The following data table below lists the driving frequencies (fD) along with the respective measured values of the amplitude (A) at that frequency. The amplitude was obtained by placing a Microphone inside the Tuning Fork Box and measuring the voltage output on an Oscilloscope.  This can be done with any Tuning Fork Box. Old Data
