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. WebThe most common PTA definition found in epidemiological, or population-based, studies is the four-frequency average of 500, 1000, 2000, and 4000 Hz. As the PTA increases, the hearing ability decreases. Normal hearing for speech is observed in adults with PTAs of 25 dB HL or less. At a PTA of around 40 dB HL in both ears, most people are ...
