The theoretical background is given in the set of papers Rossing’s Acoustics of Bells. A vibrating bell produces many frequencies of sound, each produced by a different vibrational mode […]

Frequency calibration for tonal analysis

The basic principle of frequency calibration is simple. If a reference tone of known frequency is available, it can be recorded along with the bell sound. When the bell sound is later analysed, the frequency of the reference tone is checked at the same time. If there is a discrepancy, work out the ratio of […]
