for conducting auditory tests, particularly in assessing hearing sensitivity and the ability to perceive low-frequency sounds.

When using a tuning fork at 256 Hz, this frequency enables clinicians to perform various tests such as the Rinne and Weber tests, which help in differentiating between conductive and sensorineural hearing loss. The 256 Hz frequency is low enough to be useful for evaluating lower frequencies where many hearing losses first manifest.

Other frequencies listed may have their own applications, but 256 Hz is particularly standardized in clinical practice for these specific audiometric tests, making it the most relevant choice in this context.
