WebTuning forks, typically aluminum, consist of a stem (handle) and two prongs that form a U -shaped fork ( Figure 4-13 ). The tuning fork vibrates at a set frequency after being struck on the heel of the hand and is used to assess vibratory sensation and hearing (air conduction and bone conduction). Hold the tuning fork by the stem, not the prongs. Web29 de jul. de 2024 · High-frequency hearing loss isn’t reversible, but in some cases, it is preventable.
