This aluminum tuning fork is precision-tooled to produce a frequency of 512Hz, the standard frequency used in various hearing tests. The fork features plain shanks with a round stem that allows a secure finger grip while minimizing physical contact for optimal sound wave transmission. The fork measures 6.25 inches long, 1 inch wide, and 0.4 inches in height. Its aluminum construction resists rust and tarnish. It is suitable for physics sound wave demonstrations, musical instrument tuning, and acoustic resonance experiments.
