Tuning fork (512Hz): 

A tuning fork is a metal instrument with two prongs  and a handle. When struck, it vibrates at a specific frequency, producing a musical tone. The vibrations produced can be used to assess a person's ability to hear different sound frequencies. A vibrating tuning fork is placed next to the ear or against the skull to vibrate the inner ear, helping to determine if hearing loss is present.
