Frequency of the hum tone generally changes linearly with the diameter (at the strike point). The volume of bronze, and hence its weight will increase by a factor of the cube of the diameter. However, foundries use a thicker profile on smaller bells so that they will ring loud enough to compete with the larger bells. The diameter to weight rule of thumb does not generally work for bells smaller 15 inches in diameter because of the additional bronze. | Frequency of the hum tone generally changes linearly with the diameter (at the strike point).
